Research on red-bellied piranha breeding behavior in nature has revealed certain behavioral patterns around nesting sites. Adult piranhas will swim side-by-side in small circles, sometimes with two individuals swimming in opposite directions while keeping their ventral surfaces close to one another. Although this may appear to be a courtship ...
The dietary breadth of the wimple piranha is one of the narrowest reported for fishes; scales form an important proportion of the diet throughout most of its life, and adults feed almost entirely on them (see lepidophagy). In laboratory conditions, wimple piranhas are known to feed on scales from fish up to three times their own length, and are ...
Piranhas will often scavenge, [9] and some species such as Serrasalmus elongatus are specialized scale-eaters, feeding primarily on scales and fins of other fish. [3] Scale- and fin-eating is more widespread among juvenile and sub-adult piranhas. [20] Piranhas lay their eggs in pits dug during the breeding season and swim around to protect them.
This characteristic combined with its large size make it a danger to humans. Piranha's attacks on humans are anecdotal for the most part. The piranha mostly prefers to eat small fish and insects, along with seeds and aquatic plant material. The pygocentrus piraya plays a key role in their ecosystem by regulating the population of other fish [5]
A few piranha species occasionally appear in the aquarium trade, and, in recent decades, dried specimens have been marketed as tourist souvenirs. [6] Piranhas occasionally bite and sometimes injure bathers and swimmers, but serious attacks are rare and the threat to humans has been exaggerated. [ 6 ]
From up-close and personal animal encounters like snorkeling with sharks and rays or carefully tong-feeding sea turtles, The Adventure Aquarium is best known for having the world’s longest V ...
Serrasalmus geryi, known as the violet line piranha or Gery's piranha, is a species of piranha of the family Serrasalmidae. It is found in the lower Tocantins and Araguaia Rivers of Brazil . [ 1 ] [ 2 ] The species is notable for being the one of only the members of the genus Serrasalmus that can coexist with others of the same species in ...
Pygocentrus is a genus of the piranha family Serrasalmidae. All species are native to tropical and subtropical South America. All the species are predatory, scavengers and may form large schools. The famous red-bellied piranha, Pygocentrus nattereri, is one of four species in the genus. [1]
