Has a color pattern of a dark brown to purple longitudinal stripe along the dorsal faces of at least arms I to III. Dark purple angular reticulations are also present on the lateral arm crown, with contrastring pink to white suckers. Papillae are dense, some of which coalesce into longitudinal bars on the lateral mantle.
Its mantle length is 10 cm (Ref. 96968). Found from shallow subtidal to at least 190 meters. Known from coastal muddy waters on mud and substrates. Feeds on crustaceans like crabs Calappa sp., and bivalves. It makes dens in clamshells, coconut shells, bottles and other man-made discarded objects in sand and mud. It will carry one mollusk shell or half a coconut shell while searching for another shell in which to enclose itself (Ref. 96968).
Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | 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.
