Maximum depth from Ref. 105659. Mesopelagic to bathypelagic as adults (Ref. 97142). Found on the upper slope at depths of 600-800 m (Ref. 1970). Frequently found in stomach contents of several species of bony fishes, sharks, mammals and seabirds; confirming that the species is common in its distributional areas, even though seldom captured by commercial fishing gear (e.g. trawls). Biology is poorly known; paralarvae and juveniles are epipelagic to mesopelagic and widespread in the water column. Possibly gregarious as numerous specimens are commonly captured together in deep net tows, a characteristic generally uncommon in deep sea squids (Ref. 97142).

Life cycle and mating behavior परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | 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.
