简单描述
检索表 | 型态特徵 | 形态测量图
臀鳍软条: 11 - 14. Differs from all other European Cottus (except C. poecilopus) by having conspicuously tessellated pelvic-fin rays. Distinguished from C. poecilopus by possessing a single chin pore. Other characters useful to distinguish this species from other Cottus in Atlantic drainages include: caudal peduncle stout (length 14-19% SL, depth 7-9% SL and 1.5-2.4 times in its length); in prickling in adults (juveniles unknown); eye diameter 19-22 % HL; interorbital distance 0.9-1.3 times in eye diameter; last anal-fin ray with membrane connecting to body along 0.5 of its length; last dorsal-fin ray connected to body by a membrane along 0.5-1.0 of its length; membrane between pelvic fin and body on about 1/5 of last ray; membranes between pelvic-fin rays broad but narrower distally; lateral line complete 33-35+1 pores (Ref. 55856).
有别于所有的其他欧洲的 Cottus(除了 C. poecilopus 以外) 借着具有显著棋盘格的腹鳍鳍条。 藉由持有一个下巴孔与 C. poecilopus 区分了。 其他的特征有用的将此种与大西洋的流域的其他的 Cottus 包括区分开: 尾柄矮胖的 (长度 14-19% SL, 深度 7-9% SL 与 1.5-2.4 倍于体长); 在刺当成鱼时 (稚鱼未知) 方面; 眼直径 19-22% HL; 眼间距 0.9-1.3 倍眼直径; 最後的臀鰭鰭條用連接到身體的薄膜沿著它的長度中的 0.5; 連接到身體的最後背鰭鰭條經由一個膜沿著它的長度中的 0.5-1.0; 在腹鰭與身體之間的薄膜大約 1/5之上最後鰭條; 在腹鰭鰭條之間的薄膜寬的但是比較狹窄的末梢部地; 側線完整 33-35+1個孔.(參考文獻 55856)
Inhabits streams with clear, cool, moderate to swift water, and stone substrate (Ref. 59043).
