serial photophores in lateral row (OA) 32–35, of which 18–21 behind pelvic fin insertion (VAL); 51–55 photophores in ventral row to tail (IC); ventral row straight between pectoral fin bases. Barbel a tiny rudiment. Dorsal-fin rays 17–20. Color of head and body silvery on black background; in larger specimens a narrow pale patch on most of anterior part of gill cover, coalescing patches between lateral and ventral photophore rows, and dots often present on sides of head and body.

Fairly common in deep oceanic waters, usually living deeper than 500 m during the day. Smaller individuals migrate to the near-surface or even surface waters at night. Feeds on midwater fishes and crustaceans.
