Description

The Caucasian dwarf goby is a very small goby of the family Gobiidae reaching about 5 cm. The slender, brownish body has, like all gobies, pelvic fins fused into a sucking disc with which it clings to the bottom; breeding males develop dark cross-bars and yellow tints. The species is euryhaline and lives in brackish lagoons, river mouths and adjacent fresh water of the Black Sea and Caspian Sea basins. As a bottom-dweller it hunts small zooplankton, crustacean larvae and mosquito larvae. It is short-lived; the male guards the eggs laid under a shell or stone. Because of its small size it has no fishery importance, but locally it is numerous.
