Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 17 - 21; Anal spines: 0; Anal soft rays: 18 - 24; Vertebrae: 47 - 51. This species possess the following characters: in male, postorbital photophore (PO) 5.8-11.9% upper jaw length (UJL), 1.5-3.1% SL; female PO 2.8-8.1% UJL, 0.8-11.9% SL; IP photophores 3-5 in 3-5 clusters (Ref. 78501).
Body shape (shape guide): elongated.

Biology     Glossary (e.g. epibenthic)

Meso- and bathypelagic (Ref. 58302). It has been suggested that this species does not undergo substantial diel vertical migration and remains below 500 m (Ref. 78501). Feeds on crustaceans and fishes (Ref. 58426).

Estimates based on models

Preferred temperature (Ref. 123201): 2.3 - 6, mean 3.6 °C (based on 3340 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00407 (0.00157 - 0.01056), b=3.10 (2.88 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.58 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100). 🛈
