Description

The two-dorsal catfish is a large African airbreathing catfish (Clariidae) from West and Central Africa. The species can grow to about 150 cm and has an elongate, scaleless body with barbels and, characteristic of the genus, a second, adipose-like dorsal fin behind the ordinary dorsal fin. Like other airbreathing catfishes it can breathe air with a tree-like accessory organ and so survive in oxygen-poor water. It lives in rivers and lakes and feeds as an omnivore on various animal and plant matter. It is important for fisheries and fish farming. The stout fin spines can give a painful puncture wound.
