Ecology
Pelagic; depth range 0 - 1025 m (Ref. 2123), usually 0 - 200 m (Ref. 2123). Polar; 30°S - 63°S, 180°W - 180°E (Ref. 275)

Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 94.0 cm ML male/unsexed; (Ref. 275)
Reported from the epipelagic zone to deepwater demersal habitats through ontogenetic migration. Females spawn at depths greater than 700m in New Zealand and Falkland Island waters. Reportedly exhibits cannibalism in Falkland Island waters (Ref. 128994).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | 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.
