Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino batipelagico; oceanodromo (Ref. 51243); distribuzione batimetrica 50 - 2500 m (Ref. 26165), usually 500 - 600 m (Ref. 4775). Deep-water; 50°N - 50°S, 180°W - 180°E
Circumglobal in tropical and temperate waters, but with a distinct equatorial gap in the Pacific (Ref. 9835). Western Atlantic: Canada to Brazil. Eastern Atlantic: Morocco to Mauritania and from Liberia to Namibia (absent in Mauritanian Upwelling Region). Indian and Pacific: confined to southern equatorial water masses, extending to 50°N and 50°S in western boundary currents. South China Sea (Ref.74511).

High-oceanic, epipelagic to mesopelagic, found in 375-750 m during the day and near the surface to 125 m at night (Ref. 4066, 58302). Adults feed on zooplankton (Ref. 9835). Caudal glands develop in both sexes from about 1.9 cm (Ref. 4775). Oviparous, with planktonic eggs and larvae (Ref. 31442).
