Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 12-14; Anal spines: 4; Anal soft rays: 9 - 10. Body with red and white stripes following the scale rows; black blotch at base of soft dorsal, anal, and caudal fins, but may be faint or absent in caudal and anal fins (Ref. 4201, 48635). Uniformly small ctenii on posterior margin of scales of body. Inferior mouth due to hypertrophy of median part of upper lip (front of upper lip thickened and slightly protruding) (Ref. 3079). Five oblique scale rows on cheek; body depth 2.7-2.95 in SL; head length (HL) 2.6-2.9 in SL; snout length 3.6-4.4 in HL; interorbital width 4.4-5.25 in HL; slender caudal peduncle, depth 3.9-4.65 in HL; maxilla extending from below center of the eye to a vertical at rear edge of pupil, upper jaw length 2.25-2.4 in HL; premaxillary groove ending above or slightly posterior to a vertical at the front edge of orbit; anterior end of nasal bone ending with a small spine; surface or medial edge of nasal bone spineless; nasal fossa with 1 to 4 spinules on posterior edge; preopercular spine 3.45-3.65 in HL; longest dorsal spine 1.95-2.4 in HL; 3rd anal spine 1.5-1.75 in HL (Ref. 27370).

Biology     Glossary (e.g. epibenthic)

A relatively uncommon inhabitant of rocky reefs and coral-rich areas. Spine of preopercle venomous. Usually seen solitary , but sometimes forms schools in deep water in oceanic locations (Ref. 48635). Found in seaward slopes in 5-90 m (Ref. 90102).

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=0.01622 (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 (19 of 100) .
