Big Fish Piranhas Definition

Piranhas fit in with the subfamily Serrasalminae, which incorporates nearly identified omnivorous fish, for example pacus.traditionally, just the four genera Pristobrycon, Pygocentrus, Pygopristis and Serrasalmus are recognized to be accurate piranhas, because of their particular teeth. 

 Then again, a later investigation demonstrated that, if the piranha gathering is to be monophyletic, it ought to be confined to Serrasalmus, Pygocentrus and part of Pristobrycon, or developed to incorporate these taxa in addition to Pygopristis, Catoprion, and Pristobrycon striolatus.

Pygopristis was discovered to be more nearly identified with Catoprion than the other three piranha genera.
The aggregate number of piranha species is obscure and challenged, and new species press on to be depicted. Gauges go from fewer than 30 to more than 60.
