Remarks	Circumglobal in tropical and subtropical open oceanic waters; known from 43°N to 35°S, generally prescribed by the north and south subtropical convergences. Paralarvae and juveniles are epipelagic to upper mesopelagic, upper 400 meters, while adults descend to mesopelagic and bathypelagic zones, perhaps up to 2,000 meters deep (Ref. 97142).
