簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 9; 背的軟條 (總數): 10; 臀棘 3; 臀鰭軟條: 9. This species is distinguished by the following features: 5-7 (usually 6) median predorsal scales; 3 scale rows on cheek 1(5-7), 2(5-7), 3(1-4); pectoral-fin rays 13-15 (usually 14); conical teeth on side of dental plate, none in female and usually 2 on upper and 0-1 on lower of dental plates for terminal male; lips nearly covering dental plates; caudal fin slightly rounded to truncate in female and emarginate in terminal male. Colour of patch covering cheek and gill cover of male orange, wavy band/lines on snout and cheek, pectoral fins pale green; female grey or grey-brown with 2 pale stripes on belly (Ref. 9793, 90102).
雄性容易地辨識特徵為黃色的胸鰭與橘色的頰了。 雌性全灰色沿著腹部的區域有灰白的線.(參考文獻 48636) 最初的階段非常近似 S. globiceps S. psittacus 。 不同在腹的側邊中躺在鱗片列與鱗片的數字中。

生物學特性     字彙 (例如 epibenthic)

Found in silty coastal and offshore areas to 20 m deep (Ref. 90102). Inhabits rocky and coral reefs from tidal pools to at least 10 m deep. Form schools with 30 to 40 individuals. Grazes on benthic algae and corals (Ref. 2935). Reproductively active terminal males become bicolored (Ref. 37816).

棲息於岩石與珊瑚礁從潮池到至少 10 公尺深。 與 30 到 40個個體形成魚群。 啃食水底的藻類與珊瑚。 (參考文獻 2935) 生殖活躍期末期雄性變成雙色的。 (參考文獻 37816)
