Resilience: Distribution:
Distribution : Circumglobal: Western Pacific (Ref. 6885, 7300); Eastern Pacific: from the Aleutian Islands to Chile, also (Ref. 2850); Western Atlantic: Gulf of Maine to the Gulf of Mexico and the Caribbean Sea, also (Ref. 7251); Eastern Atlantic (Ref. 4059).

Dorsal fin very high, about three rays beginning with third or fourth much exerted; adipose moderate in size, over posterior part of anal insertion (Ref. 6885). Generally pale, iridescent, darker dorsally; lateral adipose keel dark; all fins dark brown or black; peritoneum black (Ref. 6885). Branchiostegal rays: 7-8 (Ref. 36025).
Biology : Mainly inhabit tropical and subtropical waters; however, during the feeding period adults may migrate to the subarctic reaching as far north as Greenland, Iceland and the Bering Sea (Ref. 51887). Epipelagic- and mesopelagic, from near the surface to below 1,000 m, sometimes approaching inshore waters (Ref. 6011). Bathypelagic (Ref. 58302). Mainly nocturnal. Feed on fishes, cephalopods, tunicates, and crustaceans (Ref. 6011). Preyed upon by opah, sharks, albacore, yellowfin tuna, and fur seals (Ref. 6885). Oviparous, with planktonic larvae (Ref. 36025).
