The Guinean bichir (Polypterus ansorgii) is a ray-finned fish from rivers and other freshwater habitats in Western Africa, ranging from Guinea-Bissau to Nigeria.[3] It reaches a maximum length of 72 cm (28 in),[3] is greenish-brown to black in color, and has large, dark spots and blotches on its sides. On mature specimens, the bottom jaw may protrude very slightly. It is similar to some other bichirs with which it can be confused.[2]
