Etymology: Thalassoma:Greek, thalassa = the sea + Greek, soma = body; the colour of the sea (Ref. 45335). More on author: Linnaeus.
Ambiente: milieu / zona climática / intervalo de profundidade / gama de distribuição Ecologia
marinhas associadas(os) a recifes; intervalo de profundidade 1 - 20 m (Ref. 9823), usually 1 - 20 m (Ref. 27115). Subtropical; 24°C - 28°C (Ref. 27115); 32°N - 36°S, 24°E - 136°W
Indo-Pacific: Red Sea and East Africa (Ref. 4392) to the Line Islands, north to southern Japan, south to Lord Howe Island and northern New Zealand (Ref. 1602). Reported to have formed a hybrid with Thalassoma rueppellii (Ref. 41655).

Espinhos dorsais (total) : 8; Raios dorsais moles (total) : 13; Espinhos anais: 3; Raios anais moles: 11. Adults are identified by the yellow lunate tail. Large males turn blue on the head that grades to green towards the tail (Ref. 48636). Body dark green to blue with vertical red to purplish red lines. Head green to blue with irregular pink to violet bands. Adults with large yellow crescent posteriorly in caudal fin and blue pectoral fins with a large elongate pink area distally. Juveniles with a large dark spot in middle of dorsal fin and a large diffuse black spot at base of caudal fin (Ref 9823). Body shape (shape guide): fusiform / normal; Cross section: compressed.
Occurs solitary or in groups (Ref. 90102) in the upper portions of lagoon and coastal reefs, and in protected seaward reefs (Ref. 1602). Enters estuaries (Ref. 48636). Usually found on upper portions of ledges and heads (Ref. 9710). Feeds mainly on small benthic invertebrates and fish eggs (Ref. 9823). A protogynous hermaphrodite (Ref. 55367).
