Distribution of Rossia pacifica in British Columbia in British Columbia


"Stubby squid (or bobtail squid) live from the lower intertidal region down to 300 m deep around the perimeter of the North Pacific from Japan to Southern California." (The Cephalopod Page 2013). In British Columbia they are reported from all along the coast.

Individuals of Rossia have a very stereotyped escape response. It appears to be a response to slow patrolling predators on the bottom fauna, particularly dogfish sharks. The sepiolid lauches from the bottom and swims about 30 to 40 cm above the bottom more-or-less in a straight line inking every few meters. When it should ink the last time, it doesn’t, but it turns dark, throws its arms up in a “scatter” posture and drifts like an ink blot until it hits the bottom, whereupon it bleaches (which makes it effectively disappear) and rapidly covers itself with sediments.
