Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7 - 8; Dorsal soft rays (total): 12; Anal soft rays: 12; Vertebrae: 26 - 27. This species is distinguished by the following characters: no antrorse AIO spine, long (20-28%SL); pectoral fin reaches just beyond anal fin origin (32-36% SL); eye large (11-15% SL); pterygiophores exposed along base of D1 (large plates including one in advance of first D1 spine) and D2 fins with small spines at ray bases that are directed anteriorly (Ref. 95016).

Estimates based on models

Preferred temperature (Ref. 123201): 2.9 - 5.1, mean 3.9 °C (based on 393 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00513 - 0.03091), b=3.01 (2.80 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (14 of 100).
Price category (Ref. 80766):   Very high.
