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: 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).
身體銀灰色的上方, 下面銀色的; 觸覺橄欖綠色的在後頸與頭部的上表皮上; 被驚嚇後體色圖案具有色斑灰白的乳黃色而深褐色的; 通常魚在側線的起源正下方顯示一個深色的小區塊。 前鰓蓋骨角 89 °-96 °; 頰狀似無鱗片的但是對許多﹐細的﹐和深入的鱗片有時有少數的低 2/3之上; 胸的中線無鱗片的在腹鰭脊之間。 被一個低邊緣用向在後部的鰓蓋延伸的鰓蓋環繞的前鼻孔的邊緣; 鰓蓋變短隨著體型增大。 非常近似 S. fuscescens 但是不同之處為它的約略更尖的吻與比較長胸鰭 (1.1-1.3個 HL比率 vs.1.4-1.5 在 S. fuscescens 中).(參考文獻 1602) 彩色斑紋是類似 S. argenteus S. fuscescens.

生物學特性     字彙 (例如 epibenthic)

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).

S. fuscescens相反, 這種似乎容忍被在河口的鄰近區域裡面出現的更混濁的水域尤其在海草床周圍。 也出現離岸數公里在深且清澈的水域中。 稚魚在淺灣與珊瑚礁平臺中形成非常大群的魚群; 魚群大小隨著體型增大而減小, 成魚形成群體的 20個個體左右。 食草的, 吃水底的藻類與在某些程度上在海草上。 被當作食物; 而且有有毒的棘.(參考文獻 4537)
