Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 11 - 13; Spine anali: 0; Raggi anali molli: 12 - 14. Uniform brown in color, mouth and belly darker (Ref. 6604). Branchiostegal rays: 8 (Ref. 36062). Lacks luminous organs and a gas bladder (Ref. 36062).

Biologia     Glossario (es. epibenthic)

High-oceanic and bathypelagic (Ref. 6604). Adults usually found below about 1,000 m, but juveniles found between 500-800 m. No evidence of vertical migration (Ref. 6604). Feed mainly on small crustaceans. Sexually mature from about 15.2 cm (Ref. 4525). Oviparous, with planktonic larvae (Ref. 36062).

Estimates based on models

Preferred temperature (Ref. 123201): 4.2 - 7.7, mean 5.7 °C (based on 645 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7656   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00363 - 0.02397), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.30 se; based on food items.
Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
