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.

Wikimedia Commons has media related to Epimetheus Tamara. Its range includes the Gulf of Mexico and Florida Keys in the United States, the Bahamas, most of the Caribbean, and most of the Brazilian coast.

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 Atlantic goliathgrouper, like most groupers, is an ambush predator and eats fairly large fishes and invertebrates and even small sharks. Throughout most of the year, low numbers of the Atlantic Goliath groupers are observed in any one place.

However, during reproduction (immediately after the full moons between June and December), they come together in groups of at least 100 individuals. These groups are known as spawning aggregations, and they form at relatively few places throughout the species’ range.

Though they were likely naturally rare, scientists believe that destructive fishing practices have reduced the numbers of the Atlantic Goliath groupers by at least 80% and that the species is now critically endangered. Furthermore, a total lack of fear of people makes them an easy target for spear fishers.

Finally, the Atlantic goliathgrouper ’s large size, slow growth, and ease of capture all contribute to slow its recovery, even where laws have been put in place to give it some or complete legal protection from fishing (e.g., in the USA and Brazil). It is important to continue to monitor Atlantic goliathgrouper population trends in order to determine whether the species is recovering or if stronger legal protection may be required.

Scientists only recently divided the species into two, based on their slightly different genetic makeup. The two species are similar in both appearance and behavior, but little is known about the population trends or conservation status of the Pacific goliathgrouper.

Goliath grouper occupies a wide geographic range, from Florida, including the Gulf of Mexico, Bahamas, and Caribbean Sea, south to Brazil. It is also found in both the eastern Pacific and eastern Atlantic from Senegal to the Democratic Republic of the Congo; however, it is rare in the Canary Islands.

Based on a study done by Craig et al. (2009), results suggest that there are genetic differences between populations of goliathgrouper in U.S. waters and those near Belize and Brazil. This species of grouper tends to be easily recognizable, in part, because it is the largest grouper species in western Atlantic waters.

Its body is brownish yellow, gray or olive colored with irregular dark bars on its sides and small spots mostly on its head and fins. The goliathgrouper has a very broad head with small eyes; the spiny dorsal fin is very low, and much shorter than the second dorsal fin.

Juveniles are a yellowish-orange color with dark irregular vertical bands and blotches on their sides. The adult goliathgrouper lives in shallow waters up to 328 feet (100 meters) 6, over wrecks, corals or muddy or rocky bottoms.

This is one of the few grouper species also found in brackish water habitats. Adults are territorial and occupy limited home ranges.

Juvenile and young-adult fish can be found around estuaries mangroves and oyster bars. The typical spawning season is June through October; peak spawning within the Gulf of Mexico occurs from July through September.

5 There is still some debate whether this fish transitions from female to male as there appears to be a lack of conclusive evidence that this species is a protogynous hermaphrodite. Cryptic genetic divergence in a threatened marine fish and the resurrection of a geopolitical species.
