Short description Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 13-14; Anal spines: 3; Anal soft rays: 11. Body without longitudinal stripes. Initial phase body yellow with light vertical red lines. Terminal phase body abruptly blue to blue-green behind pink and green head. Reddish vertical lines on body. Pectoral fins yellow on basal half, blue to black distally (Ref 9823).

Occurs in groups (Ref. 90102) in clear outer lagoon and seaward reefs, over open sand and rubble as well as dense coral growth. Common is shallow exposed areas (Ref. 9710). Benthopelagic (Ref. 58302). Feeds mainly on shelled benthic invertebrates (crabs, shrimps, gastropods, bivalves, brittle stars, sea urchins), also on polychaete worms and fish eggs.

Estimates based on models

Preferred temperature (Ref. 115969): 24.3 - 28.9, mean 27.5 (based on 1148 cells).

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00606 - 0.01650), b=3.05 (2.91 - 3.19), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.7 ±0.4 se; Based on diet studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (35 of 100) .

Price category (Ref. 80766): Very high.
