Europe: Upper Volga, Ural and Dniepr drainages and northern and eastern Gulf of Bothnia in Finland and northern Sweden. Southern Baltic tributaries west to Estonia (Ref. 55856). Cottus populations from Dniepr, Ural and Pechora drainages are tentatively identified as Cottus koshewnikowi (Ref. 59043).

简单描述
检索表 | 型态特徵 | 形态测量图
臀鳍软条: 11 - 14. Can be distinguished from other species of Cottus in Europe by the combination of the following characters: lateral line incomplete; reaching to anal-fin base, usually with 17-25 pores; at vertical of 10th ray of second dorsal fin, lateral line clearly above horizontal midline, distance from dorsal midline to lateral line 1.5-2.1 times in distance from ventral midline to lateral line; no distinct transverse bands on pelvic fin; prickling on body variable, in juveniles usually extending to caudal peduncle (Ref. 55856).
能在欧洲被与其他种的 Cottus 区分藉由下列特征的组合: 侧线不完全的; 延伸到臀鳍基底, 通常有 17-25个孔; 在垂直的第二背鳍鳍的第 10 鳍条, 侧线清楚地在水平的中线之上, 从背部中线到侧线的距离 1.5-2.1 从腹的中线到侧线的倍距离; 没有在腹鳍上的明显的横纹; 在身体上刺可变的, 在通常被延伸至尾柄的稚鱼中.(参考文献 55856)
Inhabits medium-sized rivers to small streams, and lake shores (Ref. 59043).
