Russian Sturgeon
Acipenser gueldenstaedtii
Adult Russian sturgeons are large bottom-feeding fish of the Black, Caspian, and Azov sea regions, entering major rivers to spawn. They use four sensory barbels and a protrusible, toothless mouth to vacuum up worms, molluscs, crustaceans, and small fish. Heavy rows of bony scutes protect the body from many attacks. This long-lived species is critically endangered, largely because of overfishing for its roe and river disruption.
