Europe and Asia: Northern Caspian basin (Volga, Ural).
サイズ / 重さ / 年齢
成熟: Lm ? range ? - ? cm
Max length : 13.0 cm TL オス/雌雄の選別がない; (Ref. 1441); 最大記録サイズ: 5 年 (Ref. 59043)
背面の脊椎 (合計) : 3; 背鰭 (合計) : 7; 肛門の骨: 2 - 3; 臀鰭: 6. Differs from its congeners in Caspian Sea basin by the possession of the following characters: longitudinal epithelial crests on predorsal scales; scale rows around caudal peduncle 14-16; scales on lateral line 42-43 + 2; dorsal fin with 7½ branched rays; and anal fin with 6½ branched rays (Ref. 59043).
Body shape (shape guide): elongated.
Adults inhabit bottom of moderately flowing lowland rivers, preferring sand bottom. Are nocturnal benthic species feeding on insect larvae and other larger benthic invertebrates. Locally threatened due to pollution and river engineering (Ref. 59043).
