Short description Morphology | Morphometrics

Dorsal spines (total): 14 - 16; Dorsal soft rays (total): 6-8; Anal spines: 3; Anal soft rays: 7 - 8. Distinguished from congeners by the combination of the following characters: seven to eight horizontal rows of mostly triangular black spots along sides; rounded caudal fin, horizontally split spot on caudal base in males; straight, narrow cheek stripe, and body more high-backed compared to similar species.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02239 (0.00860 - 0.05828), b=3.03 (2.81 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.4 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months ().

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