Frequently caught in bottom trawls together with Eledone gaucha Haimovici, 1988 (Ref. 104514). Benthic (Ref. 104514). Coexists with Eledone gaucha along the continental shelf and slope. Inhabits soft bottoms, on both sandy and muddy bottoms. Feeds mainly on crustaceans such as crabs and stomatopods (Ref. 104173).

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). Eggs are attached on a hard substrate. Females die after releasing the hatchlings (Ref. 104514).
