Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 15; Espinas anales: 0; Radios blandos anales: 16 - 17. Teeth on maxilla 7. POSTORB single. AC greatly arched behind the anal fin base. Stem of barbel black; the distal end forming a small, spherical white bulb lacking filaments (Ref. 559). Body moderately slender and elongate. Serial photophores not broken in small groups. Black in color (Ref. 37039).
Quite common in deep oceanic waters, usually living deeper than 500 m during the day. Smaller individuals migrate to near-surface or even surface waters at night. Feeds on midwater fishes and crustaceans (Ref. 2802).
