Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 11; Anal spines: 1; Anal soft rays: 8; Vertebrae: 25 - 26. This species is distinguished by the following: spinulated (without gap) posterior and lower edges of praeoperculum; insertion of ventral fins in front of the vertical of posterior eye edge; soft rays in dorsal 11 and in anal fin 8; rakers at the first gill arch 29-33; vertebrae 25-26; pyloric caeca 9-11 (Ref. 83717).

Collected with non-closing fishing gear that precise depths of its occurrence is undetermined. Depths of catches are 200-0 minimum and 5300-0 maximum (Ref. 83717).

Estimates based on models

Preferred temperature (Ref. 123201): 1.8 - 3.1, mean 2.2 °C (based on 2546 cells).

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

Bayesian length-weight: a=0.01072 (0.00442 - 0.02595), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

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