Just How Hard Do Piranhas Bite? (Video)
A real sharp-toothed threat comes from the rivers, where the piranhas lie. This video shows how hard a piranha can bite, and why you should never mess around with one. These very brave men are testing out the biting power of a piranha by placing what seems to be a twig in its mouth.
That doesn't sound too impressive in itself, but what is astounding is how quickly the twig disappears once it's placed within biting distance. The enthusiastic snaps from the small but fierce fish indicate that it's hungry for more.
