Maturity: Lm ? range ? - ? cm
Max length : 24.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 9710)
背棘 (总数): 9; 背的软条 (总数): 29-33; 臀棘 3; 臀鳍软条: 26 - 29. Dark brown, nearly black in color. Erectile spine (sharp and forward-pointing) on each side of caudal peduncle which folds down into a groove. Mouth small, snout noticeably extended. Light blue ring around chin and presence of spot of same color on gill cover at angle of gill opening. Dorsal fin with soft part having longer base than spinous part. Juveniles lack the large orange spot on caudal area.
深褐色的, 几乎黑色。 在进入一个凹槽之内摺叠下来的尾柄的每个侧边上的直立的硬棘 (锐利的而且朝向前面的)。 嘴小的, 吻显着地延伸。 下巴的周围浅蓝色环而且在鳃盖上有相同颜色的斑点在突出部位上鳃裂。 背鳍有软棘的部位超过硬棘的部分有较长的基底。 稚鱼在尾部的区域上缺乏大的橘色斑点。
Occurs in clear seaward reefs, usually in groups (Ref. 9710). Benthopelagic (Ref. 58302). Feeds on filamentous and small fleshy algae (Ref. 9267). Monogamous (Ref. 52884). Spine in caudal peduncle may be venomous. Size of metamorphosis from postlarva stage to juvenile is 6 cm (Ref. 9267). This species sometimes hybridizes with A. nigricans (Ref. 9808).
出现于清澈的临海礁石, 通常成群.(参考文献 9710) 吃丝状而小的肉质多的藻类。 (参考文献 9267) 一夫一妻的.(参考文献 52884) 在尾柄的棘可能是有毒的。 来自后期仔鱼阶段到稚鱼的锐变的大小是 6 公分。 (参考文献 9267) 这种有时与 A. nigricans 杂交。 (参考文献 9808)
