背面の脊椎 (合計) : 11; 背鰭 (合計) : 10 - 11; 肛門の骨: 3; 臀鰭: 8. Reddish, bronzy or golden-yellow in color; young with a blotch behind dorsal fin.
Body shape (shape guide): fusiform / normal.
Found near rocky banks in coastal waters including estuaries. Adults solitary and territorial. Feeds on octopus, crabs and fish, especially Spondyliosoma. The flesh is highly esteemed, but the liver is poisonous due to high vitamin A content which causes hypervitaminosis. Popular angling fish. Largest of the porgies.
