Piranhas are small fish with a big reputation — and big teeth! Piranhas are freshwater fish, and live in the rivers and streams of South America.
Do Piranhas Attack Humans?
The idea that piranhas will attack humans is mostly myth. Attacks by piranhas on humans are rare, and most have been exaggerated.
Native people will happily swim in rainforest waters with piranhas present.
A piranha’s teeth are replaced continuously throughout its lifetime. The teeth grow in four sets; one for each corner of the fish’s mouth. Sets are replaced every 100 days.
Despite their reputation of being voracious meat eaters, piranhas are actually omnivores (plant and meat eaters).
Piranhas mostly eat smaller fish, snails, insects, and some aquatic plants. However, they didn’t get their ferocious meat eating reputation for nothing. They will also eat small mammals and birds that have fallen into the water.
There are at least 20 species of piranha – and there could be as many as 60! Scientists are unsure of exactly how many species there are!
