Short description Morfología | Morfometría

Espinas dorsales (total): 11; Radios blandos dorsales (total): 10-11; Espinas anales 3; Radios blandos anales: 8. Reddish, bronzy or golden-yellow in color; young with a blotch behind dorsal fin.

Biología     Glosario (por ej. epibenthic)

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.
