Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 9. White stripe above upper dark stripe ends at gill opening; upper and lower caudal margins pale (Ref. 26938). Terminal phase males are blue-green and orange, chest and head pink below a green band at lower edge of eye; median fins with blue borders, the broad central parts orange with linear blue markings (Ref. 13442).

Biology     Glossary (e.g. epibenthic)

Found over shallow, clear waters, generally over Thalassia beds (Ref. 13628). Also found rocky or coral areas (Ref. 13628). A schooling species. Feeds on plants. A protogynous hermaphrodite (Ref. 55367). Super males spawn individually with striped females, while sexually mature males in the striped phase spawn in aggregation.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00699 - 0.01720), b=3.02 (2.89 - 3.15), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.0   ±0.0 se; Based on diet studies.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (17 of 100) .
Price category (Ref. 80766):   High.
