Etymology: Thalassoma: Greek, thalassa = the sea + Greek, soma = body; the colour of the sea (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; non-migratory; depth range 1 - ? m (Ref. 58302), usually 5 - 25 m (Ref. 27115). Tropical; 22°C - 26°C (Ref. 27115); 30°N - 15°N
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 6 - 12 cm
Max length : 28.0 cm TL male/unsexed; (Ref. 3921)
Eastern Central Pacific: Johnston (Ref. 11013) and Hawaiian islands.
Occur in clear lagoon and seaward reefs (Ref. 9710). Benthopelagic over coral, rock and rubble (Ref. 58302). Feed mainly on benthic animals. Juveniles and adults sometimes act as cleaners (Ref. 9710). Spawning occur either in aggregations by fish in the initial color phase or in pairs, typically with the terminal male being much larger than the female.
