Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 31-33; Anal spines: 3; Anal soft rays: 23 - 25. Pale gray around mouth, and pale gray margin on caudal fin. Inside of pectoral fin yellow (Ref. 26938). Juveniles are black with two light yellow bars on body and three on head; caudal fin yellow with a vertically elongate, nearly rectangular or hemispherical black spot in middle (Ref. 13442).

Common in coral reefs, usually solitary, occasionally in pairs. Juveniles are part-time cleaners. Feed mainly on sponges, but also takes tunicates, algae, zoantharians, gorgonians, hydroids, bryozoans, and seagrasses. Oviparous (Ref. 240), monogamous (Ref. 52884). Flesh reported to be of excellent quality (Ref. 3797); marketed fresh and salted (Ref. 5217). Friendly toward divers (Ref. 9710). Have been reared in captivity (Ref. 35419).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.03236 (0.01768 - 0.05924), b=2.92 (2.76 - 3.08), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.2 ±0.1 se; Based on diet studies.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Moderate to high vulnerability (51 of 100) .

Price category (Ref. 80766): High.
