Cosmopolitan in tropical, subtropical to temperate waters. In the South Pacific Ocean the species is common in the mixed waters of the subtropical frontal zone and the sub-Antarctic waters. Adults occupy the upper mesopelagic zone during the day and
then undergo diel vertical migration into epipelagic waters at night: off Bermuda, closing-net studies showed it occurs principally at 375 to 500 m during the day and
ascends to 75 to 175 m at night; in open net studies off the Canary Islands, found them at 400 to 800 m during the day and 50 to 100 m to 200 m at night. The species occurs in the eastern Mediterranean Sea/northern Aegean Sea in the mesobathyal basins (Ref. 97142).

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.
