在身體上的側邊上銀色的有大約七條模糊的略帶桃色的橫帶; 腹鰭黃色.(參考文獻 13442)
Inhabits shallow coastal waters in open sandy and surf areas, seagrass beds, near reefs, and mangrove channels (Ref. 7251). Enters brackish water, sometimes even fresh water (Ref. 3722). May occur in small aggregations (Ref. 3722). Feeds on benthic invertebrates such as worms, clams, crustaceans (Ref. 3722); also feeds on insects (Ref. 9303). Often seen feeding in sand patches among reefs by thrusting its mouth into the sediment and expelling sand from the gill openings (Ref. 13442). Easily approached (Ref. 9710). Marketed fresh but not highly esteemed; also processed into fishmeal (Ref. 3722).
在礁的附近，在開放的沙與碎浪區域，海草床中棲息於沿岸淺水區, 與紅樹林峽道.(參考文獻 7251) 進入半淡鹹水, 有時甚至淡水.(參考文獻 3722) 可能形成小群魚群。 (參考文獻 3722) 吃底棲的無脊椎動物例如蠕蟲，蛤, 甲殼動物;(參考文獻 3722) 也吃昆蟲。 (參考文獻 9303) 時常出現藉由插入它的嘴進入沉澱物而且驅逐沙子從鰓裂覓食於在礁之中的沙子區塊。 (參考文獻 13442) 容易接近。 (參考文獻 9710) 在市場上銷售生鮮地了但是不是深受喜愛; 也加工成魚粉。 (參考文獻 3722)
