Found more abundantly on shallow soft bottoms of brackish estuaries or hypersaline lagoons. Enters freshwaters at least to an elevation of 10 m. Inhabits rivers and creeks and probably feeds on aquatic insects and crustaceans (Ref. 36880).
在半鹹淡河口或高鹽度的潟湖水淺軟質底部上更大量發現。 進入淡水至少到海拔 10 公尺。 棲息於河與小溪而且可能吃水生昆蟲與甲殼動物。 (參考文獻 36880)
