Description
The Russian sturgeon is a large sturgeon of the family Acipenseridae reaching about 2.3 metres, sometimes more. It has a short, blunt and somewhat upturned snout; beneath the snout hang smooth barbels with which it probes the bottom. Like all sturgeons it bears five lengthwise rows of bony plates instead of ordinary scales. It is an anadromous migrant of the Black, Azov and Caspian Sea basins, growing up at sea and ascending great rivers such as the Danube and Volga to spawn. On the bottom it eats molluscs, worms, crustaceans and small fish. Its roe yields the famous osetra caviar, for which it has been heavily overfished; together with river barriers this has made the species Critically Endangered (CR).
