身體淺灰色又沒有斑紋或斑點。 在下頜發展良好的上的唇。 齒骨齒侷限於背面了。 顎骨不覆蓋著鱗片了。 胸的絲狀突起 6; 長的不超過臀鰭基底的後端的水平。 側線在被延伸至上、下尾鰭葉的後緣的尾鰭薄膜上分叉了。 有泳鰾.(參考文獻 45049)
Found in shallow water near the coast, on sand and mud bottoms (Ref. 9332). Larvae and small juveniles (>4 cm) are pelagic and sometimes occur several hundred kilometers offshore, whereas the larger juveniles and adults prefer shallow near-shore waters like bays, sloughs or estuaries where the bottom is sandy or muddy (Ref. 28023). Omnivorous, feeds on worms, sand crabs, shrimp, clams; sometimes feeds on fish like small anchovy (Ref. 28023). Esteemed food fish where it occurs (Ref. 57343). Also Ref. 55763.
在沙與泥底部上,發現於在海岸附近的淺水區.。 (參考文獻 9332) 仔魚與小的稚魚 (>4 公分) 是大洋性的而且有時出現幾百個公里外海, 然而較大的稚魚與成魚偏愛水淺的像底部是沙或泥濘的海灣，泥坑或者河口的近岸水域。 (參考文獻 28023) 雜食性,吃蠕蟲，沙子螃蟹，蝦，蛤; 有時吃像小的鯷魚魚。 (參考文獻 28023) 讚賞食用魚在那裡它出現.(參考文獻 57343) 也參考文獻 55763.
