And now, a word from our sponsors.

March 17th, 2010

Happy crack o’ dawn to you.  I’m Joey Fishlips, and this is OMG’s Not Really News: dredged up from the seabed in massive trawls that cause nigh-irreparable damage to precious corals, then sent right to your table in little bitty cans. 

Today’s headliner is sports-related and political, the killer combination.  An African dictator who shall remain anonymous challenged a sack of potatoes to a boxing match, which he then lost.  Eyewitness reports from the several thousand forced onlookers, many of whom were being menaced by big shiny guns at the time, claim that the tyrant’s downfall was his inability to compensate for his dangerous habit of punching himself in the face when he wasn’t looking properly.  “I sure am glad that we toil fruitlessly and die futilely without an ounce of joy under our Glorious Leader, Sir ******,” said our interviewee.  “He’s so charmingly klutzy and clueless that you can’t help but chuckle whenever he orders another ethnic purge, the lovable little scamp.”  Upon being informed of his loss, the despot attempted to have the government-appointed referee executed, but found to his dismay that it is extremely difficult to hang a bull elephant.  We’ll follow up on his whacky, dictatorial attempts to make the official standardized rope of his country four-inch-thick titanium chain tomorrow. 

The Vancouver Winter Olympics have ended, but they aren’t the last word in this year’s sports.  The perennial Angriest Man in the Whole Wide World competition (located at its traditional site: Disneyworld) took place last week.  The event consists of airdropping the contestants over the Epcot centre, equipped with parachutes and megaphones, which they are encouraged to use to engage each other in casual, harmless conversation.  Up to 20% of the competitors are eliminated in the five minutes before reaching the ground, and the remainder of the event typically lasts about half an hour, give or take ten minutes depending on whether or not someone landed near a toolshed and was able to quickly acquire some sort of crowbar, sledgehammer, or otherwise blunt instrument.  The winner this year was Franklin N. Trepan, who incapacitated his final opponent by squirting high-pressure blood from his eyes in a manner not unlike that of the horned toad, if it were fuelled by single-minded rage and hatred towards all that lives.  Mr. Trepan was unavailable for comment, as we believe he may have eaten our camera or cameraman. 

A heartwarming story of success: bit actor Harlan Spinner has, as of the completion of his last acting role, officially played over forty separate gratuitously offensive stereotypes.  “Muchos gracias senor!” said Spinner, eyes comically rolling around like crazy on being presented with his large, ugly trophy.  “Mamma mia, this shit’s a-heavy!  Real gold-painted lead?  For moi?  C’est impossible, zut alors!”  His acceptance speech, though dramatic and visually compelling, was somewhat indistinct, marred as it was by half of it being delivered in an ultra-thick gangsta rap, the other half in guttural vaguely Nordic screaming, and a small case of stuffiness due to his cold.  All was set well again by the post-awards ceremonial lynching of Harlan; committed by nineteen different ethnic groups, the angry mob was a moving and uplifting gesture of joint effort and community. 

Anger is not the only emotion of the day of course – its polar opposite is love.  Which we’re very short on, so here’s a story about something else.  An anonymous North American man realized last week over his morning Cheerios, with dawning comprehension accompanying each laborious spoonful, that he was in fact the most boring person he’d ever known.  Confused, he sought verification, phoning up each and every one of his sluggardly slaggard friends, all of whom confirmed that he was the most boring person they’d ever known.  They asked their friends, who agreed, and they asked their friends, and so on.  This chain of events slowly wrapped itself about the globe over the past week, and apart from a four-hour period when there was thought to be a man in Chad that was substantially duller (disqualified when it was revealed he was a malnourished and taller-than-average chicken), no challengers emerged.  The misfortunate champion of the apathetic and unrelatable was crowned “king of the dullards” yesterday at an Iowa yard sale, in a ceremony attended by half a flock of pigeons and one old man who wished to complain to someone.  His first edict was to go home and nap. 

An elderly woman and grandmother of eleven finally revealed her true, sinister colours in Chicago today, when she successfully tricked her entire family into forfeiting their souls to her during a Monopoly game in a crafty and complex gambit involving dark magic, several contradictory and fiendishly-worded agreements and pacts with horrifying nether-powers, and a palmed “Chance” card.  Doreen McIntyre, 94, says that she just needed the souls as a starting point.  “I’ll wager I can parlay a few of them into eternal youth, maybe some blasphemous sorcerous powers, and then just buy-and-sell my way up,” the thrifty diabolist said as she carefully stitched the wailing spirits of her kin into a sampler displaying some kitties.  “The way I see it,” she continued, hexing charms of death and destruction to humankind into the edges, “if I take it slow and steady, I should be in the clear to be an archfiend by the next centennial sabbat.  A soul saved is a soul earned.” 

As we wrap up our news segment, we’d like to issue a correctional statement: one of our movie reviewers described an action film as “a rip-snorting” adventure.  Clearly, as was pointed out in over eighty pounds of angry spam, he meant “rip-roaring.”  Reviewer Eddie Jubbles has been suspended from service for eighty hours and had his larynx pawned.  I believe I speak for all of us when I say this is great, except for maybe Eddie.  But we’re not sure, since none of us here at OMG speak sign language except for the gorilla, and she’s on vacation. 

Finally, a word of encouragement: the northern coast of the nation of France has finally returned from its duel with Pluto, eyes bloodshot, splendid quantum-singularity armour in tatters, and with a pronouncedly funny walk.  When asked what had occurred between it and the renegade not-a-planet, France said “Oh fuck, I don’t want to talk about it.  It’s just, just too much of a deal to go over right now, okay?  Ask me later.”  An anxious request to know if France had triumphed in its goal, the country paused in its exit long enough to shrug its shoulders and say “Yeah?  Yeah, I guess so.  It’s pretty good, sure.”  France then departed for San Francisco, stating its intent to “get drunk and hook up with something.”  This may be connected with the overnight absence of the Golden Gate Bridge, and its apparent hangover this morning. 

 

None of this happened, but it’s very possible that, if you wished upon a star at the right time in the right place with the right person, it still never would’ve, ever.  I’m Joey Fishlips, and if you’ll excuse me, I have to see a man about a carp right now.

On Snakes: Strident Sibilants Spoil the Serpent’s Spoken Statements.

March 10th, 2010

In our ongoing efforts to plunder, loot, and pillage the class Reptilia for everything it’s worth, this week we’ll be look at the svelter, slighter, and somewhat more-demonized snakes.  Yes, I know modern media hasn’t been the kindest to crocodiles either, but it’s harder to beat them up. 

If you can wish harm upon this face, you legally have no soul.

If you can wish harm upon this face, you legally have no soul.

As always, we’ll open the playing field with some useless information upon the denizens of the suborder Serpentes.  They don’t have any front legs (some of the more primeval species, like the boas and pythons, have fun little doohickeys called “anal spurs” that are the vestigal remnants of the hind legs and located exactly where you’d expect).  The exact moment that a bunch of lizards decided that having limbs was a mug’s game and went off the rails and into the flat, squirmy yonder is unknown (delicate skeletons make the fossilization process cry inside), but our earlier snake fossils pop up around 150 million years ago in South America and Africa.  Also, in an unrelated but highly excellent fact, the mosasaurs (which arose in the Early Cretaceous and pretty much took over as the dominant marine reptile from then on to the K-T extinction) are extraordinarily close relatives of theirs. 

Seventeen metres of snakoid goodness.

Seventeen metres of snakoid goodness.

This isn’t to say that the snakes themselves weren’t up to any great shenanigans.  They trotted along (figuratively speaking), persisted quietly through the Mesozoic and so on and so forth, but their real glory was kicked up a notch in the Paleocene, lasting just after the Cretaceous extinction to about 56 mya, where they discovered that (A) most of the big things that competed with them for food were gone and (B) hey there’s an awful lot of those little furry tasty buggers running around.  It was a sumptuous time. 

Modern-day snakes mostly fall into three broad groupings, two families and a superfamily, to be precise.  There are outliers, many of which are blind or burrowing snakes and eat earthworms, so we’ll be looking at some of the more “classic” examples.   As a final note before we embark, there will not be a single case of elongated “s’s” in this entire demi-article.  They are silly and stereotypical and you should be ashamed of yourself for ever associating them with anything as slithery and noble as the snake. 

Despite the anaconda having no proven human kills, it CAN eat crocodiles, caimans, and tapirs.  So hands off.

Despite the anaconda having no proven human kills, it CAN eat crocodiles, caimans, and tapirs. So hands off.

Boidae
The Boidae family has, well, boas and their relatives.  None are venomous, and the family itself has a decent backlog of primitive features (that is, older ones – not outmoded).  The anacondas, including the friendly and ginormous (weightiest of all snakes, with a current record of 214 sinuous pounds), are boas, and the most charmingly aquatic of the lot, spending much of their time doing the reptillian version of snorkling.  Rule of thumb has boas in the New World and pythons in the Old, but that isn’t as accurate as it could be (boas in Madagascar and Fiji, among others), so just stick with “isolated areas.”  Elsewhere it’s pretty much all…

How can you resist that expression?  If you'll fall for those evil little grins dolphins wear even as they kill younger dolphins, this should be easy.

How can you resist that expression? If you'll fall for those evil little grins dolphins wear even as they kill younger dolphins, this should be easy.

