Ponticola bathybius is a species of goby endemic to the Caspian Sea, where it occurs in depths down to 200 metres (660 ft). It is strictly confined to the brackish-water basin and does not enter fresh waters. It can grow up to a length of 25 centimetres (9.8 in) TL.[1]
The species was transferred to the genus Ponticola from Neogobius on the basis of relationship revealed in molecular investigations.[2]
