Description

The largemouth catfish is a small African bottom catfish of the family Claroteidae reaching about 28 cm. The brown, smooth body has a broad, terminal mouth, barbels around the mouth, an adipose fin and stout, serrated spines in the pectoral and dorsal fins that can cause painful puncture wounds. The species comes from fresh water of West and Central Africa and lives on soft bottoms of rivers and creeks. Mainly at night it probes the bottom with its barbels for insect larvae, crustaceans, worms and small fish. Because of its hidden, nocturnal lifestyle it draws little notice; locally it is eaten as bycatch.
