Pectoral filaments 6 with tip of uppermost filament reaching to or slightly beyond level of posterior tip of upper part of pectoral fin (Ref. 41110).
身體均勻金銀色的; 偶然地有一些模糊的深色斑紋沿著縱向的鱗片列在側線上面與下面。 胸的絲狀突起 6 最上面的絲頂端延伸到或略超過胸鰭的上半部的後頂端的水平.(參考文獻 41110)
This schooling species occurs along sandy and rocky shorelines and over sandy lagoon bottoms, often in zones of turbulence (Ref. 9685). Benthopelagic (Ref. 58302). Often encountered in river mouths or brackish mangrove estuaries. Feeds mainly on crustaceans (shrimps and crabs), polychaete worms, other benthic invertebrates; also on teleosts (Ref. 9685). A lunar spawning rhythm occurs close to shore (Ref. 9685). Sexual maturity in males occurs at 12 to 15 cm (Ref. 9685). Subsequently undergoes sex reversal passing through a hermaphroditic stage, and become female between 18 and 24 cm (Ref. 9685). The potential of this species for aquaculture has been studied (Ref. 9685).
這群游性種出現沿著沙與岩石的海岸線與砂質潟湖底部之上, 常見於狂暴的區域中.(參考文獻 9685) 時常在河口或半鹹淡水紅樹林河口見到了。 主要吃甲殼動物 (蝦與螃蟹) ，多毛類的蠕蟲，其他的底棲無脊椎動物; 也吃硬骨魚.(參考文獻 9685) 達到至少 40 公分標準長度。 (參考文獻 9685) 產生一個陰曆的產卵節律接近海岸.(參考文獻 9685) 在雄性的性成熟發生於 12 到 15 公分。 (參考文獻 9685) 他們後來進行性轉換經過一個雌雄同體的階段, 而且成為在 18 與 24 公分之間的雌性。 (參考文獻 9685) 水產業的這種的潛能已經被研究。 (參考文獻 9685)
