Western Atlantic: 20°N to Brazil including the Gulf of Mexico, with expatriates in the slope water region. Eastern Atlantic: Mauritania to South Africa (Agulhas water pockets). Northwest Atlantic: Canada (Ref. 5951). Indo-Pacific: north and south equatorial currents and equatorial countercurrents, and in the east Australian and Agulhas currents. Also in the Eastern Central Pacific (Ref. 9325). Larvae found in Taiwan Strait (Ref. 43570). South China Sea and East China Sea (Ref.74511).
Neustonic to mesopelagic (Ref. 58302). High-oceanic, nyctoepipelagic at the surface and down to 125 m. Found between 425-750 m during the day. Sexually mature from about 65 mm (Ref. 4479). Proximate analysis (excluding head) reveals that lipid content is 2.0 % in fresh body weight and wax ester is 17.2 % in total lipids (Ref. 9193).
