Etymology: Scarus:Greek, skaros = a fish described by anciente writers as a parrot fish; 1601 (Ref. 45335). More on author: Valenciennes.
Indo-West Pacific: Maldives to New Ireland in Papua New Guinea, including Cocos-Keeling Islands, north to Ryukyu Islands and south to the Philippines, including Palau. This species is the terminal male of Scarus singaporensis. Possibly replaced by Scarus falcipinnis in the western Indian Ocean (Ref. 2689). 印度-西太平洋: 馬爾地夫到巴布亞新幾內亞的新愛爾蘭, 包括可可群島-基靈群島, 北至琉球群島而且南至菲律賓,包括帛琉。 這種是 Scarus singaporensis 的末期的雄魚。 在西印度洋可能被 Scarus falcipinnis 取代。 (參考文獻 2689)

成熟度: Lm? range ? - ? cm Max length : 70.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 9710)
背棘 (總數) : 9; 背的軟條 (總數) : 10; 臀棘: 3; 臀鰭軟條: 9. Scales large. Median predorsal scales 6; 3 scale rows on cheek, with 1-3 scales in ventral row. Caudal fins emarginate in initial phase to deeply concave in large terminal phase. Lips nearly covering dental plates; terminal males with 0-2 canines posteriorly on side of upper plate, none on lower. The initial phase closely resembles that of S. altipinnis (Ref. 1602). The terminal phase has the distinctive brilliant green throat and lacks the filamentous middle dorsal spine (Ref. 1602). Body shape (shape guide): elongated; Cross section: compressed. 鱗片大的。 中央的前背鱗片 6; 在頰上的 3 鱗片列,在腹的列中 1-3個鱗片。 尾鰭邊緣微凹的在最初的階段中到深深地較大時凹曲最後階段。 唇幾乎包含的牙齒碟; 末期雄魚有 0-2 犬齒在上面碟的側邊後面, 下面沒有。 最初的階段非常近似 S. altipinnis 。 (參考文獻 1602) 最後階段有特殊的色彩豔麗的綠色咽喉而且缺乏絲狀的中央背棘。 (參考文獻 1602)
