    The piranha is a relatively small fish with a round body, large head, and bulldog-like face. Piranhas can grow to between 8 and 15 inches (20-37 cm) long. Piranhas swim in groups called shoals. There are usually around 20 piranhas in a shoal. Although it was once believed that piranhas swim in shoals in order to attack, it is now thought that swimm...

    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. Piranhas come in an array of different colours, including yellow, gray, blue, red, and black. One of the most common species of piranhas is the red-bellied piranha, so named for its reddish belly. Another common ...

    The piranha’s most notable characteristic is of course its set of razor sharp teeth. The teeth are triangular in shape and are used to puncture and tear the fish's prey. 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. It’s no...

    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. Piranha...

    Piranha feeding frenzies occur when there has been a shortage of food and the shoal locates some prey. Sensing blood in the water, each fish in the shoal attempts to tear off a piece of food. When this occurs, the water seems to boil and churn. Piranhas are capable of stripping their prey of flesh in a matter of minutes, and when frenzied, will bit...

    Piranhas are freshwater fish, and are found primarily in South America in the Amazon Basin, the Orinoco River and east of the Andes Mountains. They can inhabit diverse locations such as lakes, tributaries, wetlands and creeks. They have even been found in flooded forests. Piranhas prefer fast-flowing water. They are highly tolerant of many water co...

    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 will bite if it feels threatened or if its eggs are being endangered. Black piranhas and red-bellied piranhas are believed to be the m...

    Piranhas are eaten not only by other predatory fish (including other piranhas), but also by animals such as herons, caimans, water snakes and turtles. Adult piranhas have been known to eat their own young.

    Piranhas lay groups of eggs in larger bodies of water, such as lagoons. The female will lay several thousand eggs in a bowl shaped nest made in the sediment (the material that has sunk to the bottom of the body of water). The eggs are then fertilized by the male and will hatch two to three days later. The piranha parents will defend and protect the...

    Although piranhas can be kept in home aquariums, they do not always make good pets. Owners must be very careful of the piranha’s sharp teeth and aggressive nature. It has been known for people, tired of owning such a difficult pet, to release piranhas into the local waters; this causes a serious danger both to other fish and humans. Keeping piranha...
