Environment: milieu / climate zone / depth range / distribution range Ecology

Benthopelagic; depth range 200 - 3000 m (Ref. 1695). Tropical; 52°N - 35°S, 85°W - 46°E (Ref. 106956)

Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions

Atlantic, Mediterranean, Western Indian Ocean and the Pacific.

Length at first maturity / Size / Weight / Age

Maturity: L_m ? range ? - ? cm Max length : 2.5 cm ML male/unsexed; (Ref. 1695)

Mesopelagic or benthopelagic, but also found on the bottom at depth range to 1588 m, paralarvae found in mesopelagic and bathypelagic zones, far from coasts, with bottom depth ranging between 1,500 and 3,000 m. Adults live in groups in lower epipelagic and mesopelagic zones, common at depths between 200 and 300 m. Often found in areas inhabited by populations of red shrimps. Represents a sizeable component of the diet of several top predators, including dolphins, sharks, swordfish and tunas. Caught by pelagic nets and shrimp trawlers but of no commercial interest due to the low quantities available to fisheries (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.
