Θαλασσινό(ά) Υφαλόφιλο(α); εύρος βάθους 0 - 6 m (Ref. 37792). Tropical; 2°N - 1°N
Western Pacific: Kapingamarangi Atoll, Caroline Islands. Possibly endemic of that atoll. Reports from other areas are likely misidentifications of the juvenile stages of Acanthurus pyroferus (J.E. Randall, pers. comm.), e.g. from Taiwan (Shao et al., 2008).
Μέγεθος / Βάρος / Age
Maturity: Lm ? range ? - ? cm
Max length : 28.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 37792)
Ραχιαίες άκανθες (συνολικά) : 8; Μαλακές ραχιαίες ακτίνες (συνολικά) : 26; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 24. Caudal fin lunate. Life colour unknown. Preserved specimen is dark brown with two small oval spots, one above and the other slightly behind the upper end of the gill opening, and a dark brown band at the base of the dorsal fin.
Found over sand and coral bottoms of clear channels (Ref. 9710). Juveniles probably occur on reef flats (Ref. 9710). Rare and not commercial (J.E. Randall, pers. comm.).
