Description

The Nile bichir is a large ancient fish of the bichir family (Polypteridae) from the Nile and adjacent African drainages. The species grows to about 74 cm and has an elongate, snake-like body covered with hard, rhomboid ganoid scales and a row of small finlets on the back, characteristic of bichirs. It inhabits shallow bank and swamp zones, where it likes to lie basking. Bichirs are living fossils that can breathe air with a pair of primitive lungs and so survive in oxygen-poor water. As a predator it hunts, mainly at night, fishes, amphibians, insects and crustaceans. The species is harmless to humans.
