Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 0; Mjukstrålar i ryggfenan (totalt): 14-16; Taggstrålar i analfenan 0; Mjukstrålar i analfenan: 18 - 19; Ryggkotor: 36 - 38. 15-16 AO photophores; 7-8 tooth patches on lower limb of second gill arch; 35-38 lateral line organs (Ref. 36121). Pectoral fins well developed with rather robust, stout rays (Ref. 36121). Nearly black to metallic blue dorsally, lighter on sides, black in mouth and gill cavity; fins dusky, marked with fine wavy lines (Ref. 6885).
Epipelagic to mesopelagic (Ref. 31442). Adults feed on Sagitta, young fishes, copepods, and euphausiids (Ref. 6885). Oviparous, with planktonic eggs and larvae (Ref. 31442). Lipid content is 14.2 % in fresh body weight and wax ester is 58% in total lipids (Ref. 9197).
