Description

The Angolan catfish is an eel-like air-breathing catfish of the family Clariidae reaching about 35 cm. The elongate, scaleless body has four pairs of barbels around the broad mouth and a very long dorsal and anal fin. Like other Clarias species it has a tree-shaped accessory breathing organ above the gills with which it can breathe air, allowing it to survive in oxygen-poor forest and swamp water and even crawl over moist ground to reach new water. The species comes from West and Central Africa and lives in slow water of forest streams, rivers and swamps. As an omnivore it eats insects, worms, crustaceans, small fish and plant matter. It is a valued food fish, with stout, serrated pectoral spines.
