Environment

Bathydemersal; marine; depth range 110 - 1000 m (Ref. 58302), usually 200 - 400 m (Ref. 35388)

Climate / Range

Deep-water; 70°N - 48°S, 180°W - 180°E

Worldwide in temperate and tropical latitudes, except the eastern Pacific. Eastern Atlantic: Greenland, Iceland, and Norway to Western Sahara and South Africa, including western Mediterranean. Western Atlantic: south to Brazil. Indo-Pacific: East Africa (including the Madascar Ridge and Saya de Malha Bank, Ref. 33390) to Japan, Australia, and New Zealand (Ref. 5755). The limited number of records in the western Pacific is doubtless the result of limited fishing effort below 200 m (Ref. 9833).
