It's mantle length is 8 cm (Ref. 96968). Found in intertidal to shallow subtidal areas. Forages on exposed intertidal coral reef flats and sand areas during night low tides; occupies lairs within coral bedrock and under living coral, blocking the entrance during the day with pieces of dead coral. Feeds mainly on small crabs and other crustaceans. Larger individuals readily attack smaller conspecifics. The eggs are small and hatchlings planktonic (Ref. 96968).
Life cycle and mating behavior
بلوغ | تولید مثل | تخم ریزی | 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.
