биология     глоссарий (например 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. 115969): 4.2 - 7.7, mean 5.7 (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.
устойчивость к внешним воздействиям (Ref. 120179):  средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
