Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

Ραχιαίες άκανθες (συνολικά) : 5; Μαλακές ραχιαίες ακτίνες (συνολικά) : 28 - 29; Εδρικές άκανθες: 2; Μαλακές εδρικές ακτίνες: 27 - 28. Plain brown or olivaceous in color, paler below; subadults with black caudal rays, narrow margins and white caudal filaments; pectoral fins with white distal margins (Ref. 3145).

Juveniles occur in clear, shallow lagoon reefs at depths as little as 1 m; adults rarely seen in less than 25 m, encountered off outer reef drop-offs in small schools (Ref. 30573, 48637). Benthopelagic (Ref. 58302). Feeds on large zooplankton during the day and shelter within the reef during the night; also benthic algae (Ref. 30573, 48637).
