Maturity: Lm ?  range ? - ? cm Max length : 10.0 cm ML male/unsexed; (Ref. 275)
Mantle cylindrical, short, its width about 25% of the mantle length. Fins rhomboidal, length about 60% of mantle length. Tentacular clubs expanded, suckers 56-60, quadriserial, 8 proximal suckers greatly enlarged with smooth rings, teeth absent; medial and distal rings with 7 to 10 very low, broad, plate-like or semilunar teeth. Arm suckers biserial; sucker rings on arm III with 3 to 6 truncate teeth. Left ventral arm hectocotylized along distal 2/3 with about 75 suckerless papillae. (Refs. 275, 128027).
A small-sized, coastal species found ca. 50 m depth (Refs. 275, 128024) (Ref. 275).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | 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.
