Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 11 - 15; Spine anali: 0; Raggi anali molli: 27 - 32; Vertebre: 39 - 41. Black in color, slightly silvery laterally; fins dusky and with small black spots; distal portion of pectorals and pelvic fins colorless (Ref. 3991). Dorsal adipose fin present. Branchiostegal rays: 12-13 (Ref. 35800).

Meso- to bathypelagic (Ref. 58302). Occur between 100-200 m and 500-800 m at night and 25-600 m and 1,250-1,500 m during the day (Ref. 4463). Feed on crustaceans and small fishes (Ref. 4769). Photophores develop in fishes over 6-22 mm SL (Ref. 4769). Protandric hermaphrodite, oviparous with planktonic eggs and larvae (Ref. 35800). Minimum depth from Ref. 4463.

Estimates based on models

Preferred temperature (Ref. 123201): 2.9 - 19.2, mean 6.9 °C (based on 5921 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00288 (0.00164 - 0.00507), b=3.03 (2.87 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.40 se; based on food items.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (18 of 100).
