Indo-Pacific: East Africa, including the Mascarene Islands (Ref. 37792) to the Tuamoto Islands, north to Ryukyu Islands, south to southern Great Barrier Reef. Not occurring in the Red Sea.
Length at first maturity / Bộ gần gũi / Khối lượng (Trọng lượng) / Age
Maturity: Lm 18.4  range ? - ? cm
Max length : 45.3 cm FL con đực/không giới tính; (Ref. 125599); Khối lượng cực đại được công bố: 2.7 kg (Ref. 125599)
Các tia vây lưng cứng (tổng cộng) : 9; Các vây lưng mềm (tổng cộng) : 25 - 28; Tia cứng vây hậu môn: 3; Tia mềm vây hậu môn: 23 - 26. Color in life dark brown without lines on body or spots on head (one phase is purplish grey); horizontal black band behind upper gill opening absent on juveniles <6 cm SL; elongate purple band may be present anterior to dorsal origin; caudal fin brown; outer third of pectoral fin pale. Species with gizzard-like stomach.
Occurs in clear lagoon and seaward reefs around isolated coral heads. Solitary or in small groups (Ref. 90102). Prefers sandy bottoms of bays and lagoons rather than the coral reefs like most other Acanthuridae. The species is sometimes poisonous (Ref. 4795). Caught with nets (Ref. 30573). Minimum depth reported taken from Ref. 128797.
Probably spawn in pairs (Ref. 240).
