Short description Morphology | Morphometrics

Dorsal soft rays (total): 10; Anal soft rays: 21 - 23; Vertebrae: 36 - 38. A conspicuous dark blotch present at the humeral region. Scales rows between dorsal-fin origin and anal-fin origin 7-8.

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00548 - 0.02519), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
