Description

The gray bichir (Polypterus senegalus) is an ancient African freshwater fish of the family Polypteridae, sometimes called the 'dinosaur eel'. The species has an elongate, grey-green body covered with hard, shiny ganoid scales and bears a conspicuous row of separate finlets on the back. It reaches about 70 cm and has a pair of functional lungs, with which it breathes air and survives oxygen-poor water. It inhabits swamps, lagoons and the muddy margins of rivers, where it lies quietly or glides about snake-like. As a nocturnal ambush predator it hunts fishes, insects and other invertebrates. The species is popular in the aquarium.
