簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 13; 背的軟條 (總數): 10; 臀棘 7; 臀鰭軟條: 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).
身體藍色的上方, 下面銀色的; 斑紋 (斑點, 曲線) 的變化出現。 銀黃色的虹膜。 當被驚嚇時,否則睡熟了又整個的魚變成具有非常淡色與深色的褐色色斑, 有深色的在側邊對面的 7個斜的區域中成為主流的一些; 鰭變成有斑點。 棘細長的﹐尖銳的﹐和有毒的。 前鰓蓋骨角 85 °-95 °. 在頰上的細的鱗片。 胸的中線沒有鱗片。 表面地與 S. canaliculatus S. fuscescens 相似, 特別地幼年時, 但是不同之處為有一個更加深深地分岔尾部.(參考文獻 1602)

生物學特性     字彙 (例如 epibenthic)

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).

稚魚與成魚珊瑚礁的周圍形成小群魚群 (2-100), 在礁邊緣典型地形成湧浪區。 稚魚生活被在正要銳變之前洄游至礁石平臺的在接近水表處形成密集的群集達到幾公里外海。 吃藻類。 (參考文獻 30573) 稚魚與成魚不時常發現於市場了; 但是前期幼生形成一個摘要但是重要的漁場當在到礁石平臺上移動的時候,例如聯合了捕捉 (在一個季節內具有 16個公噸的 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)
