The four species of piranha that are carnivorous, however, certainly earn their reputation as fierce fish. These meat-eaters have powerful jaws 1 and razor sharp teeth that fit together like cutting shears 2 when they bite. Piranha travel and hunt in schools of about twenty fish, and can engage in impressive feeding frenzies 3 when aroused by blood or commotion 4 in the water. Carnivorous piranha will eat anything from other fish to large mammals such as cows and even jaguars 5 that wander too far into the water. Although flesh-eating piranhas sometimes attack people, humans tend to have the last laugh. In South America and elsewhere piranha are considered fine eating fish. It’s safe to say that many more piranha are eaten by people than the other way around.
