Adults are found on shallow mud or mud-sand bottoms in turbid and generally brackish water near estuaries (Ref. 13628). Also encountered in weedy backwaters (Ref. 7251) and hyper-saline waters (Ref. 13628) with salinity ranging from 0.15 to 37.2 ppt (Ref. 97140).
栖息于水浅的泥或泥-沙底部了在浑浊的与通常在河口附近的半淡咸水.(参考文献 13628) 也在杂草丛生的洄水区 (参考文献 7251) 与高盐度的水域中见到了。 (参考文献 13628)
