The black piranha (Serrasalmus rhombeus), also known as the redeye piranha, white piranha, spotted piranha or yellow piranha, is a species of freshwater ray-finned fish, a piranha from the family Serrasalmidae. It is found in northern South America. It is the type species of the genus Serrasalmus.
These ocelli have been suggested to function to limit fin-nipping by piranha (Serrasalmus spp.), which co-occur with A. ocellatus in its natural environment. [ 8 ] [ 10 ] The species is also able to rapidly alter its colouration, a trait which facilitates ritualised territorial and combat behaviours amongst conspecifics. [ 11 ]
While studying piranhas and pacus in an effort to better assess vital fish biodiversity in the 4,000-mile-long (6,400-kilometer-long) river, an international team of researchers has found and ...
Pacu (Portuguese pronunciation:) is a common name used to refer to several species of omnivorous South American freshwater serrasalmid fish related to piranhas.Pacu and piranha do not have similar teeth, the main difference being jaw alignment; piranha have pointed, razor-sharp teeth in a pronounced underbite, whereas pacu have squarer, straighter teeth and a less severe underbite, or a slight ...

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]
