Μέγεθος / Βάρος / Age
Maturity: Lm ? range ? - ? cm
Max length : 102 cm TL αρσενικό/απροσδιόριστο; (Ref. 1371)
Ραχιαίες άκανθες (συνολικά): 2; Μαλακές ραχιαίες ακτίνες (συνολικά): 123-124; Εδρικές άκανθες 0; Μαλακές εδρικές ακτίνες: 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).
