Etymology: Cobitis: Greek, kobitis, -idos = a kind of sardine; also related with the voice Greek, kobios, Latin gobius = gudgeon (Ref. 45335).

生態学
; 新鮮な水 底生の漂泳性; 移住性ではない (Ref. 38442). Temperate; 44°N - 36°N, 9°W - 1°W
Europe: Iberian Peninsula, except in Alagon system (Tagus drainage), northern Ebro and northern Douro drainages. Also found north of the peninsula where it has been locally introduced.
初回成熟時の長さ / サイズ / 重さ / 年齢
成熟: Lm 6.1, range 6 - 6.4 cm
Max length : 7.0 cm SL オス/雌雄の選別がない; (Ref. 59043); 13.0 cm SL (female); 最大記録サイズ: 5 年 (Ref. 38442)
Presence of mandibular barbel 4-8 times in HL. Pectoral fin length 4.3-5.4 times in SL in males, 4.3-9.0 times in females. 6-7.5 branched dorsal rays. One lamina circularis.
Body shape (shape guide): elongated.
A short-lived species, secretive in nature (Ref. 38442). Adults inhabit middle and lower reaches, with shallow waters, sandy bottoms and submerged plants (Ref. 11240). During dry periods, they can survive in very small water bodies (Ref. 59043). Feed on invertebrates and plants. Spawn in May to July. Oviparous, with distinct pairing during breeding (Ref. 205). Eggs are small (1.7 mm) and sticky, placed within dense vegetation if available (Ref. 59043). Threatened due to pollution, habitat destruction and the introduction of other species (Ref. 26100).
ライフサイクルと交尾行動
成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
During courtship, 'the male follows the female and, after both enter dense vegetation (e.g. filamentous algae), the male forms a complete ring around the female's body behind the dorsal as the female releases the eggs' (Ref. 59043).
