Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 76 - 84; Anal spines: 0; Anal soft rays: 56 - 65; Vertebrae: 41 - 43. Pronounced dark coloration on most of blind-side head (supracranial area, anterior half of cranial area and cheek, antero-ventral part of opercular area), basal part of dorsal and anal fin rays and pelvic fin; in specimens longer than 19 cm, dark coloration replaced by gray, diffuse color, paler on larger specimens; gill opening on the eyed side forming short slit equal or smaller than nostril diameter; and 92-114 series of scales (Ref. 49504).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00417 (0.00168 - 0.01037), b=3.10 (2.88 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.6 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 (19 of 100).
