More on authors: Quoy & Gaimard.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 30 m (Ref. 48636), usually 2 - 18 m (Ref. 89972). Tropical; 30°N - 32°S
Indo-Pacific: Christmas Island and Rowly Shoals in the eastern Indian Ocean to the Line and Ducie islands, north to south Japan, south to Lord Howe Island.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 27.0 cm TL male/unsexed; (Ref. 9710)
soft rays: 10 - 11. Light greenish to yellowish on back, white below; scale rims pink to blackish; a black spot is at the upper base of the pectoral fin; another black spot about equal to eye diameter is at the upper base of the caudal peduncle.
Inhabits sandy areas of reef flats, lagoons, and semi-protected seaward reefs. Juveniles shallow in protected coastal waters; adults to about 30 m depth (Ref. 48636). Feeds on sand and rubble dwelling invertebrates (crustaceans, mollusks, forams, polychaetes, fish eggs, and small fishes). Has the habit of following sand-disturbing fishes such as goatfishes in order to intercept escaping prey. Minimum depth reported taken from Ref. 30874.
