Office in Kielce ul. Piranhas are "basically like regular fish with large teeth". Although generally described as highly predatory and primarily feeding on fish , piranha diets vary extensively, [3] leading to their classification as omnivorous.
Piranhas lay their eggs in pits dug during the breeding season and swim around to protect them.
Newly hatched young feed on zooplankton, and eventually move on to small fish once large enough. Piranha teeth are often used as tools themselves such as for carving wood or cutting hair or to modify other tools such as sharpening of darts.
This behavior has been documented among several South American tribes, including the Camayura and Shavante in Brazil and the Pacahuara in Bolivia.
They are often considered a nuisance by fishers since they steal bait, eat catches, damage fishing gear and may bite when accidentally caught.
Piranhas can be bought as pets in some areas, but they are illegal in many parts of the United States, and in the Philippines , where importers face six months to four years in jail, and the piranhas destroyed to prevent proliferation in the latter.
The most common aquarium piranha is Pygocentrus nattereri , the red-bellied piranha. Piranhas can be bought fully grown or as young, often no larger than a thumbnail.
It is important to keep Pygocentrus piranhas alone or in groups of four or more, not in pairs, since aggression among them is common, not allowing the weaker fish to survive, and is distributed more widely when kept in larger groups.
It is not uncommon to find individual piranhas with one eye missing due to a previous attack. Although often described as extremely dangerous in the media, piranhas typically do not represent a serious risk to humans.
Most piranha attacks on humans only result in minor injuries, typically to the feet or hands, but they are occasionally more serious and very rarely can be fatal.
Various stories exist about piranhas, such as how they can skeletonize a human body or cattle in seconds. These legends refer specifically to the red-bellied piranha.
A common falsehood is that they can be attracted by blood and are exclusively carnivores. When former American President Theodore Roosevelt visited Brazil in , he went on a hunting expedition through the Amazon Rainforest.
While standing on the bank of the Amazon River, he witnessed a spectacle created by local fishermen. After blocking off part of the river and starving the piranhas for several days, they pushed a cow into the water, where it was quickly torn apart and skeletonized by a school of hungry piranhas.
Roosevelt later described piranhas as vicious creatures in his book Through the Brazilian Wilderness.
