简单描述 检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 7; 背的软条 (总数) : 8 - 9; 臀棘: 1; 臀鳍软条: 8 - 9. This species is placed under Hyrcanogobius on the basis of slightly different organization of cephalic sensory pores (Ref. 59043).
This near-pelagic coastal marine species is found in areas with different salinities, including freshwater. It lives for a year and matures at 18-20 mm SL. Spawns after first winter, May-June, down to 2-7 m, with females probably laying 2-3 portions of eggs (0.4-1.0 mm), separately attached inside a mollusc shell; and adults dying soon after spawning. Feeds on small crustaceans (Ref. 59043).
