簡単な記述
形態学 | 形態計測学
背面の脊椎 (合計): 0; 背鰭 (合計): 300; 肛門の骨 0. Dorsal fin with up to 350 rays; caudal much reduced, linear; anal fin rays 265-270 or more; pectorals small (Ref. 6885). Uniform dusky brown, except jaws, pectoral fins, and lower abdomen which are paler (Ref. 6885). Strong sexual dimorphism (Ref. 3247).
Meso- and bathypelagic (Ref. 58302). Feed on crustaceans (Ref. 3247). Oviparous, with planktonic leptocephali (Ref. 32364). Degenerative changes in males and females suggest semelparity (Ref. 32364). Minimum depth from Ref. 58018.
