Description

The blunt-toothed African catfish is an air-breathing catfish (family Clariidae) of southern and central Africa. The species grows to about 73 cm and has an elongate, scaleless, brown mottled body with a flattened head, barbels and rounded, blunt teeth. It is nowhere especially abundant but is fairly common in weed beds, permanent swamps, quieter waters and on muddy bottoms. With an accessory breathing organ it can gulp air and tolerate low-oxygen water. As a predator it eats fishes, crustaceans and large invertebrates. The species is of commercial value; the fin spines can cause painful injuries.
