context_page_description: Rossia pacifica, also known as the stubby squid, is in the order of Bobtail squid that native to the northern Pacific Ocean. This species has eight arms and two retractable limbs like a squid, while also remaining closer to the ocean bottom similar to the octopus. While the common name may suggest this species is a squid, they are more closely related to cuttlefish. Seen in winter on sandy slopes away from strong currents in moderately shallow water, it moves in summer to deeper water where it breeds. The female cements the egg capsules under a stone or in some other concealed location, and both male and female die soon after breeding.
context_section_description: The stubby squid is a small species growing to a maximum mantle length of about 5 cm (2.0 in) and a total length of 11 cm (4.3 in), with females being larger than males. The head bears eight short arms, a pair of retractable tentacles and two large eyes. The first pair of arms is shorter than the others and the third pair the longest. The arms are circular in cross-section and each bears up to four rows of suckers on the middle section and two rows elsewhere. The tentacles have club-shaped tips with suckers and retract into pits in the head. They can be as long as the body when fully extended. The mantle (body) is not fused to the head and is flattened dorso-ventrally and rounded at the back. It does not contain the cuttlefish bone typical of cuttlefish in the family Sepiidae. There are two large semi-circular fins with wide bases on either side of the mantle. The upper surface of this epic squid is normally a reddish-brown colour with a scattering of small brown or yellowish spots, but can change to greyish-green when the animal is startled.
