The goliathgrouper is the largest of the grouper in the western Atlantic, possibly reaching 8 ft (2.5 m) and a weight of 1000 lb (455 kg). The body, including the head and fins, is mottled with dark brown blotches and blackish spots.

The Atlantic goliathgrouper or Tamara (Epimetheus Tamara), also known as the Jewish, is a large saltwater fish of the grouper family found primarily in shallow tropical waters among coral and artificial reefs at depths from 5 to 50 m (16 to 164 ft). Its range includes the Florida Keys in the US, the Bahamas, most of the Caribbean and most of the Brazilian coast.

On some occasions, it is caught off the coasts of the US states of New England off Maine and Massachusetts. In the eastern Atlantic Ocean, it occurs from the Congo to Senegal.

Young Atlantic Goliath groupers may live in brackish estuaries, oyster beds, canals, and mangrove swamps, which is unusual behavior among groupers. They may reach extremely large sizes, growing to lengths up to 2.5 m (8.2 ft) and can weigh as much as 360 kg (790 lb).

The world record for a hook-and-line-captured specimen is 308.44 kg (680.0 lb), caught off Fernanda Beach, Florida, in 1961. Considered of fine food quality, Atlantic goliathgrouper were a highly sought-after quarry for fishermen.

It is a relatively easy prey for spear fishermen because of the grouper's inquisitive and generally fearless nature. They also tend to spawn in large aggregations, returning annually to the same locations.

This makes them particularly vulnerable to mass harvesting while breeding. Until a harvest ban was placed on the species, its population was in rapid decline.

The fish is recognized as “vulnerable” globally and “endangered” in the Gulf of Mexico. The species' population has been recovering since the ban; with the fish's slow growth rate, however, some time will be needed for populations to return to their previous levels.

Goliath groupers are believed to be protogynous hermaphrodites, which refer to organisms that are born female and at some point in their lifespans change sex to male. Males can be sexually mature at about 115 centimeters (45 in), and ages 4–6 years.

In May 2015, the Atlantic goliathgrouper was successfully bred in captivity for the first time. Tidal pools act as nurseries for juvenile E. Tamara.

In tidal pools juvenile E.Tamara are able to utilize rocky crevices for shelter. Besides shelter, tidal pools provide E. Tamara with plenty of prey such as lobster and porcelain crab.

The Atlantic goliathgrouper has historically been referred to as the “Jewish”. It may have referred to the fish's status as inferior leading it to be declared only suitable for Jews, or the flesh having a “clean” taste comparable to kosher food ; it has also been suggested that this name is simply a corruption of jaw fish or the Italian word for “bottom fish”, Giuseppe.

Despite clear and promising signs of recovery in us waters following the 1990 moratorium, the will increase in numbers noted area unit young and juvenile fish (the species takes five to six years to become sexually mature).

The goliathgrouper occurs within the western Atlantic Ocean from Florida south to Brazil, including the Gulf of Mexico and also the Caribbean Sea. This marine fish inhabits shallow, inshore waters with mud, rock or coral bottoms and is infrequently found below depths of 46 meters.
