Morphology | Morphometrics
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).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00271 - 0.01339), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.4 se; based on diet studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Fec=20 (probably batch fecundity)).
Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
