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.

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.

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. This skilled ambush hunter can be found in shallow reef environments in the western Atlantic and eastern Pacific, where it feeds on crustaceans, rays, fish and even turtles.

This grouper is known to exhibit territorial behavior near its preferred spot on a reef or wreck, and may threaten intruders by shaking its body, opening its mouth wide or even using its swim bladder to make a loud booming noise 8 feet (240 cm) Crustaceans, especially spiny lobsters, as well as turtles, fish and stingrays Atlantic Ocean and eastern Pacific Ocean Shallow water The Goliath grouper reaches a length of 8 feet (240 cm) and the largest published weight is 1003 lbs.

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. This fish typically remains in shallow water, although a few individuals have been reported at depths of 280 feet (85 m).

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.
