Benthophilinae
The Benthophilinae are a subfamily of gobies endemic to the Ponto-Caspian region (including the Marmara, Black, Azov, Caspian, and Aral Seas). The subfamily includes about 50 species. The representatives of the subfamily have fused pelvic fins and elongated dorsal and anal fins. They are distinguished from the closely related subfamily Gobiinae by the absence of a swimbladder in adults and location of the uppermost rays of the pectoral fins within the fin membrane. The Catalog of Fishes still considers these fishes as belonging to the subfamily Gobiinae.
