Description

The ornate bichir is a remarkable ancient fish of the family Polypteridae reaching about 60 cm. The elongate, brown-yellow body bears a handsome black net pattern and is covered with thick, shiny rhombic ganoid scales - a feature of very old fish groups. A row of separate, spiny finlets runs along the back and the muscular pectoral fins help it 'walk' over the bottom. Notably it has lungs and can breathe air at the surface, letting it survive in oxygen-poor water. The species comes from Central and East Africa and lives along quiet, vegetated margins and swamps. At night it hunts small fish, crustaceans, insects and worms. Because of its archaic look it is popular in the aquarium hobby.
