Max length : 20.0 cm TL Männchen/unbestimmt; (Ref. 13614)
This species is distinguished from other related species in the Black Sea basin by the following characters: pelvic disc 80-100% of distance between its origin and anus; cycloid scales completely cover predorsal area and nape; pelvic disc fraenum with angular lobes, fraenum length 1/6-1/2 of its width at base; scales in midlateral series 58-70 + 2-4; snout length 1.3-1.5 times in eye diameter; first branched ray of second dorsal about as long as penultimate ray; posterior part of first dorsal without black spot (Ref. 59043).
Rarely enters freshwaters (Ref. 26334). Inhabits inshore habitats, brackish lagoons, estuaries and lower part of large rivers; usually associated with rock bottom or sunken trees. Spawns at 2 years, from December to April where females can repeat spawning during a season. Feeds mostly on crustaceans (Ref. 59043).
