Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 10; Dorsal soft rays (total): 13; Anal spines: 3; Anal soft rays: 14. This species is distinguished by the following set of characters: body depth at pectoral fin base 2.5-2.9 in SL, at mid-trunk 2.4-2.9 SL; dorsal-fin origin is above the bases of the pectoral fins; preopercle with a slightly elongate and blunt spine reaching or beyond the posterior margin of the interopercle; dorsal-fin base, 1.7-1.8 in SL; anal-fin base 2.5-2.8 in SL, relatively short; eye is relatively large, its diameter 2.0-2.6 in HL; interorbital space is narrow, its width 3.3-4.1 in HL; head length 1.1-1.3 in body depth; caudal-peduncle length 2.5-3.2 in body depth; pored lateral-line scales 59-78; lateral scale rows 81-96; transversal scales rows 10-12 + 49-57 = 60-69 (Ref. 115564).
Cross section: compressed.
Often photographed or collected from shallow water not deeper than 100 meters (Ref. 115564).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02239 (0.00954 - 0.05253), b=2.93 (2.72 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (19 of 100).
