Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 12 - 15; Anal spines: 0; Anal soft rays: 17 - 20; Vertebrae: 31 - 33. Body dark-brown or black; margin of scale pockets especially dark; area immediately anterior to anal origin densely pigmented and not transparent; peritoneum black, ending above area between 3rd and 4th VAV, usually invisible from the outside (Ref. 559). Gill lamellae free and reduced (Ref. 559).

Meso- to bathypelagic (Ref. 58302). Inhabits deep water and is only captured with special equipment. Lipid content is 4.0 % in fresh body weight and wax ester is 58.4 % in total lipid (Ref. 9193). Protandrous hermaphrodite, oviparous with planktonic eggs and larvae (Ref. 35800).

Estimates based on models

Preferred temperature (Ref. 123201): 1.7 - 7.3, mean 2.4 °C (based on 579 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): 3.1 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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