生物學特性     字彙 (例如 epibenthic)

Occurs in shallow coastal waters, over sandy and muddy bottoms, sometimes in brackish habitats (Ref. 57343, 81658). Enters estuaries (Ref. 57402), occasionally caught in fresh water (Ref. 57402, 81658). Very large specimens are only found in marine waters (Ref. 81658). Feeds on crustaceans and fishes (Ref. 10799, 81658). Flesh fairly tasteful (Ref. 57402).

出現於淺水域, 在半鹹淡的棲息地 (河口與潟湖) 在泥沙底上面.(參考文獻 4340) 吃甲殼動物和魚類。 (參考文獻 10799)