…the Pythonidae family, which lazily suns itself from Africa to across Asia and all the way to Australia.  Again, non-venomous, and has the same basic feeding strategy as the boas: constriction.  You wrap yourself real fast around your unfortunate meal item, then hold tight – but you don’t really squeeze.  No, you just tighten yourself to the same degree of firm-but-as-unyielding-as-steel-wire every time it exhales, resulting in inability to struggle, move, breathe, or stay alive.  Then you eat it.  The reticulated (or “regal”) python is the longest of any snake, capable of wandering north of 28 ft.  It also, as I have said before, is surprisingly unlikely to kill you.  Many things are.  In fact, on this planet, the only thing that’s more likely than something not killing you is something killing you. 
Wait, what?

Xenophidia
The third grouping breaks the mould and the entire point of my attempt at pretending we have three equalish groups here by being a superfamily, a name well-earned because it has over 3,000 species in it (combined, the boas and pythons have well under a hundred).  Xenophidia has almost every poisonous snake, from the rear-fanged Colubridae family (home of two-thirds of all living snakes), the hinged-fanged Viperidae (including “pit vipers”), the sea-going Hydrophidae (that’s “sea snakes” to you and me and the man standing behind you very quietly right now), and the Elapidae, which boast the cobras.  We’ll be giving the lot of them quick comb-overs, which are exactly as useful as the other sort. 

A boomslang should seldom be confused for a boomerang, and never more than once.

A boomslang should seldom be confused for a boomerang, and never more than once.

Colubridae
The Colubridae is what you might call a mixed bag, or less charitably, the snake equivilant of the mixed-parts bin, or possibly an oversized rummage sale.  It isn’t even a proper natural/monophylatic grouping – many of its contents aren’t common descendants of an ancestor (which is sort of the situation for the popular terminology of “reptile” – if we wanted to be accurate, we’d have to put every bird in that category).  This disunity has resulted in an enormous hodge-podge that has no unifying or notable characteristics – they aren’t even spectacularly poisonous, barring odd exceptions like the entertainingly dubbed boomslang (afrikaans, “tree-snake”) which has very large pointy teeth at the back of its mouth with which it can murderate you most thoroughly. 
Sluggish, grumpy, and prone to biting.  Just like many of our relatives, I'm sure.

Sluggish, grumpy, and prone to biting. Just like many of our relatives, I'm sure.

Viperidae
The vipers have minced over much of the planet, sparing only Antarctica (traditionally snakeless for obvious reasons), Australia, and a clutch and a passle of islands like Madagascar, New Zealand, and Ireland.  All vipers have a pair of long fangs at the front of their mouths that can swing back nicely on little hinges, thus giving them optimum penetration power without the inconvenience of big teeth getting in the way of swallowing food or snapping off.  Also, all their scales are keeled – they have a slight ridge running down the center, making them a little rough rather than smooth.  The venom of choice, as a rule, is based around proteases – enzymes that digest proteins, leading to owies, soreness, boo-boos, dying flesh and cells, and blood pressure going for a trip on a trapeze while clotting takes a lunch break and lets his mentally handicapped brother Clyde take over.  Some of the enzymes help break down and pre-digest food, which is great because viper digestive systems are somewhat limited. 
Vipers contain the notable subfamily Crotalinae, the pit vipers, termed by their heat-sensing organs located one on each side of the head, ‘twixt eye and nostril.  The pit organ is highly sensitive, and an invaluable aid for any night-hunting predator – especially one hunting after succulent, warm-blooded rodent flesh.  The group contains the large bushmaster (12 foot!), the rattlesnakes, and other family favorites such as the fer-de-lance, sidewinder, and the moccasins/copperheads. 
One of the world's most affectionate and venomous creatures.  Can't you see all it needs is love?

Hydrophidae
The sea snakes are closely related to the elapids, sharing with them a predilection for delightfully deadly neurotoxins and many physical traits (those that haven’t been adapted for sea travel.  In fact, they’re so taxonomically similar that there’s talk of just giving up on the whole family and relegating its inhabitants to various locations in elapid subfamilies, and this may in fact be the current state of affairs.  Look, if you want more information, read a book or something by someone who knows what they’re talking about.  At any rate, they’ve taken to the life aquatic like a duck to water – their lung runs almost the entire length of their body to aid buoyancy and manage air, their ventral scales (the ones on their undersides) have become reduced to the point where land travel would be downright impossible in many cases, and their tails are veritable paddles.  Some of them are reported to be extremely docile when it comes to biting, but others have less qualms.  They live out their entire life cycles at sea, and when brought out of the water are unable to even coil up or strike properly (although they do apparently get quite distressed and aggressive during this, so try not to get too grabby). 
Do not attempt to wrassle.  It would only irk him.
Do not attempt to wrassle. It would only irk him.

Elapidae
Elapids include some of the most venomous snakes in the world (just like sea snakes, which they also may contain, as said above), coupling incredibly potent venomwith somewhat less sophisticated delivery mechanisms.  Their fangs point backwards slightly and tend to be a bit stubby, requiring them to actually bite something full-out as opposed to simply stabbing and juicing.  A couple elapids (like the spitting cobras) have mastered the fun trick of spewing venom out of the tips of their fangs thanks to forward-facing holes at their tips, reaching up to around six-and-a-half feetish at maximum.  The venom itself is nasty, and is most often neurotoxic, causing muscle paralysis and eventual inability to breath, which is usually the killing factor.  Elapids themselves aren’t as widespread as vipers, mostly in the tropics to subtropics of the world.  Beyond the cobras (including the King Cobra, an 18-foot powerhouse and the world’s largest venomous snake), famous elapids also include the mambas (including the Black Mamba, both the largest venomous snake in Africa at 14 ft maximum and one of the fastest worldwide, capable of hitting 10-12 mph), and the entire genus of the Taipan of Australia, the species of which seem mostly to be rivalled in overall venomousness by each other

 

To end this useless monologue on a helpful note, here’s some advice: don’t screw around with snakes.  It’s better for all involved, especially the snake.  And barring the odd asshole species like the puff adder (which likes to sit in the middle of trails being camouflaged, is too lazy to move when something comes near, and announces its presence by biting whatever annoys it), for the most part they’ll leave you alone if you leave them alone.

On Alligacrocaimanadillos.

February 17th, 2010
Today’s topic is going to be one of the few orders of creatures on the planet that you could totally imagine wandering around dinosaurs, giving them ‘sups.  Or eating them.  Whatever.  Ladies and gentlemen, the order Crocodillia
This is not an alligator.

This is not an alligator.

There are several important basic facts about the crocodillians in general that we should brush over.  First, they have easily the most powerful bites of any living animals – 5,000+ pounds per square inch, five times that of the hyena, whose hobbies include crushing bones in its mouth for marrowy goodness.  Second, they (and birds) are the only remaining Archosaurs (infraorder Archosauromorpha), the “ruling reptiles,” whose name is rather hard to argue with when you consider that it also included dinosaurs and pterosaurs.  Producing the largest land animals and flying creatures of all time along with some pretty damned impressive watergoers is no small thing to sneeze at.  Third, they are not armadillos. 

This is not a crocodillian.  Remember that.

This is not a crocodillian. Remember that.

Beyond this, the order itself can be shoved into two major families: Alligatoridae (Alligators and Caimans) and Crocodylidae (Crocodiles and Croquet mallets).  Neither contains armadillos,  who are members of the mammallian superorder Xenartha, which also contains sloths and anteaters, giving its members a notable tendency towards being dumber than a brick sandwich and twice as ugly, yet strangely adorable in an utterly grotesque and dopey fashion.  They also all have prominent claws, whether for burrowing and grubbing (armadillos), tearing apart gigantic termite mounds (anteaters), or dangling upside down from branches while expending no effort or brain cells. 

Now that that’s over with, let’s get down to nitty gritty details.  Specifically, we’ll be specifying the specific differences between alligators and crocodiles.  They’re well-known by everone under the age of fifteen or so, but I’ll restate them for you.
ALLIGATORS:
-Have wide, blunt, broad snouts with an almost U-shaped tip. 
-Have wider upper jaws than lower ones, so their lower teeth are almost never exposed when their mouths are shut.
-Tend to be darker coloured.
-Prefer freshwater slightly more, though they can live in seawater.
-Are less bitchy, cranky, and testy.

CAIMANS:
-Are slightly more agile and crocodile-oid than alligators.
-Live in Central and South America.
-Have longer and sharper teeth than alligators.
-Have bony back scutes as armour.
-Have a bone septum betwixt the nostrils

CROCODILES:
-Have longer, narrower jaws with V-shaped snouts. 
-Lower teeth often exposed when mouth is shut, due to equal-jaw-width.
-Are less concerned about salty water than alligators, due to specialized glands. 
-Are tetchy bastards.
ARMADILLOS:
-Are not crocodillians.
-Eat just about anything, although some prefer to eat almost solely ants.
-Are named from Spanish: “little armoured one.”
-Range in size from the pink fairy armadillo (4-5 inches) to the giant armadillo (5 ft.). 
-Are not crocodillians in any way, shape, or form.  Get this straight.

Now, on to the species!

 The Alligator (Alligator mississippiensis and Alligator sinensis)

This IS an alligator.  Write it down.

This IS an alligator. Write it down.

