This species is distinguished from other European gobies by the following characters: body slightly laterally compressed, anterior part is neither significantly wider nor flatter than caudal peduncle; head length 25-30% SL; no scales, granules, tubercles on body, but with 2-3 wide dark bars; no cephalic lateral line canals; D1 V-VII, with posterior extremity of its membranes reaching origin of D2; ; D2 with 11-13.5 branched rays; caudal peduncle about 3 times longer than deep; eye diameter about 20% HL; interorbital distance smaller than eye diameter; ventral part of second bar narrower than its middle part (Ref. 59043).
Occurs in lower reaches of rivers, deltas and estuaries; over muddy sand with shells (Ref. 4696). Eggs are pear-shaped (Ref. 4696). Feeds on benthic invertebrates, rotifers and algae (Ref.59043).
