Description

The Caspian lamprey is an eel-shaped, jawless lamprey of the family Petromyzontidae reaching about 55 cm. Instead of jaws it has a round sucking mouth; behind the head lie seven gill openings, and pectoral and pelvic fins are absent. The species is an anadromous migrant of the Caspian Sea: the worm-like larvae live buried in the river bottom for years, filtering organic matter, while the adults grow up at sea. In autumn and winter they ascend the great rivers such as the Volga and Ural; in spring they spawn on gravel and then die. Formerly the Caspian lamprey was caught in large numbers. Through dams, pollution and overfishing it has declined sharply and is assessed as Near Threatened (NT).
