Ecology
Pelagic; depth range 100 - 2000 m (Ref. 96968). Tropical
Indo-Pacific. Tropical to subtropical.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 30.0 cm TL male/unsexed; (Ref. 96968)
Mantle length is 10 cm (Ref. 96968). The upward orientation of the telescopic eyes is used for prey detection. Juveniles appear to occur in shallower water (Ref. 96968). Rare but seen in mangroves (Ref. 101170).
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.
