Any of several large fishes of the sea bass family (Serranidae), especially Epinephelus itajara , found on the Atlantic coast of the New World tropics.
They may reach a length of 8 ft (2.4 m) and a weight of about 700 lbs (320 kg). The adult is dull olive-brown with faint spots and bands and is usually solitary. The South Pacific jewfish ( E. lanceolatus ) may exceed 12 ft (3.7 m) in length. The Warsaw grouper ( E. nigritus ) and giant sea bass ( Stereolepis gigas ) are both occasionally called jewfish, and three Australian species in the genera Johnius and Glaucosoma are called jewfish.
