पारिस्थितिकी
समुद्री बैथीपिलाजिक; गहराई सीमा 500 - 7625 m (Ref. 58426), usually 1200 - 1400 m (Ref. 559). Deep-water; 67°N - 56°N, 180°W - 180°E
Circumglobal: In tropical to temperate waters. Eastern Pacific: ranges from northern California to Peru (Ref. 35600).
आकार / वज़न / Age
Maturity: Lm ? range ? - ? cm
Max length : 100.0 cm TL पुल्लिंग / अलिंग; (Ref. 27000); common length : 55.0 cm NG पुल्लिंग / अलिंग; (Ref. 5755)
पृष्ठीय रीढ़ (सम्पूर्ण): 0; गुदा कांटा 0. Mouth greatly enlarged by a backward extension of jaws, gape comprising half or more of preanal length; buccal cavity greatly distensible. Tail attenuated and ending in an expanded, luminous caudal organ. Caudal fin absent; scales absent; lateral line without pores, instead with groups of elevated tubules.
Meso- to abyssopelagic (Ref. 58302) and bathypelagic (Ref. 58426). Adults feed mainly on crustaceans, but also take fishes, cephalopods, and other invertebrates (Ref. 2850, 11041). Oviparous, planktonic eggs hatch into planktonic leptocephalus larvae (Ref. 6719, 35600). Degenerative changes in males and females suggest semelparity (Ref. 35600).

Oviparous (Ref. 35600). Degenerative changes in males and females suggest semelparity (Ref. 35600). Egg cells within each of the gonads have the same developmental stage (monocyclic ovaries) suggesting only one spawning during its lifetime or periodic spawning (Ref. 36055).
