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.
