|Species EnvironmentBenthopelagic species (depth range 0-400 m). Generally over muddy bottoms of shallow coastal waters. Often enters estuaries. Juveniles feed mostly on small pelagic planktonic crustaceans and small fishes; adults feed mainly on fishes and occasionally on squids and crustaceans. Adults and juveniles have opposing complementary vertical diurnal feeding migration. Large adults usually feed near the surface during the daytime and migrate to the bottom at night. Juveniles and small adults form schools 100 m above the bottom during the daytime and form loose feeding aggregations at night near the surface.|
