Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 8 - 9; Épines anales: 0; Rayons mous anaux: 12 - 14; Vertèbres: 38 - 41. Scales deciduous; swim bladder well developed, gas-filled, euphysoclistous; branchiostegal rays 10, 3 on epihyal; post-abdominal spines (iliac) short, equal in length; abdominal keels shallow (Ref. 4739).
Body shape (shape guide): short and / or deep.
An oceanic and mesopelagic species (Ref. 4739, 58302), mainly at 300-650 m (Ref. 4054), 170-500 m at night and 350-600 m during day (Ref. 58302), commonly 1-600m (Ref. 035838). May make short diel migrations (Ref. 4739). Smaller individuals feed on copepods and ostracods; larger ones feed on euphausiids, salps and chaetognaths (Ref. 4739). Adult complement of photophores acquired at about 14 mm SL (Ref. 4739). Oviparous, with planktonic eggs and larvae (Ref. 35838).