 The alligators are a less common lot than the crocodiles – there’re only two species around at the moment; the American (A. Mississippiensis) and the Chinese (A. sinensis), both of which are found pretty much where you’d expect.  Average size for the slightly bigger American is 13-14.5 ft. and 800-1,00 lbs, while the Chinese is hard put to broach 7 ft (especially in the wild, where they’re fairly fucked at the moment.  Prolific breeders in captivity, though).  Both species change diets as they grow (somewhat necessarily – although it’d be interesting to see a six-inch hatchling try to bring down a deer), but eat approximately similar things: starting out small with fish and invertebrates of all sorts, then working their way up to bigger fish and practically anything else that’s large enough to interest them.  Big Everglades alligators (that place sounds like a location in one of Tolkien’s notebooks) bring down black bears and cougars from time to time when they’re bored or peckish, so they’re pretty much at the peak of their game wherever they live.  Interestingly, they don’t automatically regard humans as food, although habituation, that feckless and careless whore, once again makes life difficult for everyone – an alligator used to people is no longer shy and that much likelier to try out your munchiness.  The other factor is carelessness: harass an alligator or go anywhere near its nest and you might as well write your will before you go, just to make things easier for everyone involved. 
The American alligator, as an aside, can handle cold the best of any crocodillian – weathering out winters underneath the surfaces of frozen ponds if needs must. 

 

American Crocodile (Crocodylus acutus).

This is not an alligator, and neither is the thing in its mouth.

This is not an alligator, and neither is the thing in its mouth.

One of the most prominent of the American crocodiles – of which there are quite a few, surprisingly.  There’s the Orinoco, Cuban, and Morelet’s crocodiles, plus this – although to be fair, none of them are in that great condition, population-wise.  All of their habitats lie within an area covering Central and South American to the Caribbean. 
The American crocodile itself can get larger than its alligatorish relatives – vile hearsay insists on up to 20 ft., although these individuals recieve food at bridge crossings regularly and thus can be considered to be on the crocodillian version of ‘roids – and is much more tolerant of salty water, although they suffer greatly from cold and are incredibly reluctant to head north of Florida.  No matter what size or age, fish is most of their diet – although they can eat pretty much whatever they damned well please. 

 

Nine-Banded Armadillo (Dasypus novemcinctus).

This is not an alligator and whoever told you so was a damned liar with a forked tongue.

This is not an alligator and whoever told you so was a damned liar with a forked tongue.

The nine-banded armadillo is absolutely not related to the crocodillians and is the most common member of its species.  Like most omnivorous, opportunistic, garbage-eating, carrion-savouring creatures deemed pests it has profited admirably from our presence and has extended its range substantially since the mid-1800s.  Originally prolific through Central and South America, it has since expanded across the Rio Grande and through Florida via some helpful idiot.  It can’t go much farther north, but it’s spread from Texas to Tennessee.   They eat all manner of burrowing insects and invertebrates, small amphibians and reptiles, and carrion, thus giving them terrible breath.  Sometimes they’re hunted for their habits of eating eggs, sometimes for their apparently pork-like taste. 
The nine-banded armadillo is the state mascot of Texas as of 1995, and can most often be found there lying dead besides a highway.  Some Texans objected to this decision.

 

Black Caiman (Melanosuchus niger).

Caiman babby.  Note that it is, in fact, a member of the Alligatoridae.

Caiman babby. Note that it is, in fact, a member of the Alligatoridae.

Most caiman species max out around nine feet and a bit.  The black caiman reaches the 14.5 ft. length of the larger American alligators on average and the big fellows can hit 16 ft. – and those are just the known quantities; there’s talk of bigger still lurking somewhere out there in the Amazon river.  Speaking of which, it’s found all over the Amazon basin – or was, before someone realized its hide was valuable.  Now it’s fairly rare and treated as such.  Like most large crocodillians it’s pretty much the apex predator of its zone, capable of ignoring or even eating the anacondas and jaguars that prey upon its young and other, smaller caiman species.  They’re likely dangerous to humans, but given the quantity of black caimans left, let alone the number of larger males (the usual suspects), it’s not really an issue at this time.  Besides, the Amazon has plenty of other ways to kill you.  16-foot caimans are just overkill when a poison frog or a random, horrifying disease will do. 

 

Nile Crocodile (Crocodylus niloticus).

NOT AN ALLIGATOR.

NOT AN ALLIGATOR.

The best way to enter the Old World is to meet one of its most notorious killers, shake it politely by its foot, realize about 0.01 seconds afterwards that cross-species communication does not work that way, and be messily devoured.   The Nile crocodile has killed more people than God, more than any other crocodile (who as a group kill and eat more people than any other animal), and when it goes for you, like most good crocodiles, it does it because it is hungry.  No mistaken identity needed.  No provocation wanted.  It is hungry, and you are perfectly viable as food.  Like almost everything else within arm’s reach – Nile crocodiles will eat things up to giraffe size, eat leopards and lions if they’re getting hungry, and at maximum adult size (11-16 ft. average, old males can reach over 18 ft.) there is nothing on the continent that will try to go for them.  As with any crocodillians they begin small, and they’ll still eat fish even as adults, but their first preference is always large prey – something Africa still has plenty of, in spite of all we’ve done for it.  Sadly, much of said large prey is also us, and the Nile crocodile has a bad habit of living in and around water that people would rather like to use for other things.  After vigorous hunting from the 1940s to 1960s it’s been prevented from a full bounce-back by pollution, accidental fishing net entanglements, and annoyed people with rifles who don’t want to be eaten.  This is more of an issue than it sounds, since like any good apex predator, removing the crocodiles from the ecosystem shakes things up badly all the way down to the roots as whatever they’ve been eating booms like a post-war baby. 

 

The Pink Fairy Armadillo (Chlamyphorus truncatus).

These are not alligators, crocodiles, or caimans.  And they're especially not alligators.

These are not alligators, crocodiles, or caimans. And they're especially not alligators.

The teeniest of all armadillos, the pink fairy armadillo (or “pichiciego”) lives in central Argentina, where it spends its time burrowing rapidly through loose soil, dirt, and sand, eating invertebrates, averaging 3.5-4.5 inches in length, and being as cute as the dickens.  Their incredible tininess and ability to quickly dig a hidey-hole make knowing anything about them an absolute bitch, even if they’re endangered or not.  We don’t even know precisely what effect cattle ranching has had on their home territory, but who cares because they are eensy-weensy adorablewho’sagoodarmadilloden?!  Yesyouare!

 

Gharial/Gavial/Indian Gavial (Gavialis gangeticus).

Don't stare at it.  It's a fully functioning crocodillian adult and you should treat it like one.

Don't stare at it. It's a fully functioning crocodillian adult and you should treat it like one.

The gharial’s ancestors split off from the rest of the Crocodillians in the late Cretaceous, leaving the gharial (and its close personal relative the false gharial/malaysian gharial/tomistoma) the only surviving members of the Gavialidae family.  Upon separation, the gharial’s ancestors did what anyone else would’ve done and grew a really long goony-looking jaw to grab and spear loads of fish with.  Unfortunately, now it can’t eat anything larger than a fish unless it’s already dead – anything more exhuberant than a corpse is liable to injure those spindly little jaws and snap off needle-teeth.  They’re timid and also the second-largest of all crocodillians, mostly due to their absurd length (12-16.5 ft. average, 20 ft. lengths not unheard of in the slightest).  Its fishy diet is part of an evolutionary package deal: the gharial has become the clumsiest of all crocodillians on land, unable to even raise itself off the ground fully for a rapid walk, but it’s easily the most maneuverable and speedy in the water, with an overdeveloped and laterally flattened tail that gives it great propulsion. 
The wild population of gharials in India is estimated to be something like 1,500, with around 400 breeding pairs.  They’re under threat from pollution, accidental death, and the occasional idiots with weaponry who can’t tell them apart from the smaller, more feisty Mugger crocodiles

 

The Saltwater Crocodile (Crocodylus porosus).

Don't be fooled by its apparent docility.  It is NOT AN ALLIGATOR.

Don't be fooled by its apparent docility. It is NOT AN ALLIGATOR.

The largest of all living crocodiles, the largest of all living reptiles, and one of the most human-unfriendly predators on earth, ladies and gentlemen, the “salty.”  The only thing that prevents this titanic (13-18 ft. average, 20 ft.+ in mature males perfectly fine!) bruiser from racking up a body count that’d make the Nile crocodile blush is its territory, which overlaps much less with humans – it can be found spread across the Western Pacific, much as if someone had buttered it with scaly predators; it has no issues with ocean travel and does so regularly, something hinted at in its name.  It’s also the most sexually dimorphic crocodile existing, with females averaging 9-11 ft. and the record-bearer being a relatively paltry 14 ft.  As a final anatomical peculiarity, it’s much thicker and broader than any other crocodile, giving it a similar body profile to an alligator. 
Once it hits 4 metres or so in length utterly nothing will attempt to give a salty trouble on a regular basis, and only the largest sharks or members of its own kind would even consider it.  The bigger males are effectively invulnerable, and any attempt at listing their diets would be better off listing what isn’t on their menus, either regularly or opportunistically.  Here’s a version of that off the top of my head: whales, Indian elephants, and Indian rhinos.  Obviously it doesn’t make a habit of going for dangerous game (like tigers) regularly, but when you don’t have any issues with crushing an adult water buffalo’s skull in one bite, the world is pretty much your oyster. 

