Occurs in shallow muddy bottoms from the coastline to 75 m depth; also in brackish estuaries and hypersaline lagoons (Ref. 5217). Inhabit mainly coastal waters and tidelands, but abundant in waters very near the sea to a few meters elevation with wholly freshwater ichthyofauna (Ref. 36880). Feeds mainly on zooplankton and zoobenthos (Ref. 13196). Taken with beach nets (Ref. 5217).
