55 cm. Mediterranean to the Cape and round our coast to
Mozambique; recorded from Red Sea, but none found in
tropical east Africa. Not abundant; caught by anglers using
small hooks mainly in sandy areas of estuaries and down to
30 m; flesh excellent. Spawns in the sea during summer.

artist may hope to portray these colours in their natural
brilliance. Attains 50 cm. Known only from the Cape to
Sodwana Bay. Not often taken by shore anglers, then as a
rule only on rocky banks in rather deep water, chiefly on
redbait. Flesh excellent.

occasionally taken in fair numbers from deepish rocky
areas.
