Dorsal spines (total): 13; Dorsal soft rays (total): 17-20; Anal spines: 3; Anal soft rays: 16 - 17. Large black spot surrounded by a white ring on body below rear of dorsal fin. Narrow, dark, diagonal lines that meet at mid-side, forming series of forward-pointing chevrons (Ref. 26938). Upper profile of head steep and slightly concave due to protruding snout; light gray, shading to pale yellowish on sides; a black bar on head; pelvic fins yellow (Ref. 13442).

Biology     Glossary (e.g. epibenthic)

Inhabit shallow reefs and generally occurs singly or in pairs. Feed mainly on zoantharians, polychaete worms, gorgonians and tunicates. Easily approached (Ref. 9710). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Form pairs during breeding (Ref. 205). Monogamous mating is observed as obligate, genetic and social (Ref. 52884).

Estimates based on models

Preferred temperature (Ref. 115969): 25.5 - 28.2, mean 27.4 °C (based on 558 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02512 (0.01646 - 0.03832), b=3.09 (2.96 - 3.22), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.0 se; based on diet studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (12 of 100) .
