Description

The stellate tadpole goby is a strange, tadpole-like goby of the family Gobiidae reaching about 13 cm. The broad, strongly flattened head merges into a rearward-tapering, tadpole-like body; the scaleless skin is studded with bony tubercles resembling little stars, from which the species takes its name. Beneath the chin it carries a barbel. The species comes from the Ponto-Caspian region and lives on sand and mud bottoms of brackish and fresh water in the Black and Caspian Sea drainages. On the bottom it searches for small crustaceans, molluscs and worms. It spawns once in spring, after which the adults usually die. Because of its small size it has no fishery importance.
