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 40 - 475 m (Ref. 4479). Deep-water; 42°N - 27°S
Eastern Atlantic: Mauritanian Upwelling region and Gulf of Guinea south to 23°S. Western Atlantic: USA (Gulf Stream) to Gulf of Mexico and the Caribbean Sea. Northwest Atlantic: Canada (Ref. 5951). Reported off the Guianas (Ref. 13608).
Length at first maturity / Size / Weight / سن
Maturity: Lm 3.8, range 4 - 4 cm
Max length : 7.0 cm SL جنس نر / بدون خواص جنسي; (Ref. 4479)
خارهاي باله پشتي (کل) : 0; شعاع نرم باله پشتي (کل) : 13 - 15; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 13 - 15. Small, stout-bodied myctophid with well developed eyes, swim bladder and associated gas gland (Ref. 9185).
Pseudoceanic, found over continental shelves and slopes (Ref. 4066). Occurs between 325-475 m during the day; between 40-250 m at night (maximum abundance in 100 m depth). Mesopelagic (Ref. 5951). In the Cariaco Trench, day distribution is at 250 m and at night at 50 m due to anoxic conditions below 400 m and free hydrogen sulphide below 375 m. Fecundity is about 1,000 eggs per female (Ref. 9504).
