Biology     Glossary (e.g. epibenthic)

Pseudoceanic and mesopelagic, occurring singly or in small schools (Ref. 5759), primarily at 200-1000 (Ref. 58302). Feed mainly on fishes and shrimps (Ref. 5759). Spawn in continental slopes and in oceanic banks from northern through tropical to southern temperate waters. Oviparous, with planktonic larvae (Ref. 35950).

Estimates based on models

Preferred temperature (Ref. 123201): 0.8 - 10.8, mean 4.1 °C (based on 2120 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00224 (0.00090 - 0.00555), b=3.14 (2.92 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.0 se; based on diet studies.
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
Nutrients (Ref. 124155):  Calcium = 49.9 [16.8, 160.1] mg/100g; Iron = 0.548 [0.182, 1.750] mg/100g; Protein = 15.6 [12.5, 18.2] %; Omega3 = 0.105 [0.029, 0.325] g/100g; Selenium = 27.5 [7.9, 78.4] μg/100g; VitaminA = 14.2 [1.6, 119.9] μg/100g; Zinc = 0.615 [0.321, 1.262] mg/100g (wet weight);
