Description

The Nyong catfish is an African claroteid catfish (Claroteidae) from rivers and lakes of the Nyong drainage in Cameroon. The species grows to about 30 cm and has a sturdy, scaleless, greyish body with four pairs of barbels, an adipose fin and a flattened head. As a nocturnal bottom-dweller it searches over sand and mud for insect larvae, molluscs, crustaceans and small fish. It is locally an important food fish. The stout, serrated pectoral and dorsal spines can give a painful puncture wound when handled.