 

Giant Armadillo (Priodontes maximus).

The giant armadillo lives across the easternness of South America in all manner of habitats nowadays, and can also be found as far south as northern Argentina, where it is legally and biologically an alligator.  They average 62 lbs and roughly 3 ft. in length as adultigators.  Mostly feeding upon termites and ants (the mounds of the former are veritable feasts), it isn’t shy about eating larger prey, like mice and rats and those alligators that are younger than itself.  Its larger size has led it to not fare as well as its relative, the nine-banded armacaiman, and it is considered to be endangered, a fate it shares with almost every other extant species of crocodillian worldwide. 
It’s an alligator, you know.

On Kitties.

February 3rd, 2010

I’m going to give you all a brief, merciful break from my terrifyingly awkward fiction to give you a tour of my horribly rambly nonfiction.  Today’s subject, in addition, is one which I’m less than well-versed in, yet something we all enjoy: KITTIES! 

OHMIGODIT'SAKITTEH!

OHMIGODIT'SAKITTEH!

Except we’ll be looking at all the kitties that are big enough to kill and eat you. 

Nummy.

Nummy.

Admit it, it’s more interesting that way.  We’ll be doing this in order of rough body size, because that’s the way real manly insecure men do things. 

The Cougar/Catamount/American Lion/Mountain Lion/Puma/Panther (Puma concolor)

Mountain_lion

Yes, that’s all just one species.  Cougars are the largest cats in North America (115-198 pounds for males 64-141 lbs for females, 60 to 76 centimetres at the shoulder).  In the incredibly informal lumping of the Felids (the taxonomical Family of the KITTIES, in case you were an ignorant lout and didn’t know this – hence, “feline”) into the twi groups of the “big cats” and “small cats,” cougars are technically “small cats” – the requirements aren’t size, but membership in the high-falutin’ and exclusive genus of Panthera.  A more literal interpretation of “big cat” adds in the cougar, snow leopard, and cheetah, but that’s newfangled and therefore for those tiresome young people that keep yapping on about saving the whales. 
Cougars are solitary, bar when they’re raising their kittens, which, of course, are extremely adorable (a solitary cat – my GOODNESS GRACIOUS AND BEANS).  They’ve lived over almost every inch of both the Americas, from tip to top, although now for some strange reason totally unconnected with testy land-hogging plains apes with gunpowder weaponry they’re inexplicably scarce across a lot of their former range.  In particular, the Eastern seaboard is pretty cougar-less – a far cry from the old days (which hasn’t stifled the odd sighting or sign of them – there may very well be mountain lions about there again, if in small numbers.  That reminds me of the time what possibly could have been a cougar studied our cat with avid curiosity from about thirty feet away in our backyard before idly trotting away, but hey, back to the topic at hand here….KITTIES). 

The most adorable cases of bed head you're ever likely to see.

The most adorable cases of bed head you're ever likely to see.

Being as far-ranging as cougars are (or were) naturally means flexibility, with regards to habitat, food, and just general adaptiveness overall.  They eat deer, birds, small mammals, bighorn sheep, cattle, horses, even a moose now and then or insects – whatever there is lying about at the time.  This requires a fair amount of individualized learning and experience; dump a South American cougar into the Yukon, and it would be highly puzzled on meeting a moose.  Nothing really returns the cougars the favour – bears, wolves, jaguars, alligators and caimans alike may share the top predator position, or even exceed the cougar’s claim, but they don’t particularly seek out and eat them as a matter of course.  As a rule of thumb, few predators enjoy the prospect of hunting down something that’s very likely to hurt them, and other apex predators are seldom meek and willy prey.  Speaking of which and turning back to the point above, cougars are fairly unlikely to go for humans – they rely on learned prey recognition, something that usually isn’t formed for us in particular.  They’re most likely to attack if they’re starving or feel threatened – and even then,  they prefer to go for children, with their usual method of downing prey: a bite right in the neck.  Attacks like that are almost always fatal.  Scientists say it’s probably because of the canines severing your spinal cord, or your vertebrae crunching, or windpipe collapse, jugular spurting apart, or something else sciencey like that. 

 

The Leopard (Panthera pardus)

The leopard would like to tell your cats that sleeping on pillows is for wussies.

The leopard would like to tell your cats that sleeping on pillows is for wussies.

The smallest of the “big cats” of Panthera, the leopard is part of an exclusive club – this older, more restricted definition of the group is also deemed the “four who can roar.”  That’s right, outside the Panthera big cats, not a single kitty can roar (although they scarcely need that to alarm you – cougars have a scream that resembles a woman’s, just the thing to put you to sleep on a lonely night in the wilderness).  Speaking of the cougar, despite occupying opposing continents, the leopard isn’t all that different from it in quite a few ways – it’s lean rather than bulky, and it’s approximately the same size, maybe a little bigger (45-80 centimetres at the shoulder, 82-200 pounds – for males, which are about 30% bigger than females).  They can also produce runty, messed-up hybrid offspring called pumapards, but back to the leopard here.  Its legs are a tad stubby for its body length (to keep from getting tangled up in branches and such), and it’s got a pretty powerful and massive set of jaws on it for its size.  This, incidentally, works well with its after-hunting strategy, where it often drags deceased prey up a tree for safe keeping – the only cat known to do this, and all the more impressive when you realize some of the things it eats are up to thrice its weight.  If you find a gazelle dangling from some branches somewhere, go away before you piss off its owner.  They’re even more far-ranging than cougars, and can be found from Subsaharan Africa all the way into Southeast Asia in scattered populations. 

Note that leopards have never once used different levels of melanin as an excuse to eat each other.  I'm just saying.

Leopards share with jaguars an interesting little habit of occasionally cropping up melanistic rather than spotted – or, to put it more plainly, black.  It’s most common in rain forests and mountainous areas, where it possibly allows slightly better blending-in.  “Black panthers” like these are still spotted, but it’s very hard to make out the markings against their darkened “un-spotted” fur.  On a more humanitarian note, leopards are less likely to go for humans than their larger neighbours, but when they do (via those good ol’ pair of reasons: age or injury forcing them to easy prey) they are regarded as absolutely terrifying – smaller and stealthier than lions or tigers, but just as dangerous and much, much bolder, thinking nothing of waltzing straight into a settlement and yanking someone out in the middle of the night. 

 

The Jaguar (Panthera onca)

Regal, with a touch of staring-right-through-your-skull.

Regal, with a touch of staring-right-through-your-skull.

The third largest kitty on the planet, the jaguar gets a bit less publicity than the lion and tiger (hey, the three biggest cats live on three different continents – there’s some shallow and meaningless meaning there).  It’s got a lot of variation in size – females are 10-20% smaller than males, which meander from 67-76 cm at the shoulder on average, and weights can vary from scrawny (80 lbs) to average variation (124-211 lbs) to as big as a female tiger or lion (350 lbs!).  A large part of it seems to be regional – jaguars from along the Mexican Pacific coast are around as big as cougars, but those in parts of Brazil average over 220 pounds and elder males can end up over 300 lbs without being freaks. As to body build, jaguars are quite different from the svelte and agile cougars and leopards we’ve examined thus far – they’re built thick and powerful, with additional appropriate words being “robust,” “stocky,” and “compact” (unacceptable phrases include “midgetized,” “badger-like,” and “thicker than mother’s oatmeal”), which makes them good swimmers and climbers in the rainforests of South America.  Its bite is incredibly powerful, and if adjusted for body size may be greater than any other felid’s – which may have something to do with its habit of noshing on turtles now and then, to say nothing of armadillos, caimans, and occasionally even an anaconda or two. 

Tip: those cute little prickles on your cat's tongue are meant to be used to scrape meat directly from the bone.  And knowing is half the creep-out.

The Jaguar’s killing method is also noteworthy – no other kitty uses something quite like it.  They take their prey’s head in those big crusher jaws of theirs, and then bite right into the brain – something that’s thought to have a connection with cracking turtle shells.  They tend to use this most often on mammallian prey – but no need to fear.  Of all the big cats, the jaguar has the least human deaths on its conscience, and all of those are either from aged and near-helpless specimens that couldn’t catch anything else or aggressive self-defense.  A final note on its patterning – jaguars, unlike leopards, have small spots inside their “rosette” markings – and leopards have rounder and smaller rosettes. 

 

The Lion, or “The King of Beasts” according to twits (Panthera leo)

When smugness and utter boredom collide.

When smugness and utter boredom collide.

Definitely the most well-known and overrated of all the big cats, the so-called “king of beasts” is only the second-largest, although it’s the tallest at the shoulder.  It’s also among the most visually distinctive, thanks to the impressive manes the males sport.  Unusually for kitties, lions are social animals.  Size-wise, males meander from 330-550 lbs, females 264-400 pounds, with shoulder heights of 4 foot and 3 foot 6 inches respectively.  As is becoming common, these measurements depend largely on environment – both local habitat and global location.  Other notable lion characteristics include nice long canines (8 centimetres), strong legs, burly jowly jaws, tufted tails (unique among kitties), and oh yeah, that huge honking head of hair the males get.  Lion manes make them look much more intimidating when confronting hyenas or each other, but they also make the males as well-camouflaged as a bowl of white rice and tofu in a candy factory.  This is why the big lazy bastards let the females do all the hunting for them.  AND THEN THEY REFUSE TO LET THEM EAT FIRST. 

