Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 9; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 8; Vertebrae: 23. This species is distinct with the following characters: D IX, 10; A III, 8; pectoral rays 12; 14+6 lateral-line scales; 15-17 gill rakers; body depth 3.0-3.3 in SL; head length (HL) 2.35-2.4 in SL; snout length 3.2-3.25 in HL; interorbital width 4.5 in HL; longest dorsal spine 2.15 in HL; third anal spine 2.05 in HL; pectoral-fin length 2.2 in HL; pelvic-fin length 2.15 in HL; when fresh it is purplish red posteriorly, grading to orange-red anteriorly; the snout and ventral part of head usually light blue-green; across body with 3 narrow white bars, the first from below second dorsal spine to abdomen, the second from eighth dorsal spine to third anal spine, the third across caudal peduncle; from nape across head behind eye runs a slightly oblique narrow bar, a faint white line extending ventrally from anterior edge of orbit; anteriorly on soft portion of dorsal fin is an ocellated black spot as large as eye; a short oblique narrow white band from middle of soft portion of dorsal fin onto back; anteriorly on soft portion of anal fin is a small elliptical ocellus; bluish white pelvic fins with a very large black spot; no blackish spot ventrally on abdomen between pelvic fins (Ref. 75144).
Found in coral reefs but secretive (Ref. 90102).

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=0.02188 (0.00887 - 0.05395), b=2.97 (2.76 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.4 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 (10 of 100).
