The bichirs are a family, Polypteridae, of archaic-looking ray-finned fishes, the sole family in the order Polypteriformes. They have thick bonelike scales and a series of dorsal finlets instead of a single fin. Their jaw structure more closely resembles that of the tetrapods than that of the teleost fishes. All species occur in freshwater habitats in Africa. They are popular subjects of public and large hobby aquaria.
