Argonauta pacifica, also known as the Pacific argonaut, is a species of pelagic octopus.

Rossia pacifica diegensis
Rossia pacifica diegensis is a subspecies of bobtail squid native to the eastern Pacific Ocean off Santa Catalina Basin, California. It occurs at greater depths than its sister taxon "R. p. pacifica".
