Etymology: Thalassoma: Greek, thalassa = the sea + Greek, soma = body; the colour of the sea (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range - 15 m (Ref. 2334), usually - 15 m (Ref. 27115). Tropical; 24°C - 28°C (Ref. 27115); 30°N - 32°S
Indo-Pacific: East Africa to the Line and Tuamoto islands, north to southern Japan, south to the Lord Howe and Austral islands.
Length at first maturity / Size / Weight / Age
Maturity: Lm 8.5  range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 48636); common length : 15.0 cm TL male/unsexed; (Ref. 6113)
soft rays: 11. Color pattern remains similar with growth with terminal males becoming gaudier than primary males (Ref. 37816). Pale green with 6 dark bars, last two as saddles over the tail. Head with pink bands radiating from eye in large adults (Ref. 48636).
Occurs in shallow lagoon and seaward reefs, slopes and along drop-offs to moderate depths. Occurs in small, loose groups (Ref. 48636). Feeds on benthic and planktonic crustaceans, small fishes, and foraminiferans.
