The African lungfishes are the
genus Protopterus and constitute the four species of lungfish found in Africa.
Protopterus is the sole genus in the family Protopteridae.
African lungfishes are elongated, eel-like fishes, with
thread-like pectoral and pelvic fins. They have soft scales, and the dorsal and
tail fins are fused into a single structure. They can either swim like eels, or
crawl along the bottom, using their pectoral and pelvic fins. The largest
species reach about 200 centimetres (6.6 ft) long. African lungfishes generally
inhabit shallow waters, such as swamps and marshes; however, they are also
found in larger lakes such as Lake Victoria. They can live out of water for
many months in burrows of hardened mud beneath a dried-up stream bed. They are
carnivorous, eating crustaceans, aquatic insect larvae, and molluscs.
