Description

The Black driftwood catfish is a driftwood catfish (Auchenipteridae) from slow-flowing fresh water of the Amazon basin in South America. The species grows to about 25 cm and has a sturdy, scaleless, dark body with a broad head, large eyes and stiff barbels that it spreads forward at rest. As a nocturnal bottom-dweller it shelters by day under wood, roots and banks and snaps at insects, crustaceans and small fish. The stout, serrated pectoral and dorsal spines can give a painful puncture wound when handled.
