Maturity: L_m ? range ? - ? cm Max length : 5.1 cm ML male/unsexed; (Ref. 1695); 8.3 cm ML (female)

Most bathyal among the members of the family. Demersal. Prefers deep muddy bottoms characterized by Isidella elongata populations, often overlapping with Rossia macrosoma in the upper level of its distributional range and frequently associated with Sepietta oweniana and Rondeletiola minor. In the western Mediterranean, it is the most common cephalopod captured between 1000 and 2000 m, along with Bathypolypus sponsalis but is most abundant between 400 and 600 to 700 m in both eastern and western parts of this sea. Mature individuals found throughout the year suggest an extended spawning season. Its large eggs (8-10 mm diameter and covered by a hard violet-coloured coating), are attached to hard substrates at various depths. Lifespan approximated between 12 and 24 months. Usually taken as trawl fishery bycatch; of minor commercial importance. Sold fresh and frozen in fish markets with other bobtail squids (Ref. 1695).

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.
