Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 33.0 cm ML male/unsexed; (Ref. 104052)
Caught by nets (Ref. 275). Maximum depth from Ref. 1985. Oceanic and elusive. Has little interaction with the bottom (Ref. 106095). Mainly feeds on osteichthyes, followed by crustaceans (natantian), and occasionally on cephalopods. Bases their diet on pelagic nictemeral migrators (Ref. 106992).
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.
