Espinas dorsales (total) : 7; Radios blandos dorsales (total) : 8 - 9; Espinas anales: 1; Radios blandos anales: 8 - 9. This species is placed under Hyrcanogobius on the basis of slightly different organization of cephalic sensory pores (Ref. 59043).

Biología     Glosario (por ej. epibenthic)

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).
