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.

Scientists from our Southeast Fisheries Science Center are working to understand the changes that have occurred in coral reef ecosystems following the loss of top predators, such as groupers. The once common Nassau grouper (Epimetheus stratus) and goliathgrouper (E. Tamara) have been so depleted that they are under complete protection from the South Atlantic, Gulf of Mexico, and Caribbean.

From 1997-2005, our researchers collaborated with Florida State University's Institute for Fishery Resource Ecology (Dr. Chris Koenig and Dr. Felicia Coleman) to monitor the status and recovery of goliathgrouper. This goliathgrouper research program investigated juvenile and adult Jewish abundance, distribution and migration patterns; their age and growth; and their habitat utilization.

With the help of Don Maria we have tagged over 1,000 adult Jewish and have observed aggregations of goliathgrouper in both the Gulf of Mexico and more recently, the South Atlantic. Posters created by the Center of Marine Conservation help disseminate information about our project and its requirements, highlighting our tagging study and the morphology of goliathgrouper.

Given that these groupers were afforded protected status, researchers worked to utilize and develop novel non-lethal techniques to procure and analyze biological samples for life history information. These casualties, resulting from red tide, gave our biologists a unique opportunity to collect a multitude of biological samples, without having to sacrifice healthy animals.

From these decomposing carcasses, biologists were able to record length for use in an age/length relationship, and were able to extract monoliths and remove dorsal spines and rays for comparison of hard parts in age and growth analysis. Tissue samples were also removed and sent to the Florida Marine Research Institute, so they could evaluate the level of red tide toxin.

The sampling trip gave these biologists an opportunity to educate the curious beach goers about red tide and goliathgrouper (a few of which had been misidentified as baby manatees). Attempts to evaluate the data needed to assess the status of these depleted stocks and develop rebuilding plans present unique challenges.

In 2010, the Florida Fish and Wildlife Conservation Commission and NOAA Fisheries convened a benchmark goliathgrouper assessment for the continental U.S. population. This project would not have been possible without ongoing collaboration with researchers from Florida State University, Everglades National Park, and the recreational fishing and SCUBA diving communities.

The goliathgrouper inhabits tropical and subtropical waters and can be found in the eastern Pacific, western Atlantic, and eastern Atlantic Ocean from Florida to Brazil, the Caribbean Sea, and the Gulf of Mexico in shallow reefs at depths from 15 feet to 150 feet. Adults have small spots on the fins, body and head and are typically olive, gray or brownish yellow in color.

Goliath groupers are opportunistic ambush predators that feed on a variety of food items. This grouper primarily feeds on crustaceans (crabs, shrimp and spiny lobster).

Other prey items include octopus, juvenile sea turtles, gastropods, and a variety of fish such as hard head catfish, stingray and parrot fish. The fish take several years to reach sexual maturity due to the slow growth rate.

Males are considered sexually mature when they have reached a total length of 45.5 inches and are over seven years of age. Females are considered sexually mature when they reach a total length of 48.2 inches and are over six years of age.

In the Gulf of Mexico spawning occurs during a full moon in July through September. Research has shown slow-growing, long-lived, fish which aggregate in specific spawning sites are vulnerable to overfishing.

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. Furthermore, its meat stands out for its nutritional value and renowned taste, similar to that of the common grouper.
