Environment: milieu / climate zone / depth range / distribution range
Ecology
Bathypelagic; depth range 1000 - 1500 m (Ref. 97142). Tropical
Circumglobal. Tropical to sub-Antarctic waters.
Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 24.3 cm ML male/unsexed; (Ref. 97142)
Overall vertical distribution extends from subsurface waters to depths in excess of 1,000 to 1,500 m. Paralarvae and juveniles up to about 40 mm mantle length occur from subsurface depths to around 400 m, while older animals extend progressively deeper with growth. This ontogenetic descent extends to about 1,500 m where the largest specimen caught to date was a 243 mm mantle length subadult (Ref. 97142).
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.
