Occurs in shallow coastal waters (Ref. 1371). Enters rivers and may go considerable distances upstream, but usually remaining within regions of tidal influence (Ref. 1371, 27547). Adults exhibit seasonal movements: inshore during winter for purposes of spawning and offshore during summer for feeding (Ref. 1371). Juveniles and adults are opportunistic epibenthic feeders; juveniles feed on fish and small benthic crustaceans (Ref. 1371). Taxonomic problems to be solved.
