Ecology
Benthic; depth range 3 - 589 m (Ref. 100702). Subtropical
Southwest Pacific.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 54.0 cm TL male/unsexed; (Ref. 96968)
Mantle length is 13 cm (Ref. 122358). Immediately begins to feed upon hatching. Forages at night and hides in rubble or human refuse (e.g. discarded bottles). Primarily feeds on bivalves either by drilling or pulling them apart. Armed with good skin sculpture and camouflage (Ref. 100823).
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.