Adorable as they seem, this lioness and her cub are trapped in an abusive, one-sided relationship.

Adorable as they seem, this lioness and her cub are trapped in an abusive, one-sided relationship.

The exact target of the lioness’s hunts varies, again, with region, but lions in general eat mostly large mammals – they’re big animals, and most of the time they’re hunting not just for themselves and their fellow huntresses but for those big, selfish, greedy chauvinist pigs back home too.  They tend to avoid prey outside the weight range of roughly 420-1210 pounds – smaller, and it’s often not worth hunting, bigger, and it’s liable to get very dangerous – but there are exceptions to this.  The lions of Kruger National Park go for giraffes quite often, and the lions of Chobe Park in northern Botswana make a virtual habit out of going for the park’s elephants – the largest concentration in Africa.  Apparently they started resorting to calves when times grew tough, then moved on to adolescents and even adults, all done at night, when they can’t see it coming as well as they should. 
Whatever they’re hunting, lionesses are usually in wide-open areas with good sightlines, making it essential that they work together to bring down prey that could very well see them coming.  The favored execution method of lions is suffocation via clamping those big jaws around something’s windpipe and slowly throttling it to death, unless it’s small enough to have its spine swatted apart.  Few creatures can return the favour; spotted hyenas have high dietary overlap with lions and are often in competition with them, but lions are simply too big to be bullied unless they’re alone – rather rare for a social species.  Leopards, cheetahs, and African wild dogs are even more easily dismissed, bullied, and occasionally eaten.  The one predator on the African continent that can make a lion wary is a Nile crocodile; a lion might be able to handle one out of the water, but it’d be a rare and stupid crocodile that’d let itself be caught so easily, and it’d better be a small one.  A lion that’s unfortunate enough to run into a crocodile in its element is very unlikely to make it out alive. 
As a final note, lions are indeed more than willing to eat humans – provided the motivation is there.  Again, the old saw of “if-it-is-sick-or-injured” comes into play, but more important yet may be the amount of prey available.  If humans are moving into the area, and humans and their livestock are now more prevelant than bush species, then hey, what do you think the lions are going to eat?  As said previously, lions won’t hesitate to modify their diet according to regional peculiarities, and if this particular peculiarity is “there’s no more wildebeest and lots of chattering plains apes,” so be it. 

Oh, and when a male lion takes over a pride, he often kills all the cubs so the females get horny again and can have HIS kids rather than some other guy’s.  You know what?  This asshole deserves the title of King of Beasts.  Perfectly. 

 

The Tiger (Panthera tigris)

Despite what you may know about cats, tigers like water.  See where stereotypes lead you?

Despite what you may know about cats, tigers like water. See where stereotypes lead you?

The tiger is both the largest cat of all and possibly the most visually distinctive – fie upon your manes, they have magnificently striped sides!  Body size varies wildly – there are seven remaining subspecies of tiger, ranging from the (relatively) “small” Sumatran tiger (220-310 lbs for males, 170-240 lbs for female – an adaptation to Sumatra’s dense forests) to the positively enormous Siberian tiger (males 43 inches at the shoulder and 420-670 lbs, females 220-370 pounds).  Tigers could be found all across Asia before the 19th century, but nowadays they’ve vanished from Western Asia and aren’t exactly numerous anywhere, even their most favored of old stomping grounds.  Their most distinctive features are extremely powerful legs that let them bring down animals much larger than themselves, and of course, their stripes, which tend to average somewhere around one hundred an animal. 

Tiger stripes can break up their outlines against a forest or long grass quite nicely.  Although the middle fellow there doesn't seem to be impressed.

Tiger stripes can break up their outlines against a forest or long grass quite nicely. Although the middle fellow there doesn't seem to be impressed.

Tigers hunt like most big cats – stalking and then pouncing, with massive bursts of speed that can only last for a brief time.  Water buffalo, deer, tapirs, gaur, and all manner of large prey are brought down like a lion – neck-biting and slow suffocation.  Smaller prey typically has its neck bitten, or possibly a whack with a paw – which can crush the skulls of cattle with one shot.  Other predators for the most part stay the hell away from tigers – even crocodiles won’t chance a confrontation often, and tigers are more at home in the water than any other kitty.  Sloth bears can harass adolescent tigers, but adults prey upon them with ease, wolves have been found to steer clear of tiger territory, and the dhole (or “red dog”) of India, while occasionally capable of mobbing a tiger over food in big groups, usually does so only at risking losing massive numbers.  Even brown bears fare no better than fifty/fifty against Siberian tigers in Russia, with the two species stealing kills and young from each other, and occasionally Siberian tigers there will actively prey even on adult bears.  You know you’re dealing with a hardcore predator when now and then it will decide it wants to eat a mature brown bear. 
Tigers are responsible for more human deaths than any other cat, but show no real preference for humans as prey whatsoever.  Most man-eating tigers are sick, old, have broken teeth, or some combination of the above.  In some cases, it’s believed sufficient exposure to the concept via human carrion can cause tigers to register people as “food, of a sort.”  Interestingly enough, man-eating tigers are among the most timid of all man-eating big cats – seldom venturing into villages or settlements, and almost never going for anyone that isn’t alone.  Even something so trivial as being spotted before an attack can be made may be enough to forstall them.  This in no way has prevented them for racking up truly epic individual bodycounts – and in one case, the bengal tigers of the Sundarbans, an entire population of tigers is noteworthy for using humans as a secondary food source.  Theories on their renowned tetchiness range from having to constantly drink saltwater to inability to properly mark territory due to constant flooding to habituation towards human flesh thanks to frequent death tolls from hurricanes and tsunamis in the region.  Plus, the Sundarban tigers are approximately 500 in number, and are one of the largest single tiger populations in the world, which is a high density of large, aggressive kitties. 

 

Things we’ve missed include cheetahs, lynxes, bobcats, wildcats, ocelots, and much more.  Ah well, I’m sure they’ll turn up in good time. 

 

OH SHIT THEY’RE RIGHT BEHIND YOU.

On Bears: Alternative Pronunciation: "Bahres."

January 12th, 2010

It’s been too long since the three people reading this were subjected to another vague, unspecialized, layman’s lecture on animals.  Sadly, I run lower and lower on fuel with each I deliver, so you lucky sods are going to be privileged enough to hear me mindlessly repeat the exact same information I gave you in the bear attacks article.  Yes, you have my permission to yell “woo,” and maybe stick your hands in the air as if you just do not care.  Don’t say I’m not kind to you. 

Bears are members of the Ursidae taxonomical family, with their closest living relatives being the members of the superfamily Pinnipedia – the earless seals, eared seals, and the walrus, which is left out of both groups and made fun of for having funny teeth. 

There is nothing funny about these teeth.

There is nothing funny about these teeth.

Note the family resemblance.

Note the family resemblance.

Bears are mostly omnivores, bar the giant panda (which eats bamboo, and is in danger of extinction) and the polar bear (which eats meat, and is rapidly becoming endangered).  Aside from these two, the rest are pretty much willing to eat whatever, possibly for fear of being next on the line.  Bears as a group share the following traits:

  1. Furry.
  2. Bulky.
  3. Like daylight for the most part, though if they’re raiding trash cans they’re smart enough to go for them at night. 
  4. Mostly live in the northern hemisphere, except for the African Atlas bear (which we shot to death) the South American spectacled bear and Andes bear, and the Southeast Asian sun bear (none of which we’ve shot to death – yet). 

At any rate, it’s time to move onwards and upwards.  We’ll start off with a local favorite. 

American Black Bear (Ursus americanus)

The graceful, roman nose of a black bear's profile is best appreciated when wedged inside your backpack looking for Snickers bars.

The graceful, roman nose of a black bear's profile is best appreciated when wedged inside your backpack looking for Snickers bars.

Well known as by far the most populous and generally widespread bear (or bahre, if you should so deem to call it) of North America, the black bear is both timid and tiny compared to the other local American: the grizzly.  So, as said previously, it’s unlikely to attack you unless it’s trying to kill and eat you – a very encouraging thought, particularly since, like the grizzly, it mostly gets along on roots, berries, nuts, bugs, fish, eggs, and whatever else it feels like eating, such as that tasty, succulent pile of garbage some idiot camper carelessly left lying around.  As a rule people prefer their bears timid and afraid of humans and therefore less likely to hang around their houses cozying up to them, something that’s hard for even the humblest of black bears to maintain when they’re scarfing our leftovers out of a camper or a car or a dumpster every evening.  This gives one more excellent reason to be a responsible twit about your garbage, as opposed to an irresponsible twit, because those end up being the subject line of an article that contains the phrases “lacerations” “mauled” and “habituated” several times too many to be comforting. 

 

Brown Bear (Ursus arctos

In formerly soviet territory of Kodiak, Alaska, teddy bear hugs YOU.

