Main Ref. van der Elst, R.P. and F. Adkin (eds.), 1991
Remarks Occurs off sandy beaches, rocky shores and in shallow bays (Ref. 5578). Feeds on crabs, lobsters, bony fish and small sharks (Ref. 5578). Forms schools in summer (Ref. 244). Hardy and keeps well in captivity (Ref. 244). Commonly caught by rock and surf sports anglers but not eaten much (Ref. 244).
