Description

The Striped bagrid is a bagrid catfish (Bagridae) from fresh water of East Asia. The species grows to about 20 cm and has a sturdy, scaleless, brown-grey body with four pairs of barbels, an adipose fin and a long anal fin. As a nocturnal bottom-dweller it searches over sand and mud of rivers and lakes for insect larvae, small crustaceans, molluscs and small fish. The stout, serrated pectoral and dorsal spines are venomous and can give a painful puncture wound.
