Narrator: and now itโs time for some more amazing animals number 68 the amazing red-bellied piranha this is the red-bellied piranha found in the amazon and other rivers in south america itโs got a bit of a reputation for me no iโm nice hmm well they have been described as the most ferocious freshwater fish in the world oh thatโs nonsense you see the red belly piranha has a voracious appetite for fresh meat they take chunks out of their prey with their razor sharp teeth and donโt even swallow excuse him oh derek even though they are small pound for pound some piranhas can actually bite harder than a great white shark usually feeding in large groups or schools they locate their prey by scent or motion scientists believe the red-bellied piranha can actually talk to each other sadly they donโt seem to have sounds that say donโt eat that or iโm tired letโs get take out yes theyโre scary but the red-bellied piranha is still one amazing animal.
