Stubby squid fin movement (Rossia pacifica) is very interesting to observe. It was great seeing the body fins rhythmically moving against the black backdrop of the ocean during a night dive. In the day this small squid will bury itself in the sediment with just its eyes poking above the bottom to keep a lookout. These cool little animals unfortunately have very short lifespans and live for only two years. The compact stubby squid can reach a length of about 6 inches (15 cm), with a range that includes Japan and Korea to Siberia, as well as northern Alaska to northern Mexico.
