生物学     用語集 (例 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).
