Climate / Range

Southeast Pacific: Peru and Chile. Subtropical to temperate.
Depth range is based on occurrence in Chile (Ref. 105062); to be replaced with a better reference. Benthic (Ref. 106857). Found in shallow waters (Ref. 105062) in rocky intertidal area (Ref. 106857). Opportunistic predator. Feeds on bony fishes, molluscs, crustaceans, echinoderms and polychaetes. Occasionally exhibits cannibalism (Ref. 105056). Reported to perform hole-drilling on its prey (Ref 105064). 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 (Ref. 833).