The brown bear is all over the place.  Northern Eurasia, northern America – you name the vaguely chilly upper half of a continent that comes in close proximity to the Arctic circle and it’s there.  As such, it varies quite a lot from place to place, especially on size.  Bear bulk is already highly variable due to the issue of what time of year you’re weighing them (hibernation mass and all that), to say nothing of food supplies (coastal brown bears get so much good fish-food out of it that they outpace their landbound pals by a remarkable amount), but brown bears cover so much land that they’ve splintered into a beautiful grumpy, hirsute rainbow of bear subspecies that can range in number from ninety to five, depending on who’s asking.  Genetically, however, they’re all quite similar.  Size-wise, they can range from the Syrian brown bear, which isn’t much bigger than a black bear, to the alarmingly enormous Kodiak bear, which loses to polar bears in the “world’s largest land-based carnivore” competition solely on grounds of its decadently omnivorous lifestyle (also, although thinner, polar bears tend to be a bit longer and lankier). 

Brown bears are overall more aggressive than black bears, seeing as they’re large and usually can’t climb trees, thus removing one line of defensive options and replacing them with “intimidate the epidermis out of anything that seems to threaten me.”  So although brown bears (PARTICULARLY grizzlies) tend to go for people a lot more than black bears, a much greater percentage of the incidents are based around displaying how much bigger their bearsticles are than yours, and thus are free of predatory intent.  Though this doesn’t preclude you getting eaten. 

 

Giant Panda (Ailuropoda melanoleuca)

A panda pondering its inability to get it up.  Every day of its life is like this, plus bamboo-binging.

A panda pondering its inability to get it up. Every day of its life is like this, plus bamboo-binging.

The panda bear gets much hate – or at least disdain – for its famous lack of willingness to screw even when its entire species is on the line.  Well mister smartass, let’s see YOU get raised in an alien environment surrounded by completely alien creatures and then get shoved into a room full of monitoring devices with a member of the opposite sex.  You feel like getting it on?  Do you?  I thought not. 

For all this, the Panda HAS bounced back quite a bit from its most desperate straits, and it’s getting a bit better at the whole “breeding” thing.  They work out in terms of mass and size to be around the same size as very small brown bears, although they’re much less crotchety.  Still, don’t hug them.  Those claws are there, the muscles exist, and even though they only really eat bamboo, that doesn’t mean they’ll turn down fresh protein if it falls in their path.  It’s mostly just bamboo, though – and since they aren’t running the most efficient plant-matter conversion gut in the world, they have to eat a lot of it.  A lot.  No, more than that.  Like, tons.  Constantly.  Incidentally, the giant panda has a modified bone on its paw that creates a “thumb”-like protrusion, and has the second longest tail of all bears – four to six inches, as opposed to the epic 6-7 inch length of the Sloth bear.  Hah, bet you thought you were going to get through this article without useless number-based trivia, didn’t you?

Polar Bear (Ursus maritimus)

Despite their predatory instincts, polar bears love cubs, especially ones that aren't theirs, because those are edible.

Despite their predatory instincts, polar bears love cubs, especially ones that aren't theirs, because those are edible.

The polar bear is the largest land-based carnivore in the world, so long as you discount the omnivorous Kodiak.  Come to think of it, since polar bears can be quite comfortable over two hundred miles from land and can doggy-paddle at 6 mph comfortably for the entirety of it, perhaps they should be in the marine predator bracket, in which case they lose out to saltwater crocodiles, Nile crocodiles, many large sharks, killer whales, sperm whales, and a bunch of other things.  Well, better a disputed title than none at all.  They’re still the largest bears.  Unless you count the Kodiak’s tendency to be slightly heavier and stubbier – but look, it’s close enough, okay?  Quite being such a prick. 

Polar bears are exceptional in many other ways – for one thing, they live in one of the earth’s harshest environments, yet still manage to find enough fuel to keep that big furry body efficient.  There’s only so much heat loss you can cut out with the ol’ “shrink the size of the ears and thicken the fur” and so on, and a big body helps trap all that warmth inside your big guts, where it can’t escape.  Still, that means you also have to find food to allow that big body to grow into maturity and keep ambling around with all those guts in it.  Polar bear seal hunting involves long, long, long patient waits at ice holes found by the lingering traces seal’s terrible breath, followed by very quick bursts of violent skull-clubbing and yanking the seal up and out of the water.  Even if the hole’s too small for the seal.  Eurgh. 

When it comes to humans, polar bears have none of the timidness of black bears and none of the surliness of browns.  They’re confident.  Of course, there’s decent odds they’ll kill you, but they’ll usually do it because they feel like eating something rather than tetchiness.  Although this may be because very seldom is anything stupid enough to get in their faces and annoy them.

Damnit.

October 21st, 2009

The following three things happened today:

-I started work on a rambling little essay about bears.  Then I found out that I couldn’t upload pictures for some reason, presumably because of some maintenance that’s coming up in the next week. 

-I gave up on that and started scraping together the first bit of a short story I’d got an idea for last night.  I got two thirds of a page in and flatlined, realizing that it would need both (A) lots of research on something I barely understand and (B) an actual plot. 

-I frantically, furiously hunted through my documents swearing like an inebriated linguist and hoping that I’d written something two years ago that wasn’t absolute pus on toast that I hadn’t already used.  I hadn’t. 

So….. to get about a roundabout way of saying it, this is my first official “I screwed up and didn’t manage to give you a single worthwhile thing all week” post.  No doubt this will turn into a slippery slope of pathetic down-the-drain derailment that ends in me posting something bimonthly to apologize for not posting.  Or it will encourage me to start actually going over what I’m going to put up on Wednesday BEFORE Wednesday arrives.  Whichever. 

I leave you with two things: My apologies, and the links to a pair of webcomics that are vastly more entertaining than anything I ever put up here. 

The Adventures of Dr. McNinja (Absolute absurdity.  Where else can you have a storyline involving a clone of Benjamin Franklin that makes perfect sense?).

Gunnerkrigg Court: (General excellentness.  Art starts off much rougher than it ends up being).

Again, I’m sorry.  I’m lazy, but this really shouldn’t be happening.


Film at Eleventeen.

October 14th, 2009

Good around twoish in the morning.  I’m Joey H. M. S. Fishlips and this is OMG’s Not Really News: gathered, semidigested, and regurgitated to the viewer with all the love of a mother seagull.

Our headliner tonight is not so enormously huge, gargantuan, gigantically jumbo-sized large that we’re going to drag it out to the last possible second.  Don’t say we don’t do anything for you, loyal viewers.  In the meantime, content yourself with the knowledge that you do not share the same fate as congressman Herman Bach, who yesterday threw out his entirely fictitious back in a staggeringly bad case of pun-related injury.  “I’ll never be able to look the public in the eye again,” mourned the ironically named and newly hunched Bach, who was promptly booed off the podium by humour critics.

A triumphant conspiracy hasn’t been revealed, and we’re the first on the scene: NASA has admitted that it did, in fact, fake the lunar landing conspiracy theories.
“It was just for a bit of a laugh,” claimed former astronaut Buzz Aldrin.  “We all had a few brews after the medals were handed out, I mentioned we couldn’t believe we’d done it, and then Neil said “Yeah, who would?” and the whole idea just spun itself out from there.  We were going to stage this big prank on April Fool’s day where we sent in a truckload of faked-up mail claiming the whole thing was a hoax, and we were about halfway there when some clerk found all the letters in the storeroom we were using and sent them all at once five months early.  We figured it’d blow over fast – it was too ridiculous to believe.  I didn’t expect it to get so out of hand.  I ended up having to punch a guy who took the whole thing seriously, for chrissakes.”  Buzz, who did not conduct this interview, then punched our reporter Jerry McMahon in the face, although he apologized afterwards, claiming it was “instinct.”  Jerry said it was all right, or possibly swore eternal vengeance; it was hard to tell given that he was now missing 83% of his teeth.

A sports article: the 2010 Vancouver Olympic Games will apparently radically reformat the Games’ traditional setup.  Rather than opt for the “ancient and decrepit” method of running many singular events for different sports and skills, the Olympic officials have decided to simply place every contestant in a very large varied-terrain arena with all of their equipment and give the gold, silver, and bronze medals to “Whoever comes out on top.”  Critics have noted several flaws with this dynamic, such as potentially reducing the actual games to being three times as brief as the opening ceremony (rather than the current twice as brief) and granting unfair advantages to certain competitors, citing such hypothetical examples as an entire national hockey team clashing with a single snowboarder.  The committee’s response has been to “grow some balls already and go for the gold,” as well as the encouraging reminder that the minimum requirements to snowboard are one leg and half an arm.

Turmoil has struck Hollywood, as five separate celebrity couples announced sudden marriage on the same day, dividing the attention of the tabloids so deeply that many of them split down the center and reproduced via cellular mitosis, creating “daughter cells” that are only half the size but can still support a camera and microphone while yammering intrusive questions.  Still, this was a stopgap measure at best, and all five couples immediately annulled in disgust at the poor press coverage.  Two of the women involved have been rendered pregnant by each other’s former husbands, in a twist so staggeringly contrived that they have admitted to planning the whole thing out beforehand as a script pitch.  None of this actually happened, but I wouldn’t be surprised if it did.

