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. 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. IUCN Red List of Threatened Species.

Wikimedia Commons has media related to Epimetheus Tamara. I learned about it from a buddy diver who excitedly told me to go diving with him upon a prompt from a classmate in high school who happened to be the mayor of that town.
Probably, I am lucky that the Goliath grouper (Epimetheus quinquefasciatus) I encountered several minutes when I plunged into the water was still a juvenile. I brought with me my automatic Nikon camera encased in a plastic casing to make it water-resistant as taking pictures is a pleasure for me each time I travel.
I grabbed the camera hanging by a tough nylon string around my wrist, and took a video of the Goliath grouper following my buddy. Despite the huge size of the Goliath grouper, they seem to be docile fishes although there are reports that they do attack humans.
I saw one video that says so but analyzing the situation, I thought the reason was mainly to feed, not really to attack. The moving fins attracted the grouper thinking probably that it was its prey and snapped on it.
When the juveniles are older, they migrate to the coral reefs and stay there for more than 40 years. When they are old enough to reproduce, the Goliath groupers migrate and spawn into the deeper water column, fertilize the eggs which then are carried by the current, hatch then drift in the currents for 30 to 80 days (Fig.

The giant of the grouper family, the Goliath (formerly called Jewish) has brown or yellow mottling with small black spots on the head and fins, a large mouth with jawbones that extend well past its small eyes, and a rounded tail. The skeletal structure of large Goliath grouper cannot adequately support their weight out of the water without some type of damage.
If a large Goliath is brought on-board a vessel or out of the water, it is likely to sustain some form of internal injury and therefore be considered harvested. Goliath grouper populations declined throughout their range during the 1970s and 1980s due to increased fishing pressure from commercial and recreational fishers and divers.
At their July 2014 meeting in Key Largo, this committee reviewed the most up-to-date scientific information on goliathgrouper and recommended a new stock assessment for this species. As a result, the most recent stock assessment, conducted by the FCC was completed in June 2016 (Sedan 47).
The stock assessment indicates abundance in south Florida has greatly increased since the fishery closed in 1990. However, in the final step of the review process, the assessment was rejected by an independent panel of scientists for use in federal management due to a lack of reliable indicators of abundance outside south Florida.
Goliath are also susceptible to large scale mortality events such as cold temperatures and red tide blooms. When not feeding or spawning, adult Goliath groupers are generally solitary, sedentary and territorial.
Before the goliathgrouper reaches full-size it is preyed upon by barracuda, king mackerel and moray eels, as well as sandbar and hammerhead sharks. Calico crabs make up the majority of their diet, with other invertebrate species and fish filling in the rest.
Reproductive maturity first occurs in fish 5 or 6 years of age (about 36 inches in length) due to their slow growth rate. Males mature at a smaller size (about 42 inches) and slightly younger age than females.
These groups occur at consistent sites such as wrecks, rock ledges and isolated patch reefs during July, August and September. Studies have shown fish may move up to 62 miles (100 km) from inshore reefs to these spawning sites.
In southwest Florida, presumed courtship behavior has been observed during the full moons in August and September. Epimetheus Tamara may be a widespread, slow growing, and aggregating species that has undergone vital population reduction over the past three generations (40.5 years) calculable to be a minimum of 80th based on landings information and underwater visual censuses.
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. It’s territorial close to areas of refuge like caves, wrecks, and ledges, displaying an open mouth and quivering body to intruders.
These teams occur at consistent sites like wrecks, rock ledges and isolated patch reefs during July, August and September. Studies have shown fish could move up to 62 miles (100 km) from inshore reefs to these spawning sites.
In southwest Florida, plausible entreaty behavior has been observed during the complete moons in August and September. Occurring in shallow, inshore waters to depths of 150 feet (46 m), the Epimetheus Tamara prefers areas of rock, coral, and mud bottoms.
It’s a classic apex predator, large, rare and solely some people occur on any given reef unit. As with other fish, the Atlantic goliathgrouper is the host of several species of parasites, including the diplectanid monogenean Pseudorhabdosynochus Americans on its gills.
Calico crabs frame the bulk of their diet, with alternative invertebrate species and fish filling within the rest. Goliath grouper feed mostly on crustaceans (in particular spiny lobsters, shrimps and crabs), fishes (including stingrays and parrot fishes), octopus, and young ocean turtles.
