In the world of extreme sports, hippos may be the bravest athletes in existence.
Of course, there's no real winners in the sport of "crocodile licking" so they shouldn't expect a trophy anytime soon.
That's right, one of the hippo's favorite pastime is walking right up to crocs and licking them while they are in a feeding frenzy.
Scientists aren't really sure why they do it. There's no apparent benefit to doing it, and it probably annoys the crocodiles more than helps them in any way.
I guess the hippos just really like being around the hungry, ferocious beasts as they tear their weaker prey to shreds.
The crocodiles can't do much about it—hippos are much more powerful.
They aren't a threat, however. Hippos are vegetarians and have no interest in harming the killers of the swamp at all.
Even baby hippos get in on the "fun" so there really must be something to it.
