Description

The Lake Malawi airbreathing catfish is a large, air-breathing catfish endemic to Lake Malawi in East Africa. It can reach a metre in length and has an elongate body with a long dorsal fin and barbels around the mouth. Like related airbreathing catfishes it can breathe air through a special gill organ. The fish lives at depths between about 20 and 90 metres and is a plankton feeder that sieves small crustaceans from the water, supplemented with small fish, insect larvae and plant matter; it sometimes forages at the surface in groups. It is an important food fish. The IUCN assesses the species as Least Concern (LC).
