Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 14 - 17; Anal spines: 0; Anal soft rays: 28 - 31. Black in color with dusky pigmentation on median fins; pectoral and pelvic fins are colorless (Ref. 3988).

Mesopelagic, adults found in 500-700 m depth (Ref. 4470). Living on or near the bottom, probably moves in schools (Ref. 37473).

Estimates based on models

Preferred temperature (Ref. 123201): 6.3 - 9.3, mean 7.6 °C (based on 44 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00316 (0.00131 - 0.00766), b=3.17 (2.95 - 3.39), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.50 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).

Price category (Ref. 80766): Unknown.
