Piranhas are generally less valued, although they are commonly consumed by subsistence fishers and frequently sold for food in local markets.
A few piranha species occasionally appear in the aquarium trade, and, in recent decades, dried specimens have been marketed as tourist souvenirs.
This term is most often used when referring to sharks or piranhas.
This piranha is so voracious to bite and eat everything at the reach of his teeth.
Some of the more famous are the black spot piranha and the cardinal tetra.
Research is being carried out to establish how piranhas have moved to such distant corners of the world from their original habitat.
Piranhas occasionally bite and sometimes injure bathers and swimmers, but serious attacks are rare and the threat to humans has been exaggerated.
In contrast, piranhas long believed to be strict carnivores.
