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. In 2001, the American Fisheries Society stopped using the term because of complaints that it was culturally insensitive.

CLOSED TO HARVEST OR POSSESSION IN THE SOUTH ATLANTIC EEA (FEDERAL WATERS) SINCE 1990. The Florida Fish and Wildlife Conservation Commission has provided additional guidelines on release techniques for Goliath grouper.
The Florida Fish and Wildlife Conservation Commission has provided additional guidelines on release techniques for Goliath grouper. At least one hooking device is required and must be used as needed to remove hooks embedded in South Atlantic snapper- grouper with minimum damage.
Descending Device Requirement: Requirement: A descending device is required to be on board and readily available for use on all vessels fishing for or possessing snapper- grouper species; Definition of a Descending Device: an instrument to which is attached a minimum of a 16 ounce weight and a length of line that will release the fish at the depth from which the fish was caught or a minimum of 60 feet. Since minimizing surface time is critical to increasing survival, descending devices shall be readily available for use while engaged in fishing.

The Goliath grouper reaches a length of 8 feet (240 cm) and the largest published weight is 1003 lbs. The base of the soft dorsal and anal fins are covered with scales and thick skin.
The juvenile Goliath grouper, which is less than 39 inches (100 cm), is tawny or yellowish-brown in color with irregular darker brown vertical bands. The larger adult fish is gray or greenish with pale blotches and smaller dark brown or blackish spots scattered over the upper part of its head, body and pectoral fins.
The goliathgrouper is capable of producing a loud booming noise, which may be used to defend territory or during courtship. The Goliath grouper feeds primarily on crustaceans, especially spiny lobsters, as well as turtles, fish and stingrays.
This species is an ambush hunter that feeds during the day, with increased activity during the low-light periods of dawn and dusk. This is accompanied by rapidly expansion of its jaws and flaring of the gill covers which create a vacuum that sucks the prey into its mouth.
The Goliath grouper occurs in the western Atlantic from Florida to southern Brazil, including the Gulf of Mexico and the Caribbean. Populations began to decline in the 1960s when recreational SCUBA divers would swim up to the fearless fish and spear it at close range.
This consists of a “threat display” to intruders by opening its mouth wide and shaking its body or producing a loud booming sound (see below). The Goliath grouper will travel many miles during one or two months each year to mate in huge spawning aggregations at traditional breeding grounds.
As the male approaches the female, its entire forebode, from the pectoral fins forward, turns pale, contrasting sharply with its dark rest of the body. The eggs hatch into transparent larvae that quickly develop long spines and a large mouth.
After drifting with the current for 25 to 45 days, the one-inch larvae settle to the bottom in shallow-water mangrove habitats where they hide while completing metamorphosis into juveniles. Little is known about juvenile growth rates, feeding behaviors, or habitat shifts as this grouper matures.
Due to short dive times at depths of 100 feet or more, there have been few recorded observations of the courtship of the Goliath grouper. It possesses a robust and elongated body, with a wide head in comparison to its small eyes.
What’s more, the base of the dorsal fin stands out as being covered with scales and thick skin. Its yellowish, grayish or olive-toned coloring with small spots help the Atlantic goliathgrouper blend into its environment.
The majority of these gigantic fish live in deep waters, near rocky areas with coral and mud. Their geographic location is, for the most part, the American coast from Florida down to southern Brazil.
It’s also worth pointing out that there are also Atlantic Goliath groupers living along the African coast from Senegal to the Congo. The enormous size of this fish, along with its great gastronomic value, make it a much sought-after catch for fishermen.
However, its slow growth and low reproduction rate make it one of the most susceptible species to extinction. The Atlantic goliathgrouper, whose scientific name is Epimetheus Tamara, is a grouper species characterized by its large dimensions.
The Atlantic goliathgrouper goes by several other names, including Jewish and Tamara and many local nicknames. Historically, its size has made it popular among fishers and merchants to the point that it became the object of recreational competitions.
