大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 45.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 48637); 最大年齡: 35 年 (Ref. 52229)
背棘 (總數) : 9; 背的軟條 (總數) : 25 - 27; 臀棘: 3; 臀鰭軟條: 24 - 25. Color in life bluish grey with numerous yellowish brown spots which tend to form irregular longitudinal lines; head with narrow irregular stripes; behind eye a yellow spot; brown pectoral fins; base of caudal fin with white bar. Caudal spine large, 3 - 4.4 in head. Stomach gizzard-like. Differs from A. dussumieri by having vertical stripes instead of spots on the blue central area of the caudal fin, from A. mata by having a lunate caudal fin, and from A. xanthopterus by having plain brown to blue-grey pectoral fins (Ref. 1602). The white ring around the base of the tail varies in intensity and may occasionally be absent (Ref. 1602).
顏色活著時趨向形成不規則的縱向線的藍灰色的有很多的土黃色斑點; 頭部有狹窄的不規則的斑紋; 在眼一個黃斑後面; 褐色胸鰭; 尾鰭基底有白色的橫帶。 尾棘大的,3- 4.4 頭長比率。 腹部像砂囊一樣的。 有別於 A. dussumieri 藉著具有垂直的斑紋取代在尾鰭的藍色中央區域上的斑點, 從 A. mata 藉由有一個新月狀的尾鰭, 而且從 A. xanthopterus 藉著具有全褐色的對藍灰色胸鰭.(參考文獻 1602) 白色的環尾部的基底的周圍改變色彩而且可能偶然地缺席。 (參考文獻 1602)
Adults occur in outer lagoon and seaward reefs, usually seen in small groups and school in some oceanic locations (Ref. 48637). Benthopelagic (Ref. 58302). They feed primarily on the algal film covering compacted sand, ingesting the usual component of sand which probably aids in the trituration of the algal food in the thick-walled stomach, also feed on diatoms and detritus (Ref. 3921).
出現於潟湖外部與臨海礁石。 主要吃海藻的薄膜密實的覆蓋在沙上, 攝取一般沙子的成分可能在薄的胃壁中幫助磨碎海藻的食物, 也吃矽藻與碎屑.(參考文獻 3921)
