Distribution

Hoplias curupira has an extensive distribution across the north of South America, Venezuela, Guyana, Surinam and Brazil in the Orinoco, Rio Negro (Amazon) and its tributaries, Rio Tocantins, Rio Xingu and Rio Negro (Amazon).[2]

Habitat

Prefers flowing water.

Description

Hoplias curupira are medium-sized but relatively bulky in build compared to other Hoplias with a blunt head and broad body. The colour of the fish changes according to mood from a light brown patterning to an almost solid black colouring leading to the common English name of Black Wolf-fish. In captivity the average size is 40 cm but wild specimens have been reported at up to 75 cm in length.[3]

Habits

Like other members of the genus Hoplias, H. curupira is an ambush predator on various insects, larvae, small fishes, shrimps, worms and fruits[4] and is more diurnal than its cogeners. They appear to live as pairs, defending a territory together.[5]
