Description

The Guinean bichir is an ancient ray-finned fish (Polypteridae) from fresh water of West Africa. The species grows to about 28 cm and has an elongate body armoured with hard, diamond-shaped scales, a row of separate finlets on the back and strongly lobed pectoral fins. With a pair of primitive lungs it can breathe air and survive in oxygen-poor water. As a nocturnal bottom predator it shelters among roots and plants and hunts small fish, worms and crustaceans. The fish is harmless to humans.
