Piranhas are "basically like regular fish with large teeth". [19] A few other species may also occur in large groups, while the remaining are solitary or found in small groups. [3] Although popularly described as highly predatory and primarily feeding on fish, piranha diets vary extensively, [3] leading to their classification as omnivorous. [4]
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 ...

Megapiranha is an extinct serrasalmid characin fish from the Late Miocene (8–10 million years ago) Ituzaingó Formation of Argentina, described in 2009. [1] The type species is M. paranensis. [2] It is thought to have been about 71 centimetres (28 in) in length and 10 kilograms (22 lb) in weight. [3]
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]
