Western Atlantic: Bermuda, Florida (USA), Bahamas, and northeastern Gulf of Mexico to northern South America; throughout the Caribbean (Ref. 3802, 13628). Range probably extends to Brazil (Ref. 13628).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 16 - ? cm
Max length : 35.0 cm TL male/unsexed; (Ref. 9710); common length : 18.0 cm TL male/unsexed; (Ref. 3802)
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).
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.
