成熟度: Lm ? range ? - ? cm
Max length : 38.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 55); common length : 30.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5450); 最大年齡: 31 年 (Ref. 34051)
背棘 (總數) : 10; 背的軟條 (總數) : 13 - 15; 臀棘: 3; 臀鰭軟條: 8. Dorsal profile of head steeply sloped. Preorbital width usually less than eye diameter. Preopercular notch and knob well developed. Scale rows on back rising obliquely above lateral line. Generally bright yellow, including fins, with a series of blue stripes on the side. A round black spot, about the size of the eye or larger, is below the anterior most soft dorsal rays, touching the lateral line but mostly above it (Ref. 469). Body depth 2.3-2.9 in SL (Ref. 90102).
Body shape (shape guide): fusiform / normal; Cross section: oval.
頭部的背面輪廓非常陡峭。 眶前骨寬度通常少於眼直徑。 前鰓蓋骨凹槽與癤瘤發展良好的。 鱗片列背面斜向上升在側線上面。 通常鮮黃色的, 包括鰭, 側邊上有一系列的藍色斑紋。 一個圓的黑色斑點, 大小大約等於眼或比較大的, 在最前面的軟背鰭鰭條之下, 碰觸側線但是大部份在它上面。
Adults inhabit sheltered lagoons and exposed, outer slope coral reefs. Frequently encountered in large aggregations including 100 or more individuals at moderate depths, usually in 30-40m, like in some Pacific locations (Ref. 48635). Juveniles solitary and shallow in protected bays with algae and rubble substrates. They feed mainly on fishes and crustaceans (Ref. 4533).
棲息於有掩蔽的潟湖與暴露的,外部的斜坡珊瑚礁。 時常較大時見到了群集包括 100個或更多個體。 用藻類與碎石底部的稚魚獨居性與在遮蔽的內灣中的淺水處; 大的成魚形成小群魚群在深度中等之處, 通常在 30-40 公尺。 在一些太平洋的地點中形成大群魚群。 (參考文獻 48635) 主要吃魚與甲殼動物。 (參考文獻 4533)
