Common mantle length ranges between 25 and 35 cm (Ref. 3722). In the Mediterranean Sea no individual was caught in the hauls taken above a depth of 100 m (Ref. 81305). However, studies carried out in Norwegian waters indicated that it occurs in coastal and bank areas 80-200 m and even more superficially at 20-100 m (Ref.81307). It was also observed from the North Atlantic Ridge at a depth of 1947 m (Ref. 81308). Maximum depth from Ref. 1985. Demersal, neritic (Ref. 112172). Occurs from the surface to a depth of 2500 m (Ref. 2614). Juveniles feed mainly on fishes while adults consume crustaceans (Ref. 112351). Migrates to offshore waters during winter; spawning is thought to occur in the continental slope (Ref. 2614).
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Members of the class Cephalopoda are gonochoric. Male and female adults usually die shortly after spawning and brooding, respectively. Mating behavior: Males perform various displays to attract potential females for copulation. During copulation, male grasp the female and inserts the hectocotylus into the female's mantle cavity where fertilization usually occurs. Life cycle: Embryos hatch into planktonic stage and live for some time before they grow larger and take up a benthic existence as adults.
