(See ETYFish).

Probably oceanic (Ref. 5578). The holotype was caught off a beach, but a second specimen was taken in the Atlantic at night between the surface and 502 m (Ref. 247). Food unknown but may subsist on pelagic fish and invertebrates (Ref. 247). Probably ovoviviparous with very few young (Ref. 247).
