臀鳍软条: 11 - 14. Can be distinguished from other species of Cottus in Europe by possessing a shallow transverse groove in the snout between the anterior and posterior nares and the combination of the following characters: genital papilla lobular in males; depth of caudal peduncle 20-24% HL; length of caudal peduncle 41-64% HL; prickling on body extending backwards to caudal peduncle (reduced or sometimes absent in some populations); absence of distinct transverse bands on pelvic fin; predorsal length 32-37% SL; distance from tip of snout to origin of second dorsal fin 50-52% SL; dorsal head length 21-25% SL; unique molecular markers (Ref. 55856).
Body shape (shape guide): elongated.
藉由在下列特征的前面与后面的鼻孔与组合之间的吻部中持有一个水浅的横跨凹槽能在欧洲被与其他种的 Cottus 区分: 生殖乳突有小裂片的在雄性中; 尾柄 20-24% HL 的深度; 尾柄 41-64% HL 的长度; 在向后延伸到尾柄的身体上刺;(缩小的或有时一些鱼种没有族群) 在腹鳍上缺乏明显的横纹; 前背的长度 32-37% SL; 距离从吻尖到第二背鳍起点 50-52% SL; 头部背面长度 21-25% SL; 独特的分子作记号的人.(参考文献 55856)
Inhabits small streams to medium-sized rivers. Feeds on a wide variety of benthic invertebrates. Females spawn once a year (Ref. 59043).
