Length at first maturity / Size / Weight / Age

Maturity: Lm ?  range ? - ? cm Max length : 70.0 cm TL male/unsexed; (Ref. 96968); common length : 30.0 cm TL male/unsexed; (Ref. 83447)

Biology     Glossary (e.g. epibenthic)

The species is light to dark gray in color, but when in danger or stimulated, it turns to dark red (Ref. 83447). Its mantle length is 8 cm (Ref. 96968). Maximum depth from Ref. 106826. Benthic, littoral species to a depth of 200 (Ref. 106826). Found on mud and mud sand (Ref 112117). Feeds on crustaceans. Common bait are small live crabs (Ref. 112117).

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.
