Rossia pacifica原产于太平洋北缘,从日本到加利福尼亚南部,包括白令海峡的极地地区。 他们在冬天在中等深度的沙质斜坡上度过冬天,在夏天度过较深的水域繁殖。 他们喜欢沙质而不是泥沙底部,发现于沿海水域,他们一天中的大部分时间都停留在地表以下50–1,200英尺(罕有1600英尺)的深度。 当他们在夜间狩猎时,会发现它们在海岸线或附近游泳。 他们喜欢生活在主要猎物附近的虾床上,白天将自己挖入沙子,以便只看到他们的眼睛。 当被打扰时,它们会变成乳白色的绿色,并喷出一团黑色墨水(章鱼和鱿鱼墨水通常是棕色),形状像鱿鱼。


Rossia pacifica is native to the northern edge of the Pacific Ocean, from Japan to southern California, including the polar regions of the Bering Strait. They spend the winter on a medium-depth sandy slope in the winter and spend deeper waters in the summer. They like sand rather than the bottom of the sand, found in coastal waters, and they spend most of the day at a depth of 50–1,200 feet (rarely 1600 feet) below the surface. When they are hunting at night, they will find them swimming on or near the shoreline. They like to live on a shrimp bed near the main prey and dig themselves into the sand during the day to see only their eyes. When disturbed, they turn into a milky green color and eject a black ink (the octopus and squid inks are usually brown) shaped like salmon.
