Description synthétique Clés d'identification | Morphologie | Morphométrie

Rayons mous dorsaux (Total) : 16 - 18; Rayons mous anaux: 19 - 25; Vertèbres: 60 - 63. This species of the subgenus Trachinostomias is distinguished by the following characters: vertebrae 60-63 (as an exception, can be reduced to 58); photophores of series IV, 41-45; jaws with uniformly sized teeth; pectoral fin, usually 1 ray P (as an exception, 0 or 2); body with spots of white luminous tissue; mental barbel with a small bulb or even without it, but always with the developed appendages (Ref. 125184).

Mesopelagic species (Ref. 559).

Estimates based on models

Preferred temperature (Ref. 123201): 2 - 4.6, mean 3 °C (based on 2643 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00117 - 0.00783), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.0 ±0.70 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (38 of 100).
