The Piranha (or piraña) is a freshwater fish that normally lives in South American rivers. They are known for their razor-sharp teeth and powerful jaws. They are omnivores, which mean they eat almost anything they can find. Mostly they eat plants, snails, insects, fish but also larger birds and mammals sometimes. Attacks on humans are rare. There are some stories about piranhas eating a person alive but probably in all those cases the piranhas didn’t kill that person; they just ate the remains of a corpse allready there.
