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 282 - 5180 m (Ref. 50610). Deep-water; 65°N - 61°S, 180°W - 180°E (Ref. 1371)

Size / Weight / سن
Maturity: Lm ? range ? - ? cm
Max length : 102 cm TL جنس نر / بدون خواص جنسي; (Ref. 1371)
خارهاي باله پشتي (کل) : 2; شعاع نرم باله پشتي (کل) : 123 - 124; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 115. The head is large; the eyes also large. The snout is elongated, somewhat conical; the mouth is small and inferior. The body tapers from behind the first dorsal fin. The light organ extends past midway between the anal origin and the ventral insertion. Color is uniformly brownish, except for the abdomen which is bluish.
A deep-slope upper continental rise species, common in deep waters of most oceans (Ref. 1371). Bathypelagic (Ref. 58426). Feeds on a variety of benthic invertebrates (especially crustaceans and holothuroids) when young, switching to primarily mesopelagic and bathypelagic fish, and sea urchins and cephalopods as adults (Ref. 1371). Sex ratio was 2.6:1 male to female (n = 449) in the Rockall Tough, N.E. Atlantic (Ref. 40742).
