Description

The ship sturgeon is a large sturgeon of the family Acipenseridae reaching over 2 metres. It has a pointed snout with fringed barbels beneath it and, unlike most relatives, a continuous, uninterrupted lower lip. Like all sturgeons it bears five lengthwise rows of bony plates instead of ordinary scales. It is an anadromous migrant of the Black Sea, Caspian Sea and former Aral Sea basins, growing up at sea and ascending the great rivers to spawn. On the bottom it eats molluscs, worms, crustaceans and small fish. Through overfishing for its flesh and caviar, river barriers and the disappearance of the Aral Sea the species has collapsed worldwide and is assessed as Critically Endangered (CR).
