Red Mullet
From Cookipedia
Red mullets or surmullets are two species of goatfish, Mullus barbatus and Mullus surmuletus, found in the Mediterranean Sea, east North Atlantic Ocean, and the Black Sea. Both "red mullet" and "surmullet" can also refer to the Mullidae in general.
Despite the English name "red mullet", these fishes of the goatfish family Mullidae are not closely related to many other species called "mullet", which are members of the grey mullet family Mugilidae.
They are both favored delicacies in the Mediterranean, and in antiquity were "one of the most famous and valued fish". They are very similar, and cooked in the same ways. M. surmuletus is perhaps somewhat more prized.
