Γεννητική Ωρίμανση: Lm 29.7 range ? - ? cm Max length : 400 cm TL αρσενικό/απροσδιόριστο; (Αναφ. 275); common length : 80.0 cm TL αρσενικό/απροσδιόριστο; (Αναφ. 275); μεγ. δημοσιευμένο βάρος: 3.0 kg (Αναφ. 275)
Common total length: 50 to 80 cm. Caught by jigs (Ref. 275). Maximum total length is 4 m. Common length is about 50 to 80cm (Ref. 3722). Inhabits offshore areas of continental shelves from surface to depths of at least 1200 m. Found over the shelves and near shores during feeding. Adults undergo diel vertical migrations with a night lift to the 0-200 m water layer, going down at daytime to depths of 800-1,000 m and deeper (Ref. 2130). Upper temperature limits range from 30 to 32°C in equatorial areas, while deeper water temperature limits are not less than 4 to 4.5°C. Active predator, feeds actively at dusk and dawn. Commonly feeds on copepods, hyperiid amphipods, euphausiids, pelagic shrimps and red crabs (Pleuroncodes planipes), heteropod mollusks, squid, octopods and various fish. Exhibits cannibalism, but only on juvenile squids (Ref. 1982).
Life cycle and mating behavior Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | 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.
