Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 8 - 12; Épines anales: 0; Rayons mous anaux: 22 - 28. Body black in color, often iridescent (Ref. 3982). Teeth in jaws uniserial, very short, spine-like, about equally spaced (Ref. 559). Snout shorter than eye (Ref 559). Anal fin with many rays; its base long, more than twice that of dorsal (Ref. 559). Gill rakers much attenuated, numerous, close together (Ref. 559).
An oceanic and mesopelagic species usually found deeper than 500 m during the day (Ref. 2802). Feeds on midwater fishes and crustaceans (Ref. 2802). Also Ref. 58302.
