海洋 居于水底的; 深度上下限 ? - 110 m (Ref. 2850). 溫帶; 66°N - 34°N
Eastern Pacific: St. Lawrence Island, Alaska to San Miguel Island, southern California, USA. Possibly occurring in Japan (Ref. 2850).

Maturity: Lm ? range ? - ? cm
Max length : 20.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 2850)
背棘 (总数): 8 - 9; 背的软条 (总数): 27-30; 臀棘 0; 臀鳍软条: 18 - 20. Caudal fin rounded, directed upward (Ref. 6885). Color variable, gray above with dark markings and obscure dusky bands, paler below; spinous dorsal darker; other fins except pelvic fins diagonally streaked darker; sometimes red flecks on rayed dorsal and on eyes; a very distinct black band running diagonally down and back through eye (Ref. 6885). A recognizable variant occurs in Knight Inlet, British Columbia - the first caudal fin is dominated by the II, III, I rather than the first four spines and the whole fin is frail and when removed from fluid appears more like a mast than a sail (Ref. 6885).
尾鳍圆形的, 方向朝上.(参考文献 6885) 色彩可变的, 上面灰色的有深色斑纹而且使暗色的条纹阴暗, 腹面灰白的; 刺状的背部比较深色的; 其他的鳍除腹鳍有斜纹的比较深色的; 有时在有鳍条的背鳍与眼上的红色的斑纹; 一条非常明显的黑色条纹斜向下来与经过眼的背面.(参考文献 6885) 一个可认识的变种出现于骑士小水湾，卑诗省中 - 第一个尾鳍被 2,3 控制, I 而不是前面四个棘与整个的鳍是脆弱的而且当从液体移走显得更多的起来像一个天线柱一样胜于一张帆.(参考文献 6885)
Occurs inshore and to 110 m depth, mostly on rocky bottoms and areas with algae (Ref. 2850). Nocturnal (Ref. 6885). May be found upside down against roofs of crevices (Ref. 6885). Swims with its dorsal fin extended in front of its head (Ref. 6885). Eggs deposited in late winter or spring (Ref. 6885).
生活于近海与对 110 公尺深, 大部份在岩石底部上与有藻类的区域.(参考文献 2850) 夜行的.(参考文献 6885) 可能被发现上下颠倒对抗裂隙的顶部.(参考文献 6885) 以在它的头部之前被延伸的它的背鳍游泳。 (参考文献 6885) 卵沈积在冬季末或春天了。 (参考文献 6885)
