Maturity: Lm ? range ? - ? cm
Max length : 13.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 1441); 最大年齡: 5 年 (Ref. 59043)
背棘 (總數) : 3; 背的軟條 (總數) : 7; 臀棘: 2 - 3; 臀鰭軟條: 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).
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).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00327 - 0.00767), b=3.17 (3.05 - 3.29), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
營養階層 (Ref.
69278): 3.4 ±0.38 se; based on food items.
Generation time: 1.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
120179): 中等的, 族群倍增時間最少 1.4 - 4.4年 (tmax=5; tm=2).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
