海洋 居於水底的; 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 雄魚/尚未辨別雌雄; (Ref. 2850)
背棘 (總數): 8 - 9; 背的軟條 (總數): 27-30; 臀棘 0; 臀鰭軟條: 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).
尾鰭圓形的, 方向朝上.(參考文獻 6885) 色彩可變的, 上面灰色的有深色斑紋而且使暗色的條紋陰暗, 腹面灰白的; 刺狀的背部比較深色的; 其他的鰭除腹鰭有斜紋的比較深色的; 有時在有鰭條的背鰭與眼上的紅色的斑紋; 一條非常明顯的黑色條紋斜向下來與經過眼的背面.(參考文獻 6885) 一個可認識的變種出現於騎士小水灣，卑詩省中 - 第一個尾鰭被 2,3 控制, I 而不是前面四個棘與整個的鰭是脆弱的而且當從液體移走顯得更多的起來像一個天線柱一樣勝於一張帆.(參考文獻 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).
生活於近海與對 110 公尺深, 大部份在岩石底部上與有藻類的區域.(參考文獻 2850) 夜行的.(參考文獻 6885) 可能被發現上下顛倒對抗裂隙的頂部.(參考文獻 6885) 以在它的頭部之前被延伸的它的背鰭游泳。 (參考文獻 6885) 卵沈積在冬季末或春天了。 (參考文獻 6885)
