Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 100.0 cm TL male/unsexed; (Ref. 96968); max. published weight: 2.0 kg (Ref. 275)
A moderate to large species characterized by: 1) water pouches, 2) an arm formula of I.II.III.IV, 3) a rudimentary ligula without a calamus in males, and 4) little apparent skin sculpture.
It's mantle length is 18 cm (Ref. 96968). It is a bottom-dwelling species, found mainly in intertidal coralline areas (Ref. 128042). Occurs in shallow subtidal areas on soft sediment substrates (Ref. 96968).
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.
