Maturity: Lm ?  range ? - ? cm Max length : 2.5 cm ML mâle / non sexé; (Ref. 1695); 2.8 cm ML (female)
Found along the outer shelf between 26 and 498 m depth. Mating takes place when the male grasps the female's 'neck' region, and spermatophores are placed in the female's bursa copulatrix. Males have been observed to guard females during courtship. Contributes (although in low numbers) to the local trawl fishery as one of the most frequently captured Mediterranean species of this genus (Ref. 1695).
Life cycle and mating behavior
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
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.
