Inhabit inshore on coastal muddy or sandy habitats in still bays, and commonly found in harbours and estuaries. Small juveniles on protected shallow mudflats (Ref. 48637). Found in weedy areas near rocks or reefs. Juveniles often near river mouths and in brackish water. Adults are solitary, juveniles often form small groups (Ref. 1602). Large adults are shy (Ref. 48637). Feed on benthic invertebrates by blowing away the sand (Ref. 1602). Readily dried and used to make ornaments (Ref. 12484).
