Ponticola

Ponticola is a genus of gobies native mostly to fresh waters of the Black Sea - Caspian Sea region in Eurasia. Some species occur in the brackish-water Black and Caspian seas themselves.[1][2] It was considered to be part of the broader goby subfamily Benthophilinae, also endemic to the same region, although the 5th edition of Fishes of the World does not list any subfamilies in the Gobiidae.[3] Originally, Ponticola was described as subgenus of Neogobius.
