Brachyplatystoma filamentosum, commonly called piraíba, kumakuma, or lau lau, is a species of large catfish of the family Pimelodidae and genus Brachyplatystoma that is native to Amazon and Orinoco River basins and rivers in Guianas and northeastern Brazil.[1][2]
Distribution
It is a widespread species that is found in rivers and estuaries of Amazon and Orinoco watersheds, Guianas and northeastern Brazil.[2]
Description
It grows to a length of 2.8 m.[1] The largest Amazon Piraíba records 2 – 2.5 m weighing more than 150 kg.[citation needed]
Dorsum dark to light grey with small dark spots on caudal-fin or peduncle. Dorsal fin with pink shading. Caudal fin deeply-forked. Juveniles exhibit dark body spots or blotches.[3]
It is entirely piscivorous preying on loricariids and other bottom-dwelling fish.[3]
Ecology
Brachyplatystoma filamentosum is found in both freshwater and brackish water systems. The species is a demersal potamodromous fish that commonly inhabits deeper, flowing channels with soft bottoms.[2]
Uses
Though a massive species, Piraíba is considered as a game fish and commercial fish. Generally harmless, it is known to be an obligate piscivore; however, stomach contents are said to include parts of monkeys.[4]
