Info
Rossia macrosoma is among the smallest in the family Sepiolid, he is seldom greater than 50 mm and usually lives at depths of 40 - 50 meters. Although members of the family are commonly known as squid, they are really no "real" squid. They look like a combination between octopus and squid, however, are actually more closely related to the "real" squid. Like cuttlefish, they can dig in the sand. Like octopuses, they keep mostly on the ground up instead of in the open water swim. They are found from the upper intertidal zone to depths of 300 meters.
During the day they bury themselves in sand or mud, only the eyes look out of the sand to watch for predators. They dig a blow by a jet of water under her body in the sand and then throw themselves with two of her arms sand over his head.
They are found in both the northern Atlantic to the Arctic and in the Pacific and the tropical western Atlantic.
In case of mating both animals die, first the male and a little later the female too. The female lays between 25-50 eggs of about 1 cm in diameter on mussel shells, sponges or the underside of overhanging rocks, then it dies. Incubation of the eggs is between 4 to 9 months. The egg capsules must be robust and durable to protect the embryos for so long. Empty egg capsules were kept in running water for six months without any visible decay. The eggs obtained as previously described, no "parental care".
Rossia macrosoma has already been successfully kept in cold-water aquarium (8 - 10 ° C). They feed almost exclusively on live shrimp.
