背棘 (總數) : 5; 背的軟條 (總數) : 28 - 29; 臀棘: 2; 臀鰭軟條: 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).
一致褐色或橄欖色的顏色, 腹面灰白的; 亞成魚有黑色的尾部鰭條，狹窄的邊緣與白色的尾絲; 胸鰭有白色的末梢部的邊緣。 (參考文獻 3145)

生物學特性     字彙 (例如 epibenthic)

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).

稚魚出現在清澈的, 水淺的潟湖礁在深度淺到 1 公尺; 成魚很少在被見到外海的外圍礁石海峭壁的少於 25 公尺見到形成小群魚群。 吃大的浮游動物在白天期間而且躲藏在裡面礁夜晚時; 也水底的藻類.(參考文獻 30573)
