Climate / Range
Subtropical; 10°C - 24°C (Ref. 275); 61°N - 48°S, 180°W - 180°E (Ref. 275)
Circumglobal in subtropical and temperate oceanic waters.
Mantle length at first maturity: 29 to 32 cm (male); a little less than 40 cm (female; Ref. 275). Maximum mantle length of females is 90 cm; maximum mantle length of males is 45 cm (Ref. 97142). Caught by dipnets (Ref. 417). Oceanic but occurs near the surface at night (Ref. 417). Occasionally washed up on the beaches (Ref. 88739). 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 (Ref. 833).
