Did you fail that assignment due to propagating a myth, or did your teacher not actually care about the validity of your claims?I wrote a like 5 page essay about a fish in the Amazon River and can swim up a stream of urine into your penis where it hooks itself in and sucks your blood. I'm not even kidding. Its called a candiru and its kinda frikin scary. It is the only vertebrae that is parasitic to humans. Its has two common nicknames: the penis fish, for reasons outlined above, and the toothpick fish, because of its very small size. It can also make its way into the gill of a fish and suck blood from there.
I would give a link but I'm on my phone. :P
Maybe biggest dicks, but wayyyy smaller balls.humans have the biggest dicks of all primates.
actually, i received a very good grade on the assignment. i didnt mention swimming up a stream of urine as i thought it might be inappropriate for schoolDid you fail that assignment due to propagating a myth, or did your teacher not actually care about the validity of your claims?
They actually don't! Well, I believe there's one species that is an exception but it uses a different form of echolocation... something to do with tongue clicks? I'm not 100% sure. Evolutionary speaking, I'm under the impression that all bats started with echolocation and it was eventually lost in megabats, which may have something to do with their size but most likely has more to do with the fact that they're all fruit or nectar eaters and something so expensive energy-wise isn't as worthwhile as just having a good sense of smell. Microbats have more varied diets. Interestingly, all nectarivorious bats play an important part in plant pollination (along with some birds) and fruit eaters like the HWB are involved with plant dispersal.Wait, so the megabats don't echolocate?
Well, the main reason is that if you're bitten or scratched by a bat in Australia they have to kill it in order to test it for Australian Bat Lyssavirus, which is a close relative of rabies and the only type of rabies-like virus in Aus. It's basically for your own safety and that of the bats to not touch them directly.Why will a bat have to be euthanized? is it easy to crush it's bones or something?
Great facts btw
These 2, in my country, have mix up name. In the North they call the pointy head "Cào cào" and the blunt head "Châu chấu", but in the South it reverse. And my language wikipedia page about these 2 only provide Latin name for the blunt head, not for the pointy head one.What's the Latin/scientific name?
Protip: Wikipedia is a pretty good translator if you use the alternative language pages
Yes, grasshoppers
Oh, deer....Not all things in nature are actually advantageous.
Stalk-eye fly males have stalk eyes that are getting longer, and longer with each generation-- but actually, the males' eyes are ALREADY so long that it interferes with their flying ability (their vision sucks), weighs them down and... well, the long eye stalk is just connected to higher mortality in the flies in general.
Why then are the stalks getting longer?
It's because chicks dig long eye-stalks.
But this "must have a bigger penis" is hardly something reserved to flies (in terms of sexual demorphism). There's a whole species of European deer that went extinct basically because the males had horns that got too big over generations to even lift their head up properly.
Meanwhile, humans are getting taller and taller in recent generations-- and taller still. This despite the fact that height has literally nothing to do with our survival ability/functionality in everyday life, and in fact is related to health problems (once you pass the 7 ft mark). All because chicks dig tall guys.
Just proves how-- in every place, in every time, in every species-- women manage to fuck things up.
In fact, while humans have 3 types of cone cells for detecting colour, Mantis Shrimps have 11 types of cone cells!Mantis shrimp also have some of the most complex eyes in the animal kingdom. Someone else can go into that though.
