Short description Morphology | Morphometrics

Dorsal soft rays (total): 7; Anal soft rays: 6. Dorsal series of lateral scutes on both sides not meeting along the middorsal line between the end of dorsal-fin base and the adipose fin; both tooth lobes approximately equal size; orbital diameter 12.0-14.7% HL (Ref. 42856).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00550 (0.00206 - 0.01463), b=3.12 (2.89 - 3.35), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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).
