Minimum depth assumed from its ecology. Inhabits intertidal and shallow subtidal zones, on reefs and sandy areas. Found on crevices, boulders and empty gastropod and bivalve shells. Selectively feeds on grapsid crabs and small bivalves. Known to extract living hermit crabs on gastropod shells via drilling. Major source of food for juvenile shark in Argentinean waters (Ref. 96968).

Livscykel och parningsbeteende Könsmognad | Reproduktion | Lek | Ägg | Fekunditet | Larver

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.
