Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 13 - 15; Spine anali: 0; Raggi anali molli: 17 - 20. Brown to brown-black in color; dense stellate pigment over head, body and fins (Ref. 3991).

An oceanic, deep mesopelagic to bathypelagic species (Ref. 4769). Precise depth range dependent upon developmental stage, latitude, season (Ref. 4769). Doest not exhibit diel vertical migrations (Ref. 4769). A non-seasonal breeder with no recognizable age-cohorts (Ref. 82363). Feeds mainly on copepods (Ref. 4769).

Estimates based on models

Preferred temperature (Ref. 115969): 1.8 - 8.2, mean 3.2 (based on 7820 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00171 - 0.00885), b=2.99 (2.79 - 3.19), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.13 se; based on food items.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Assuming tm>1; Fec=2,000-10,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
