पिलाजिक; गहराई सीमा 250 - 4000 m (संदर्भ 1978), usually 1500 - 2500 m (संदर्भ 1978). Polar; 3°C - 3°C (संदर्भ 1987)
Northern Atlantic. Subtropical to polar.
Length at first maturity / आकार / Weight / Age
परिपक्व अवधि: Lm ?  range ? - ? cm Max length : 11.4 cm ML पुल्लिंग / अलिंग; (संदर्भ 1978); 9 cm ML (female)
Lower depth from Ref. 1987. Known lengths are: total length, 50 cm; maximum unsexed mantle length, see value above (Ref. 96968), and male mantle length, 7.8 cm (Ref. 1978). Typically captured within about 100 m off the bottom. Bioluminescence has been reported from the sucker bases of this octopod (Ref. 96968). This is a benthopelagic species (Ref. 1978).
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.
