Maximum mantle length is 31cm (females) and 27cm (males) in the northern part of its distributional range, but 20 cm (females) and 18cm (males) in the southern part (Ref. 3722). Feeds on euphausiids, capelin, herring, juvenile mackerel (Ref. 275).
Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | Eggs | Fecundity | Larvae
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.
