臀鳍软条: 11 - 12. Head very broad (width 28-31% SL, 96-109% HL); body dark brown marbled or with narrow vermiculations, and low and anteriorly truncate first dorsal fin. Distinguished from highly similar species Cottus hispaniolensis by the following characters: pelvic fins hyaline or with faint brown marks; low and anteriorly truncate first dorsal fin; last dorsal-fin ray connected to body by a membrane along 1/3-2/3 of its length; last anal-fin ray not connected to body by a membrane; and fewer lateral line pores (31-32+1). Differs also from other Cottus in Atlantic drainages by the following characters: caudal peduncle stout (length 14-18% SL, depth 8-10% SL and 1.5-2.1 times in its length); no prickling in adults, a few prickles under pectoral fin in juveniles; eye diameter 20-25% of HL; interorbital distance 1.1-1.4 times in eye diameter; no membrane between last pelvic-fin ray and body; membranes between pelvic-fin rays wider distally (Ref. 55856).
头部非常宽的;(宽度 28-31% SL, 96-109% HL) 身体深褐色的有大理石花纹或者有狭窄的蠕虫爬迹形的装饰 , 与低与前面截形的第一背鳍。 与高度相似的种 Cottus hispaniolensis 区分了藉由跟随特征: 腹鳍透明的或有模糊的褐色标志; 低与前面截形的第一背鳍; 连接到身体的最后背鳍鳍条经由一个膜沿着它的长度中的 1/3-2/3; 最后的臀鳍鳍条不连接到身体经由一个膜; 而且较少的侧线孔 (31-32+1). 在特征之后也不同大西洋的流域的与其他的 Cottus 藉由: 尾柄矮胖的 (長度 14-18% SL, 深度 8-10% SL 與 1.5-2.1 倍於體長); 沒有刺當成魚時, 一些刺在胸鰭下面在稚魚中; 眼直徑 20-25% 的 HL; 眼間距 1.1-1.4 倍眼直徑; 沒有在最後的腹鰭鰭條與身體之間的薄膜; 在腹鰭鰭條之間的薄膜比較寬的末梢部地.(參考文獻 55856)
Inhabits streams with clear, cool, moderate to swift water and stone substrate (Ref. 59043).
