Maturity: Lm ? range ? - ? cm
Max length : 14.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 4391); common length : 9.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5450)
背棘 (总数) : 12; 背的软条 (总数) : 15 - 17; 臀棘: 2; 臀鳍软条: 12 - 14. Diagnosis: Adults generally brown; dorsal part of head and nape darker, grading to tan on lower part of head and breast. The scales have darker brown margins. The lips are whitish lips; the suborbital is mostly blue; the preopercle and opercle scales with blue centers. The median and pelvic fins are brown; the pectorals are dusky; a well-defined dark brown or blackish spot is sometimes present at base of posteriormost dorsal rays, which distinguishes it from S. lividus where the spot is diffuse. Males in courtship or guarding eggs with broad white bar across middle of body and pale blue stripe from mouth to upper part of pectoral fin (Ref. 510).
成鱼通常褐色; 头部与后颈的背部部份比较深色的, 渐层色到黄褐色的在头部与胸部的较下面的部位上。 鳞片有较深色的褐色边缘。 唇是微白色的唇; 眶下骨大部份蓝色; 前鳃盖骨与鳃盖鳞片有蓝色的中心。 中动脉与腹鳍是褐色; 胸鳍是暗色的; 一很清晰深褐色或者黑色的斑点在最后面背鳍鳍条的基底有时候有, 可用来与斑点是扩散的 S. lividus 区别。 在求偶期或门卫鱼卵的雄性有宽的横过身体与胸鳍的蓝灰色斑纹从口部到上半部的中央的白色的横带。
Adults inhabit reef flats and lagoon reefs. Frequently occur in colonies associated with live or dead branching staghorn coral (Acropora). Feed on algae, gastropods, sponges, and copepods. Territorial, maintain and 'weed' filamentous algae patches growing on dead coral (Ref. 9710). They attack human intruders without hesitation, sometimes taking painful nips. Particularly aggressive during reproductive periods. The species emit clicking noises during aggressive encounters. Oviparous, males tend the nest visited by several females (Ref. 59295).
栖息于礁石平台与舄湖礁。 时常出现于中集群伴随着活或死的分枝鹿角珊瑚 ( Acropora)了. 吃藻类，腹足动物，海绵与桡脚类的动物。 领域性，维持与 '杂草' 菌丝藻区块生长在死珊瑚上.(参考文献 9710) 他们攻击没有暂停的入侵的人类, 有时咬一口令人疼痛。 特别具有侵略性在生殖的期间。 此鱼种在与侵略者遭遇的时候发出卡嗒声。

Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).印度-太平洋: 紅海而且東非到列島群島，馬貴斯群島與 Tuamoto 島, 北至琉球與博寧群島, 南至新加勒多尼亞與東加; 在密克羅尼西亞各處。 除了夏威夷群島.(參考文獻 7247)
