Description

Werner's catfish is an air-breathing catfish (Clariidae) from the fresh waters of Africa. The species has an elongate, scaleless body with a flattened head, four pairs of barbels and a long dorsal fin; it has a tree-shaped gill organ with which it can breathe air and thus survive oxygen-poor water. It inhabits lakes and rivers. As a predator it feeds mainly on insects: aquatic and terrestrial beetles and their larvae. The stout pectoral fin spines can give a painful puncture wound when handled.
