生态学
海洋 礁区鱼类; 深度上下限 0 - 40 m (Ref. 9813), usually 1 - 30 m (Ref. 27115). 熱帶; 25°C - 29°C (Ref. 27115); 30°N - 30°S, 32°E - 128°W
Indo-Pacific: Red Sea and East Africa to Pitcairn. Often the only siganid present on remote islands like Pitcairn, Rapa and Line.
印度-太平洋: 紅海而且東非到皮特凱恩島。 經常是唯一的藍子魚位於像皮特凱恩島，拉帕島與列島群島的離島之上。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm ?, range 20 - ? cm
Max length : 40.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 9813); common length : 25.0 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: 13. This species is distinguished by the following characters: juveniles and adults with body oval and compressed, slender, fusiform, greatest body depth 2.4-3 in SL; anterior nostril with a long flap reaching to or past posterior nostril; last dorsal-fin spine very short, 2.6-3.5 times in longest dorsal-fin spine; last anal-fin spine shortest, 2.1-3.1 times in longest (second or third) anal-fin spine; caudal fin deeply forked. Colour of body blue or greyish above, silvery below; variations in markings (spots, curved lines); head and trunk usually covered with small yellow spots, bars, and commas, much larger than interspaces and quarter to 1/2 size of pupil; spots usually joining to form horizontal wavy lines, particularly on lower sides; yellow pectoral-fin axil, usually yellow stripes along base of dorsal fin and a dark brown bar immediately posterior to the upper opercular margin; colours fade rapidly at death so that head and trunk may be solid brown (Ref. 9813, 90102).
身体蓝色的上方, 下面银色的; 斑纹 (斑点, 曲线) 的变化出现。 银黄色的虹膜。 当被惊吓时，否则睡熟了又整个的鱼变成具有非常淡色与深色的褐色色斑, 有深色的在侧边对面的 7个斜的区域中成为主流的一些; 鳍变成有斑点。 棘细长的，尖锐的，和有毒的。 前鳃盖骨角 85 °-95 °. 在颊上的细的鳞片。 胸的中线没有鳞片。 表面地与 S. canaliculatus 与 S. fuscescens 相似, 特别地幼年时, 但是不同之处为有一个更加深深地分岔尾部.(参考文献 1602)
Inhabits coastal and inner reef slopes and lagoons. Usually occurs in large schools that swim fast and well above the substrate, occasionally all diving down to the bottom to feed (Ref. 48637). Juveniles and adults occur in small schools (2-100) around coral reefs, typically in surge zone at reef edge. Juveniles live near the surface in dense aggregations up to several km offshore, migrating to reef flats just prior to metamorphosis. Feeds on algae (Ref. 30573). Juveniles and adults not frequently found in markets; but prejuveniles form a brief but important fishery when migrating on to the reef flat, e.g. combined catch (with Siganus spinus of 16 tonnes in one season in Guam. Prejuveniles eaten fresh, pickled in brine or made into fish paste (Ref. 9813). Consumed as food although it is known to be occasionally poisonous (Ref. 4537). Used in Chinese medicine (Ref. 12166).
栖息于海岸而内部的礁斜坡与舄湖。 通常大群鱼群出现以快速地游动而且在底部上面一些的水域，偶然所有的潜水向下至底部觅食.(参考文献 48637) 稚鱼与成鱼珊瑚礁的周围形成小群鱼群 (2-100), 在礁边缘典型地形成涌浪区。 稚鱼生活在接近水表处形成密集的群集达到被在正要锐变之前洄游至礁石平台的几公里外海。 吃藻类.(参考文献 30573) 稚鱼与成鱼不时常发现于市场了; 但是前期幼生形成一个摘要但是重要的渔场当在到礁石平台上移动的时候，例如联合了捕捉 (在一个季节内具有 16个公吨的 Siganus spinus 在關島。 被生鮮食用的前期幼生, 鹽水醃漬或製成了魚漿.(參考文獻 9813) 被當作食物雖然它被知道偶然有毒.(參考文獻 4537) 被用於中藥材了。 (參考文獻 12166)
