The Atlantic goliath grouper or itajara (Epinephelus itajara), commonly known as the jewfish, is a large saltwater fish of the grouper family found primarily in shallow tropical waters among coral and artificial reefs at depths from 15 to 165 ft (4.6 to 50 m). Its range includes the Florida Keys, the Bahamas, most of the Caribbean, and practically all of the Brazilian coast, where they are known as mero. On some occasions, it is caught in New England off Maine and Massachusetts. In the eastern Atlantic Ocean, it occurs from Congo to Senegal. Young Atlantic goliath grouper may live in brackish estuaries, canals, and mangrove swamps, unusual behavior among groupers. Argyrosomus japonicus is a silvery to bronze-green colored fish which may grow up to 2 m in length. It is known as mulloway or jewfish in Australia and dusky kob in South Africa. The name jewfish refers to the large earstones, which are prized as "jewels" by some fishers.
