Short description Morphology | Morphometrics

Dorsal spines (total): 11 - 77; Dorsal soft rays (total): 12-13; Anal spines: 4; Anal soft rays: 8 - 9. Body with 9 red stripes alternating with 9 narrower white stripes that pass along the middle of the longitudinal scale rows; head red with a white bar along the posterior margin of preopercle. Five oblique scale rows on cheek; body depth 2.45-2.75 in SL; head length (HL) 2.5-2.7 in SL; snout length 3.6-4.0 in HL; large eyes, orbit diameter 2.6-3.1; least interorbital width 4.5-5.1 in HL; maxilla extending from a vertical at front edge of the pupil to slightly beyond the center of the eye, upper jaw length 2.45-2.8 in HL; premaxillary groove usually not reaching a vertical at front edge of the orbit; rounded anterior end of nasal bone; moderately large nasal fossa, often spineless (1 specimen with 1 spinule on anterior edge on one side, another with 2 projecting outward); upper surface of nasal bone with 4-16 small retrorse spines between nasal fossa and edge of premaxillary groove; often 2 or 3 small retrorse spines posteriorly on medial edge of nasal bone (premaxillary groove margin); 2 long opercular spines, the lower about 3/4 length to nearly as long as the upper spine; preopercular spine, 4.45-6.6 in HL; ridge at upper edge of suborbital bones serrate, the serrae decreasing in size posteriorly; 3rd or 4th dorsal spine longest, 1.9-2.25 in HL; 3rd anal spine 1.35-1.6 in HL; rounded caudal fin lobes (Ref. 27370).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 5.7 - 20.9, mean 16.9 (based on 47 cells; Ref. 115970).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.00784 - 0.03354), b=2.97 (2.80 - 3.14), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.66 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (16 of 100) .
