Inhabits shallow coastal waters, estuaries and bays, over sand and mud bottoms, down to 84 m. Often in schools, except for large individuals that are solitary. More or less pelagic, but feeds on benthic worms, crustaceans and mollusks. Tolerates oxygen poor water by inhaling air into a lung-like airbladder.
