بوم شناسي
دريايي ناحیه ای از منطقه اقیانوسی با عمق بین 1000 تا 4000 متر. موجوداتی که در آبهای آزاد بین اعماق 1000 تا 4000 متر زندگی و تغذیه می کنند; تغييرات عمق 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).
Size / Weight / سن
Maturity: Lm ? range ? - ? cm
Max length : 100.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 27000); common length : 55.0 cm NG جنس نر / بدون خواص جنسي; (Ref. 5755)
خارهاي باله پشتي (کل) : 0; خارهاي باله مخرجي: 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).
Life cycle and mating behavior
بلوغ | تولید مثل | تخم ریزی | تخم ها | Fecundity | توزاد ( لارو)
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).
