Russian sturgeon (Acipenser gueldenstaedtii) swimming along the seafloor of the Black Sea.
The beluga, also known as the hausen (Huso huso), is a large sturgeon that inhabits the Caspian Sea, the Black Sea, and the Sea of Azov.1
Like many other species in the subclass Chondrostei, these fish are migratory; they typically ascend rivers during the spring or summer months to reach their spawning grounds.12
