Description

The mudfish is a large, eel-like air-breathing catfish of the family Clariidae reaching about 1 metre. 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 water and even crawl over moist ground to new water or wait out drought in the mud. The species comes from much of Africa and lives in rivers, lakes, swamps and floodplains. As an omnivore it eats insects, worms, crustaceans, small fish and plant matter. It is an important food and aquaculture fish, with stout, serrated pectoral spines.
