Body shape (shape guide): fusiform / normal.
Occurs over sandy (Ref. 2683) and muddy bottoms in shallow waters (Ref. 4340), frequently in brackish habitats (Ref. 4340, 57402) and estuaries, but not in freshwaters (Ref. 57402). Feeds on benthic invertebrates (Ref. 5377). Sold fresh, dried salted or smoked (Ref. 36127).
