Environment: milieu / climate zone / depth range / distribution range
Écologie
marin bathypélagique; profondeur 1 - 3000 m (Ref. 74511). Deep-water
Eastern Atlantic: Madeira (Ref. 2802) to off South Africa (Ref. 4465). Western Atlantic: 25°N-5°N. Indo-Pacific: eastern Africa, Gulf of Aden and Bay of Bengal to the vicinity of the Hawaiian and Japanese islands, the Philippines and northwestern Australia.
