Circumglobal in tropical and subtropical waters (Ref. 41299). Eastern Atlantic: Mauritania south to Angola. Also across the Atlantic between 0 and 20°N, extending to 35°N and 39°S in the western part (USA to Argentina). South China Sea, East China Sea and waters near to Taiwan (Ref.74511).
Some individuals may migrate to the surface at night (Ref. 27000). Minimum depth reported taken from Ref. 27000. Feed mainly on myctophids (Ref. 47377).
