Occur in midwater, usually below 400 m and occasionally in shallow water in the northern part of its range. Feed on crustaceans while swimming with its mouth open (Ref. 5377). Mesopelagic (Ref. 58302) and bathypelagic (Ref. 58426). Oviparous, with planktonic leptocephali (Ref. 32364). Degenerative changes in males and females suggest semelparity (Ref. 32364).
