Description
The arapaima or pirarucu is one of the largest freshwater fishes in the world, of the family Arapaimidae from the Amazon basin. The species can reach about 4.5 metres and has an elongate, armoured body with large scales and reddish markings on the rear half. It lives in quiet, oxygen-poor waters of floodplains and bank waters and, thanks to a lung-like swim bladder, must regularly come to the surface to gulp air. As a predator it hunts fishes and other prey at the surface. It builds a nest and the parents guard the brood. The arapaima is an important food fish; owing to overfishing wild populations are threatened. It is harmless to humans.
