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 fish is an omnivore, and has aggressive tendencies when hungry, stressed, or seeking live food. Like most in the Serrasalmidae family, piraya piranhas dental morphology has a major influence for their inclination toward piscivorous and herbivorous behavior [3].
Red-bellied piranhas often travel in shoals as a predatory defense, as well as for the offense. In studies that tested the piranhas' reactions to a simulated predator attack, resting opercular rates returned to normal more quickly among piranhas that were in shoals of eight rather than in shoals of two. Although it has been presumed that ...
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 ...
A man-eating animal or man-eater is an individual animal or being that preys on humans as a pattern of hunting behavior. This does not include the scavenging of corpses, a single attack born of opportunity or desperate hunger, or the incidental eating of a human that the animal has killed in self-defense.
To emphasize the diversity of diets, authors commonly highlight the fruit- and leaf-eating pacus and the highly carnivorous piranhas. Most in the family other than piranhas are primarily herbivorous. In contrast, piranhas have been long believed to be strict carnivores. [4] Many species change diets depending on age and resource availability. [4]