The world completely fails to reel in fear at the news of yet another fictional and potentially deadly virus – North American snorkle-fever.  Perhaps this one will succeed at becoming an actual pandemic where SARS, the Asian bird flu, and swine flu have all failed.  Pathologist Doctor Dirk Diddler hypothesizes that the previous epidemic hopefuls became unsuccessful shut-ins due to a severe lack of “badass” in their naming.  Citing the “black death” and “scarlet fever” as his examples, Dr. Diddler forcefully encourages the importance of strong PR in any deadly pathogen’s success.  When asked about the remarkable historical success of the diminutively titled “smallpox,” Dr. Diddler ate his own beard in a paroxysm of rage and grief before committing honourable suicide with his PhD on global television, a move that was widely approved of by his proud parents.  “We always knew he would go far,” claimed Theresa Diddler, looking fondly upon the eviscerated remains of her eldest son and ruffling his bloodsoaked hair.  “And what a way to go.”  Theresa’s other children, Llyod and Doberman Diddler, are a famous tree bark salesman and an anti-animal-rights activist respectively.  Doberman himself hasn’t made news with his declaration to hunt whales “Solely out of pure spite” and armed with firehoses filled with maple syrup, intending to clog the whale’s blowholes with the delicious liquid.  Failure was attained immediately after the pre-launch pancake breakfast, during which the entire ammunition supply and one crewmember’s turtleneck sweater were consumed inadvertantly.  Doberman, when asked for comment, belched forth a hairball the size of an infant’s head.

A substance has been discovered that could revolutionize the global economy by replacing silly putty, experts in Los Alamos claim.  The semisolid, termed “Mucusplex” by its creators, is more than twice as elastic, packs four hundred percent more snugly into a plastic eggshell, and has the exciting and new trait of tending to violently explode when compressed above a certain arbitrary and constantly fluctuating limit.  The research team was scheduled for an interview, but this is invalidated by our next news item, which is the mysterious vapourization of all of Los Alamos.  A exhaustive CIA investigation successfully concluded that this incident was, in fact, under the jurisdiction of the FBI, who subsequently arrested and convicted a nearby local farmer for excessive belching.  He was executed four seconds ago, and his last words were reportedly a heartfelt confession of his illicit and passionate lust for herpes-afflicted carp.

And now our colossal, epic, mega-sized, absolutely false towering news item: France, Belgium, and Rhodesia have fused into a single collective mass of sentient matter, transforming into a five-dimensional shape so elaborate that to look at it unscrews your eyeballs from your sockets and places them delicately in your underwear.  Though rendered above the scope of mortal thought, the entity was still able to communicate in five brief skits of “charades,” each beautiful enough to send hardened tobacco-chewers into sobbing, spitting fits of joy.  Roughly translated, it is currently tapping into the alleged “life-soul” of the entire planet, which it will use to “bring the death of a thousand camemberts upon the false-planet, the asteroid, the contemptible lesser” in a manner deemed so complete and utter that “he will have never existed nor un-existed.”  Earth’s first reaction has been to mourn the overpoweringly sorrowful loss of chocolate and cheese that has stricken us today.

This has been OMG’s Not Really News.  I’m Joey Fishlips, and if you or anyone you love should suffer a tragedy, I will be happy to point and laugh at you if it is sufficiently entertaining.

On Bear Attacks.

September 23rd, 2009

Since we don’t have enough articles on this site about members of the animal kingdom attempting (or succeeding) to maim, mangle, maul, and murderize you, I shall press on. That said, I make these because I am deeply fond of the animals in question, and although the idea of being too close to them scares the pants right off me (fortunately, I am wearing shorts). So don’t get all freaked out and be all “RABBAH RABBAH RABBAH KILL ‘EM ALL FNARGLE SNARGLE WURGH” because then you sound like a cross between a talk radio host and donald duck, and no one wants that. Look at it this way: everyone knows at least one person who they wish would get mauled by something large. So just keep quietly in mind any dangerous locations I mention, and pass them on as holiday destinations.

"Applies to the whole of Svalbard" indeed.

"Applies to the whole of Svalbard" indeed.

We’re going to be looking at three kinds of bears here: brown (mostly grizzly), black, and polar, because they are the most likely to grab someone by the leg and give them a few good clawings.

Black Bears

Yes, those ears are hard to take seriously.

Yes, those ears are hard to take seriously.

Ursus americanus is the smallest and most abundant of the three species we’re looking at, black bear males are 155-600 pounds to the female’s 90-400, and can stand from five to seven feet when upright. How absolutely tiny. And they’re absurdly strong for their size, like all bears, so don’t expect any lucky breaks here. Fortunately, black bears are also easily the most retiring and shy of this trio. Fight or flight? Flight please.

Grizzlies

O BEARLY?

O BEARLY?

Ursus arctos horribilis gets its less-than-flattering subspecies title from George Ord mishearing “grizzly” (as in its grizzled hairs) as “grisly.” Whups. A subspecies of brown bear, the Grizzly is widely regarded as one of the most over-the-top aggressive bears out there, even among brown bears, who are renowned as somewhat tetchy. Size and weight vary on location, from smallish in the Yukon to huge on the Alaskan peninsula, giving a wide range of weight from 300-1000 pounds for males (with a rough average of 500-750), with standing heights of 6 and a half feet to 8 foot. In short: do not mess with them.

Polar Bears

So cute, and yet so unhuggable.  Paradox, thy name is bear.

So cute, and yet so unhuggable. Paradox, thy name is bear.

Ah, Ursus maritimus, the “sea bear.” The largest carnivore in the world, sharing the title of “largest bear” with the Kodiak brown bear, and by far the most hardcore meat-eater of all the bears. Screw the berries, it has seals. Males range from 770-1,500 pounds and are 7.9-9.8 feet in length,with females at half the weight and 5.9-7.9 feet. They’re not as shy as a black bear or as absurdly touchy as the grizzly. But they’re much more likely to look at you and think “Hmmm! That looks like meat! Which is food!”

Bear attacks, like shark attacks, have wildly varying motivations, and these become more or less common depending on what type of bear you’re looking at – for instance, a black bear is much less likely to beat the crap out of you for violating its personal space than, say, a grizzly. So let’s examine a few MOs.

My personal space bubble has been punctured, and now so has your liver

If you can see this, you're probably too close.

If you can see this, you're probably too close.

Being too close to a bear can have varying effects. It may back off, run away, stand its ground, not care, or go ballistic and beat you up until you cower on the ground like the pathetic waste of flesh that you are. Grizzlies are by far the most likely perpetrators of this sort of thing, being as touchy as they are. The running theory is that since they’re too large to climb trees quickly and easily (unlike black bears), they decided the best defense was a good offense. If you trigger this sort of assault, the best idea is probably to play dead, which has a good chance of making the bear realize you’ve admitted your puniness and causing it to back off – the root of the old “if it’s a brown, fall down” advice-rhyme.

Cuteness is next to deadliness

Look, but don't touch.  And you'd better look from far, far away.

Look, but don't touch. And you'd better look from far, far away.

Bear cubs are absolutely adorable, and no one knows this more than their mothers. Which makes them very, very protective. Bear reaction to getting too close to their cubs varies – black bears will chase them up a tree and stand guard, grizzlies and polars will probably charge – but they all seem to have a similar response to getting between the mother and the cubs, which is to go absolutely ballistic. Remember that major sexual dimorphism bear females suffer from? It won’t actually matter at this point. Male bears 33%-50% larger than the females aren’t stupid enough to bug them with their cubs (which they often think look awfully nummy), so why should you be? Your response should be the same as when you infringe on its personal space: play dead to show that you are far too pathetic and feeble to do anything mean, and that you are really, really, really, really sorry and don’t plan on bugging it again.

I’m hungry, you’re here, let’s deal

See that salmon?  Don't be like it.

See that salmon? Don't be like it.

As similar for sharks, actual, deliberate predation is the rarest type of attack a bear can make, as well as the most deadly.  Bears usually need to be either very used to humans or very hungry to give it a shot – the former is why you shouldn’t be feeding them, leaving delicious-smelling food all around a campsite, or letting them hang around a garbage dump all day. Grizzly bears, despite having a very large attack record, are more likely to attack you because (again) of their immense tetchiness rather than hungry.  Polar bears are primarily predators, unlike their omnivorous pals, so they’re more likely to actually try to kill and eat you if they’re attacking. And black bears, although incredibly unlikely to attack you at all, are probably trying to eat you if they do. It makes sense if you think about it: if black bears are shy enough that they usually run away from you when confronted, then attacks are almost always going to be the result of either separating the mother and cubs or active predation. This, by the way, is the root of the other half of the advice-rhyme, which is: “if it’s a black, fight back,” which also sounds something you’d hear in a KKK nursery.

The Following Things Are Surprisingly Unlikely to Kill You.

September 16th, 2009

Following up on the theme of some weeks back, here we are with a brief contrast and follow-up to my earlier ramblings on things that will kill you horribly. Now let’s try looking at some things that SEEM like they would do that, but actually won’t. Usually. Bear in mind that almost every single form of life on the planet will try to screw you over in some way should you try to mess with it, be it through bite, claw, or smush.

Timber Wolves

Bad hair day.

Bad hair day.

Not nearly as dangerous as you’d think from all the werewolf legends and so on. You can count unprovoked attacks by non-rabid wild wolves in North America on the fingers of one hand, after that hand has been mangled by a wolf suffering from rabies. Without major habituation, rabies, provocation, rabies, serious injury, rabies, severe starvation, or rabies, they’re usually pretty timid about people, even in groups. Which doesn’t mean that wandering up to apex predators and trying to give them cuddles is any less unsafe and stupid, and would most likely be filed under “provoked attack.” It’s worth noting that North American wolves seem to be more timid than the world average – Russia and India have plenty of wolf attacks recorded right up to the present, and Europe has tons and tons of stories about wolves going for people back in the old days, although you can expect plenty of historical distortion there.

