大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 45.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 48637); 最大年龄: 35 年 (Ref. 52229)
背棘 (总数) : 9; 背的软条 (总数) : 25 - 27; 臀棘: 3; 臀鳍软条: 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).
颜色活着时趋向形成不规则的纵向线的蓝灰色的有很多的土黄色斑点; 头部有狭窄的不规则的斑纹; 在眼一个黄斑后面; 褐色胸鳍; 尾鳍基底有白色的横带。 尾棘大的,3- 4.4 头长比率。 腹部像砂囊一样的。 有别于 A. dussumieri 藉着具有垂直的斑纹取代在尾鳍的蓝色中央区域上的斑点, 从 A. mata 藉由有一个新月状的尾鳍, 而且从 A. xanthopterus 藉着具有全褐色的对蓝灰色胸鳍.(参考文献 1602) 白色的环尾部的基底的周围改变色彩而且可能偶然地缺席。 (参考文献 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).
出现于舄湖外部与临海礁石, 通常在一些大洋性的地点中在小群鱼群与鱼群中见到.(参考文献 48637) 主要吃海藻的薄膜密实的覆盖在沙上, 摄取一般沙子的成分可能在薄的胃壁中帮助磨碎海藻的食物, 也吃硅藻与碎屑.(参考文献 3921)
