وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
الأشواك الظهرية (المجموع) : 7; الأشعة الظهرية الناعمة (المجموع) : 8 - 9; شوكة شرجية: 1; أشعه شرجية لينه: 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).
