Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 7 - 9; Anal spines: 0; Anal soft rays: 23 - 27; Vertebrae: 50 - 54. Adipose fin far back on caudal peduncle, relatively large and long; pectorals rather small (Ref. 6885). Color black to dark brown (Ref. 6885).

Occurs at a minimum depth of 550 m upon reaching about 5 cm length (Ref. 54657; 82347). Oviparous, with planktonic eggs and larvae (Ref. 35604). Generally mesopelagic and bathypelagic and not ascending to epipelagic depth range (Ref. 96339).

Estimates based on models

Preferred temperature (Ref. 115969): 1.6 - 2.5, mean 1.8 (based on 1197 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00428 - 0.01408), b=3.04 (2.87 - 3.21), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.1 se; based on diet studies.

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (23 of 100).
