Rossia
''Rossia'' is a genus of 10 species of benthic bobtail squid in the family Sepioidae found in all oceans. They live at depths greater than 50 m (164 ft) and can grow up to 9 cm (3.5 in.) in mantle length. This genus was first discovered in 1832 by Sir John Ross and his nephew James Clark Ross in the Arctic Seas, showing a resemblance to another genus under the same family, '' Sepiola.'' After returning from their expedition, Sir Richard Owen officially classified ''Rossia'' to be a new genus, naming it after Sir John and James Clark Ross. Description ''Rossia'' are categorized under the subfamily Rossiinae, which are identified by their short mantles and lack of ventral shield due to the unextended anterior ventral edge of the mantle. ''Rossia'' are distinguished by their dome-shaped mantles. which are not fused to their head. They are shorter in length compared to many other bobtail squid, with mantle length varying from 1.4 cm (0.5 in) to 9&nbs ...

Rossia Pacifica
''Rossia pacifica'', also known as the stubby squid, is a species of bobtail squid native to the northern Pacific Ocean. It usually occurs in winter on sandy slopes away from strong currents in moderately shallow water. In summer it moves 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. Subspecies Two subspecies are recognised: - * '' Rossia pacifica diegensis'' Berry, 1911 * '' Rossia pacifica pacifica'' Berry, 1911 Description The stubby squid is a small species growing to a maximum mantle length of about and a total length of , 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. T ...

The head is wide, and it and mantle are covered in tubercles which are often large and widely distributed but, in juveniles and as a local variant, they are small and not easily observable. The mantle cavity is divided by a muscular septum. The fins are kidney-shaped and set obliquely. There is often a luminous organ on the ink sac. The tentacles are retractable and have straight, clearly defined clubs. The suckers on the clubs are arranged in about eight rows and are all much the ...

Tentacular Club
All cephalopods possess flexible limbs extending from their heads and surrounding their beaks. These appendages, which function as muscular hydrostats, have been variously termed arms, legs or tentacles. Description In the scientific literature, a cephalopod ''arm'' is often treated as distinct from a ''tentacle'', though the terms are sometimes used interchangeably, often with the latter acting as an umbrella term for cephalopod limbs. Generally, arms have suckers along most of their length, as opposed to tentacles, which have suckers only near their ends.Young, R.E., M. Vecchione & K.M. Mangold 1999Cephalopoda Glossary Tree of Life web project. Barring a few exceptions, octopuses have eight arms and no tentacles, while squid and cuttlefish have eight arms (or two "legs" and six "arms") and two tentacles.Norman, M. 2000.