Almost Every Species of Shark Ever

The cutest mindless eating machine ever.

The cutest mindless eating machine ever.

Okay, maybe harmless is pushing it a bit.

Okay, maybe harmless is pushing it a bit.

440+ different species, ranging from open-ocean fish eaters to reef-dwelling shellfish-scarfers to coastal seal-chompers. And out of all of them, only the Great White, Tiger, Bull, and possibly Oceanic Whitetip make attacking people anything close to a habit. And the rest? Most of them are totally harmless due to specific diets, live so far out of the way that they never meet a human, are tiny, or are all three. The few that are big enough and aggressive enough to make a go at a human….usually don’t. We just aren’t really that palatable as fish food, and we’re large and weird enough that most sharks don’t feel like experimenting. Exceptions can be made for people bleeding all over the place/waving glittery fish-scale like objects/splashing frantically like a wounded fish/carrying around wounded fish/invading a shark’s personal space/trying to poke the shark just to see what happens. In most of these cases the shark will just check the situation out and vanish without ever being seen, or bite you once as a warning/to see exactly what’s going on before realizing its mistake.

Black Bears

Aren't you the cutest little - wait, where's your mother?

Aren't you the cutest little - wait, where's your mother?

When black bears attack someone, they almost always attack with intent to kill. Even with their position as the grizzly’s little brother, the males still average over 200 pounds and 6 foot when standing erect, and unlike us they aren’t relatively scrawny and feeble for their size. So why are they on this list? It’s because they’re shy as hell and, on face-to-face meetings with you, will likely run away farther, faster, and first. The reason most black bear attacks are made with predatory intent is because they almost never attack as a means of defense – running is much higher on their response list. Therefore, a great proportion of black bear attacks will be purely predatory, even though they’re astronomically unlikely to try and attack you for food in the first place. Grizzlies, on the other hand, are touchy louts who react to personal space issues with violence, inflating their recorded attacks. Demean not the noble black bear with tales of this villainy, for he will graciously depart from your presence almost immediately, reacting with alarm to your clumsy ways.*

*Warning: said description does not apply if the bear is starving/old/sick and just trying to eat you/has you directly between her and her cubs/you are trying to feed it/it’s been habituated by constantly eating people’s garbage/are hemming it into a tight corner/are trying to pet it and hug it and love it and name it “Archibald.”

Pythons and Boas

Isn't that the cutest little face?  Go on, give him a hug!  He loves hugs!

Isn't that the cutest little face? Go on, give him a hug! He loves hugs!

Constrictor snakes tend to be far too small on average to actually take down humans for the most part, and show a general lack of desire to do so in general, preferring rats and so on. To kill an animal, they loop around it really quickly and squeeze tighter against its ribs on each exhalation, constricting until the victim can’t inhale and suffocates. You’re most likely to see someone killed if they’re raising them as pets and get careless while home alone. The Green Anaconda (a type of boa, pictured above) and the Reticulated Python are the two top contenders for size, with the python most likely longer (around 30 feet is the estimated maximum) while the anaconda is probably heavier (around 550 pounds). Both could be considered dangerous enough that you really shouldn’t go near them in the wild, but then again, you probably guessed that. They’re still far, far, far less likely to put a crimp in your day than one of their venomous cousins. Just don’t try to cuddle them. That would be silly.

Going Swimming Less Than Half an Hour After Eating Even After Mother Told You Not to Because You Are a Rebel at Heart.

Unacceptable.

Unacceptable.

Eating and then partaking in exercise is always uncomfortable. Eating and then swimming will not, however, give you immediate crippling cramps that will plunge you into a watery grave in paroxysms of agony, according to all known records of lifeguarding and such. Because that’s just silly. While we’re at this, your mother lied to you about Santa too. AND the Easter Bunny. Don’t even get me started on the Tooth Fairy.


On Sharks Yet Again: The Six Million Dollar Fish.

September 2nd, 2009
It is time once again to wander back to my most excruciatingly over-described topic. I’d get more creative, but I’m in the deep and terrible thrall of a cold, courtesy of my sister.

“But what’s left to say?” you might not ask, so I will ask myself for you. “We’ve already covered shark attacks, dangerous sharks, and several hideous photoshop’d lolsharks!” “Why, but the shark’s senses, Jamie,” I tell myself in the condescending voice I use for friends and relatives. “You should know about this already, you shallow and insufferable twit.” I laid myself out after this with an enthustiastic yet inept punch to my frail, porcelain-like jawbone, so I can’t recall the rest of that conversation and the following article may become incomprehensible in places where my brain damage in leakeds.

Electroreception

This chart, sadly, contains no pie.  Imagine one for yourselves.

This chart, sadly, contains no pie. Imagine one for yourselves.

Since we’re going alphabetically, first up on the list of shark senses is one that we don’t have any equivilant for, because we suck. Jelly-filled tubes in a shark’s face (the Ampullae of Lorenzini, named after the guy who first really took a look at them in the 1700s) detect electrical fields in the water. How sensitive are they? They can detect muscle contractions. Go from this to the fact that the heart is a muscle, and if you’re close enough a shark will notice you based solely on your heartbeat. That’s pretty impressive, and in fact sharks may be the most electrically sensitive animals on the planet. It’s extremely possible that they also use the Ampullae to find their way around the world, sensing the planet’s magnetic field and electrical currents within the oceans – a useful trick for any species that wander around a lot.

Hearing

It'll hear you coming.  But it only loves you for your spearfishing.

It'll hear you coming. But it only loves you for your spearfishing.

Shark hearing tends towards good. Higher-pitched noises give them difficulty, however – the upper registers of our hearing are completely soundless to them. Screw that crap. This is the ocean, not some namby-pamby surface world. We use LOW-PITCHED sounds here, and we like it, and sharks hear those like a cat hears a can opener. They can hear very low noises with incredible accuracy for several miles…. such as those emitted by something splashing into the water, or a fish struggling in distress. No, I’m not deliberately trying to add a sinister bent to each and every capability, why do you ask?

Sight

Jeepers creepers, where'd you get those peepers.

Jeepers creepers, where'd you get those peepers.

Being underwater all the time makes sight slightly less useful than it is in the crisp, clean (well, nowadays smoggy and filthy) air of landbound critters. Still, shark eyes are good, and (naturally) can see better underwater than a human’s. They can see you before you even know they’re there okay I’ll stop now. Anyways, shark eyes. The more durinal the shark is, the better its eyesight, the more nocturnal, the worse (harder to see at night and all that). Daytime active hunters tend towards the best eyesight. All sharks possess the tapetum lucidum, a reflective layer of tissue behind the eye that bounces light entering it back outwards, allowing improved night vision. Cats and dogs possess it as well – visible in cameras and at night as “eyeshine.” That’s right, shark eyes glow in the dark sorry I said I’d stop that. Many sharks possess a sort of eye-covering lid called the nictating membrane, which flips over their eye when they’re doing something that might hurt it, like mangling flailing prey. However, some, like the great white, don’t have this. Instead, to protect their vulnerable eyes when biting, they roll them back in their sockets, turning them from all-black to all-white (permission to shiver slightly granted) and relying on their other senses to land the kill.

Smell

Don't laugh; it works.

Don't laugh; it works.

Ah, smell. The most famous shark ability, the ol’ “able to find a single drop of blood in an olympic swimming pool.” Truth be told, fish guts have always excited sharks more than blood under testing, but it’s still no exaggeration. Sharks have phenomenally keen noses, and that above swimming pool line is a fancy way of saying “one part blood per million seawater.” This nose leads them to prey over very large distances, as well as sewege outlets. Now you have one more reason not to swim near them – no need to thank me. By the way, the odd head shape of hammerheads, as seen above, is thought to provide a sort of extra platform for scent – making it very easy to determine smell direction by testing which nostril the scent is in, swinging the head back and forth as you swim. It’s also supposed to provide a broader platform for the Ampullae of Lorenzini, for much the same reasons – hammerheads are particularly adept at finding buried rays made completely invisible by hiding in the sand.

Lateral Line

Note how line-like it is.

Note how line-like it is.

Yet another sense our feeble bodies don’t possess, but this one is scarcely unique to sharks – fish in general have it, as well as a few other marine organisms. The lateral line’s function can best be summed up as “ranged touch.” Groups of hair cells surrounded by jelly form “neuromasts,” which sense vibrations and movement in the water around them, arranged in, well, a lateral line down each side of the shark. They have a much longer sensory reach than the shark’s electroreception, and their hair cells bear a curious resemblence to those in the inner ear, hinting at a common origin. It might also let sharks tell if big chunks of low pressure – like say, a hurricane – is coming towards them.

I could mention taste and touch, so I will. The shark’s mouth tastes stuff, and also touches stuff, because the rest of the shark is covered in thorny dermal denticles (skin-teeth, or tiny little spiky bits that make a shark’s skin aquadynamic sandpaper). So if a great white grabs you in its mouth, it might just be seeing what the hell you are. You can’t fault curiosity.
