Volga dwarf goby

Hyrcanogobius bergi, the Volga dwarf goby, is a species of goby endemic to the Caspian Sea where it occurs in fresh, brackish and marine waters along the coast. Unusual for gobies, this species is almost a fully pelagic fish. H. bergi grows to a length of 3.6 centimetres (1.4 in) SL. This species is also the only known member of its genus.^[2] The specific name honours the Soviet zoologist Lev Berg (1876-1950) who described many new species of goby from the Caspian Sea.^[3]
