Lateral line an open groove, bridged by scales at intervals. Swim bladder present. Juveniles: long cephalic and preopercular spine; big eye; teeth on jaws small, multiserial on premaxilaries; no teeth on palatine and vomer; gill rakers long and slender.

Bathypelagic (Ref. 58426). Adults occur mainly between 500 and 2,000 m, but ranging from near the surface (young) to 5,000 m. Form schools, swim in small groups or solitary. Carnivorous (Ref. 27155), feeding on crustaceans when young and on fish mainly when adults (Ref. 4737). Serve as food for pelagic fishes such as tuna, albacore, and marlin (Ref. 5951). Oviparous, with planktonic larvae (Ref. 36624).
