8 More Kinds of Animal Craziness

What you never knew you wanted to know about animals – but you really do

Episode 2

Did you know that –

Chimps

Are champs at recognizing rumps? It’s not the face, but the butt they look at to tell one buddy from another – and they do it just as easily as humans distinguish faces. Bright colours, it seems, count for both species. In humans, females’ red lips are attractive to males, a fact well-known to lipstick manufacturers. No lipstick for chimp females though. It’s the red rump that’s the big turn-on in chimp society. The redder the better because when the rump blushes even deeper crimson the male knows his lady is ovulating and it’s now or never.

The Mysterious ‘Silkhenge Spider’

In the jungles of Peru and Ecuador, builds a very special protective playpen for its young? In spite of extensive publicity in the world of science, no-one yet knows what species this clever beast belongs to. Watch this video of spiderlets being born, and hear the scientists trying to unravel the mystery

Grizzly Bears

Run fast? So fast they would win the race against that lightning-speedster Usain Bolt himself, no competition. Don’t be fooled by that large lumbering appearance. These beasts can run at 30mph, and that’s just when they’re cruising. If you put them under pressure or make them mad, who knows what their top speed might be? Never try to outrun a grizzly. If Usain couldn’t do it, you and I certainly can’t!

The female shark

Has learned to grow an extra-thick skin? And not because she gets insulted more than most. It’s just that during mating, her male counterpart has the unpleasant habit of biting her – hard. Those jaws are not a thing to be trifled with!

Tarantulas

Are right-handed? At least we think so. Right-handed? With 8 legs, or is that arms? I reckon the Honduran curly hair tarantula deserves a prize for its name alone. And if not for its name, its size. It’s as big as a grapefruit. Eek. It seems more often than not, male curly-hairs choose to take a right turn rather than a left in a laboratory maze, when in either direction there’s the promise of their favourite food, cockroaches. Ditto in pursuit of females. The difference is statistically significant (ie. happens more often than if by chance). “Furthermore, the team observed that the male spiders prefer to use their right eyes and feet while moving.” Not so much right-handed, more right-footed then.

Whatever, there’s no call for alarm, arachnaphobes. It seems this species is pretty docile, unless you’re a cockroach that is. And isn’t he a magnificent beast?

Japanese snails

Are a knockout? Literally. Two snail species of the genus Karaftchelix are said to be “unusually aggressive”. Can you even imagine an aggressive snail? A contradiction in terms, surely. But these ones are veritable Snail Samurai. While most snails in danger retreat into the safe haven of their shell, these two kinds are no shrinking violets. They use their shell not for retreat, but attack – as a weapon of war, swinging it vigorously and very effectively at their predator, the carabid beetle. See the warriors in battle here:

Egyptian fruit bats

Bicker? A lot. They row over food, feud over their favourite spots in the roost, and even have romantic tiffs. And the way they talk varies depending on the particular bat person they are addressing. No different from us then. Before this latest study, scientists thought all that noise was just saying ‘get the heck out of here’, or words to that effect. But after running 15,000 calls through a “machine learning algorithm” (don’t ask – I don’t know) the researchers discovered the squabbling was much more complex than you might expect. And they expect more intriguing discoveries from bat-speak yet to come.

Humans

Used to have a penis bone? Seriously. What is a penis bone? What’s it for, and how come we were so careless as to lose it? It’s scientific name is a baculum, and it’s an ‘extra-skeletal’ bone, which means it’s not attached to the rest of the skeleton, “but floats daintily at the end of the penis”. Again, eek. A variety of mammals have hung on to theirs but ours is not even vestigial like the appendix – it’s gone for good. The scientists have various colourful speculations as to its purpose. And also why our evolution alone among primates found no further use for one. As you may have suspected, it’s all about the mating game. Different species, different mating strategies. Some need’em, others don’t.

I hope you have enjoyed these fun facts. I actually put them together with another more serious purpose in mind. Shouldn’t we marvel at the infinitely fascinating,  colourful, varied and complex life on this planet of ours, and do all that we can to keep it safe? Sadly, new species are being discovered that are already extinct. There is so much we don’t know. So much more to discover and wonder at. Let us treasure it at its true worth which is beyond price.
