Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 11.6, range 12 - ? cm
Max length : 40.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 108696); common length : 20.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 9813)
背棘 (总数) : 13; 背的软条 (总数) : 10; 臀棘: 7; 臀鳍软条: 9; 脊椎骨: 23. This species is distinguished by the following characters: body compressed, moderately slender, its depth 2.3-2.8 in SL; last anal-fin spine 1.2-1.5 times in longest anal-fin spine (usually the third); soft parts of dorsal and anal fins low, longest dorsal-fin ray 0.7-1 times in longest dorsal-fin spine; caudal fin almost emarginate in specimens under 10 cm standard length, forked in larger fish; 16-26 (rarely 27) scale rows between lateral line and bases of leading dorsal-fin spines. Colour of body highly variable, greenish grey to yellow brown with numerous (100-200) pearly blue to whitish spots on nape and trunk, match-head size on lower sides; 2-3 rows between first spine of dorsal fin and lateral line (area of eye would cover about 6 spots in this region), and about 10 rows between highest point of lateral line and base of first anal-fin spine; when frightened or injured, sides mottled light and dark brown and cream, creating 6 or 7 regularly spaced, dark diagonal zones with paler zones of similar width between them; dark eye-sized spot usually just behind upper end of gill opening, and a narrow bar along upper edge of gill cover (Ref. 9813, 90102).
身体银灰色的上方, 下面银色的; 触觉橄榄绿色的在后颈与头部的上表皮上; 被惊吓后体色图案具有色斑灰白的乳黄色而深褐色的; 通常鱼在侧线的起源正下方显示一个深色的小区块。 前鳃盖骨角 89 °-96 °; 颊状似无鳞片的但是对许多，细的，和深入的鳞片有时有少数的低 2/3之上; 胸的中线无鳞片的在腹鳍脊之间。 被一个低边缘用向在后部的鳃盖延伸的鳃盖环绕的前鼻孔的边缘; 鳃盖变短随着体型增大。 非常近似 S. fuscescens 但是不同之处为它的约略更尖的吻与比较长胸鳍 (1.1-1.3个 HL比率 vs.1.4-1.5 在 S. fuscescens 中).(参考文献 1602) 彩色斑纹是类似 S. argenteus 与 S. fuscescens.
Adults inhabit inshore, algae reefs, estuaries and in large lagoons with algae-rubble habitats. Mainly common on rocky substrates (Ref. 48637). In contrast to S. fuscescens, this species seems to tolerate more turbid waters, occurring within the vicinity of river mouths especially around seagrass beds. Adults also occur several kilometers offshore in deep, clear waters. Juveniles form very large schools in shallow bays and coral reef flats; school size reduces with size, with adults occurring in groups of 20 individuals or so. Herbivorous, feed on benthic algae and to some extent on seagrass. Fished by trawling and seine netting; bycatch in traps set in deep water and marketed fresh in very large numbers (Ref. 9813). Consumed as food; and have poisonous spines (Ref. 4537).
栖息于沿海地区，藻类礁，河口与较大时和藻类-碎石栖息地的舄湖。 主要常见于岩石的底部.(参考文献 48637) 与 S. fuscescens相反, 这种似乎容忍被在河口的邻近区域里面出现的更混浊的水域尤其在海草床周围。 也出现离岸数公里在深且清澈的水域中。 稚鱼在浅湾与珊瑚礁平台中形成非常大群的鱼群; 鱼群大小随着体型增大而减小, 成鱼形成群体的 20个个体左右。 食草的, 吃底部的藻类与在某些程度上在海草上。 被当作食物; 而且有有毒的棘.(参考文献 4537)
Multiple spawner (Ref. 1753). Larger fish may spawn more than once in a spawning season (Ref. 1753). Spawn in group (Ref. 240).印度-西太平洋: 波斯灣，阿曼灣，巴基斯坦，印度，斯里蘭卡，緬甸，泰國，新加坡，馬來西亞，印尼，巴布亞新幾內亞，菲律賓，柬埔寨，越南，中國南方部，台灣與西澳大利亞。 也已知來自琉球群島; 密克羅尼西亞的帛琉與雅普島 (參考文獻 1602) 與美拉尼西亞.(參考文獻 712)
