Max length : 27.0 cm TL male/unsexed; (Ref. 9710)
soft rays: 8 - 10. Body with about equal stripes of brownish red and silvery white; spinous dorsal mostly white, membrane tips yellow, basal part of fin red except base of first two membranes which are whitish (Ref. 4201). Five oblique scale rows on cheek; body depth 2.4-2.65 in SL; head length (HL) 2.55-2.9 in SL; short and blunt snout, its length 4.15-4.6 in HL; interorbital width 4.5-5.2 in HL; mouth terminal, maxilla usually extending posterior to center of eye, upper jaw length 2.2-2.45 in HL; premaxillary groove nearly or just reaching a vertical at front edge of orbit; anterior end of nasal bone with a blunt spine; surface or medial edge of nasal bone spineless; nasal fossa without spinules; upper edge of 1st suborbital bones with a row of recumbent spinules, the 1st (slightly posterior to a vertical at front edge of orbit) is the largest and most lateral; preopercular spine usually slightly more than 1/2 orbit diameter, 4.0-5.7 in HL; 3rd-5th dorsal spines longest, 1.75-2.15 in HL; 3rd anal spine 1.3-1.55 in HL (Ref. 27370).

Estimates based on models
Preferred temperature (Ref. 115969
): 25.4 - 28.9, mean 27.2 °C (based on 435 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00759 - 0.03307), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.6 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.).
Vulnerability (Ref. 59153
): Low vulnerability (21 of 100) .
