Head reddish-orange; body and fins black (Ref. 1602); characterized further by having ctenoid scales except cycloid on abdomen; scaleless head and nape with bristle-like papillae; complete pelvic fin frenum and basal membrane; longitudinal scale series 23-25; depth of body at level of pelvic fins 3.0-3.2 in SL (Ref. 90102).

Biology     Glossary (e.g. epibenthic)

Lives among branches of Stylophora coral. Monogamous (Ref. 52884). Usually in small groups, also found in lagoon and seaward reefs in 1-10 m (Ref 90102).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Bi-directional sex change has been confirmed for this species (Ref. 103751). Monogamous mating is observed as both obligate and social (Ref. 52884).

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 29, mean 27.9 °C (based on 902 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.3 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).
