Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 12; Anal soft rays: 17; Vertebrae: 32. First and second supra-abdominal photophores at the same level, with the third elevated. Darkly pigmented area of predorsal do not reach the median line of the body and is separated from the subdorsal dark area; the anterior part of the darkly pigmented predorsal is concave ventrally. Vomerine teeth present only on lateral edge (Ref. 37378).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02291 (0.01031 - 0.05092), b=2.94 (2.74 - 3.14), 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).
