The dorsal profile of the head and the intraorbital area are convex, The properly has a rounded corner and a finely serrated margin. The gill cover has a convex upper margin.

The adults are greyish-brown in color overlain with a mottled pattern and with darker fins. The giant grouper can grow to huge size with the maximum recorded standard length being 270 centimeters (110 in), although they are more common around 180 centimeters (71 in).

And a maximum published weight of 400 kilograms (880 lb). The giant grouper is a species of shallow water and can be found at depths of 1 to 100 meters (3.3 to 328.1 ft).

Large specimens have been caught from shore and in harbors. They are found in caves and in wrecks while the secretive juveniles occur in reefs and are infrequently observed.

The adults are mainly solitary and hold territories on the outer reef and in lagoons. They have also been caught in turbid water over silt or mud sea beds by prawn fishermen.

The giant grouper is an opportunistic ambush predator which feeds on a variety of fishes, as well as small sharks, juvenile sea turtles, crustaceans and mollusks which are all swallowed whole. Fish which inhabit coral reefs and rocky areas favor spiny lobsters as prey and 177 centimeters (70 in) specimen taken of Maui in Hawaii had a stomach contents of two spiny lobsters and a number of crabs.

Fish living in estuaries environments in South Africa were found to be feeding almost exclusively on the crab Scylla errata. They are, however, curious and frequently approach divers closely.

They are not generally considered dangerous to humans but divers are advised to treat large specimens with caution and not to hand feed them. They are aggregate broadcast spawners, usually with several females per male.

Studies in captive populations suggest that the dominant male and female begin the spawning event as nearly the only spawners for the first day or two, but other members of the aggregation fertilize more eggs as the event progresses, with even the most recently turned males fathering offspring. Giant groupers are diabetic protogynous hermaphrodites, meaning that although some males develop from reproductively functional females other males start to produce sperm without ever having gone through a phase as a reproductive female.

The giant grouper is a highly valued food fish and is taken by both commercial and recreational fisheries. As well as the consumption of its flesh its skin, gall bladder and stomach are used in Traditional Chinese Medicine.

It is valued in Hong Kong as a live fish for the live reef food fish trade, especially smaller specimens. This species is cultured in agriculture and this practice is widespread but there is a restricted supply of juveniles, although hatcheries in Taiwan have produced captive bred juveniles, exporting some for to be grown on in other parts of South-East Asia.

Many of the fish produced in aquaculture are hybrids between this species and E. fuscoguttatus. IUCN Red List of Threatened Species.

Grouper Malabar grouper, Epimetheus malarious Scientific classification Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Performed Family: Serranidae Subfamily: EpinephelinaeBleeker, 1874 Tribes and genera Not all errands are called 'groupers'; the family also includes the sea basses. The common name grouper is usually given to fish in one of two large genera : Epimetheus and Mycteroperca.

In addition, the species classified in the small genera Hyperion, Completes, Dermatologist, Graciela, Scotia, and Trio are also called 'groupers'. However, some hamlets (genus Affected), the hinds (genus Cephalopods), the lyre tails (genus Various) and some other small genera (Gonioplectrus, Nippon, Paranoia) are also in this subfamily, and occasional species in other serrated genera have common names involving the word grouper “.

Nonetheless, the word grouper on its own is usually taken as meaning the subfamily Epinephrine. Groupers are Telecasts, typically having a stout body and a large mouth.

They can be quite large, and lengths over a meter and the largest is the Atlantic Goliath grouper (Epimetheus Tamara) which has been weighed at 399 kilograms (880 pounds) and a length of 2.43 m (7 ft 11 1 2 in), though in such a large group, species vary considerably. They do not have many teeth on the edges of their jaws, but they have heavy crushing tooth plates inside the pharynx.

They habitually eat fish, octopuses, and crustaceans. Reports of fatal attacks on humans by the largest species, such as the giant grouper (Epimetheus lanceolatus) are unconfirmed.

They also use their mouths to dig into sand to form their shelters under big rocks, jetting it out through their gills. The word grouper is from the Portuguese name, group, which has been speculated to come from an indigenous South American language.

In Australia, “groper” is used instead of grouper for several species, such as the Queensland grouper (Epimetheus lanceolatus). In New Zealand, “groper” refers to a type of wreck fish, Poly prion oxygenate, which goes by the Mori name haiku.

In the Middle East, the fish is known as hammer ', and is widely eaten, especially in the Persian Gulf region. The species in the tribes Grammistini and Diploprionini secrete a mucus like toxin in their skin called Rammstein and when they are confined in a restricted space and subjected to stress the mucus produces a foam which is toxic to nearby fish, these fishes are often called soap fishes.

The largest males often control harems containing three to 15 females. As such, if a small female grouper were to change sex before it could control a harem as a male, its fitness would decrease.

If no male is available, the largest female that can increase fitness by changing sex will do so. Gonochorism, or a reproductive strategy with two distinct sexes, has evolved independently in groupers at least five times.

The evolution of gonochorism is linked to group spawning high amounts of habitat cover. Both group spawning and habitat cover increase the likelihood of a smaller male to reproduce in the presence of large males.

Fitness of male groupers in environments where competitive exclusion of smaller males is not possible is correlated with sperm production and thus testicle size. Gonochoristic groupers have larger testes than protogynous groupers (10% of body mass compared to 1% of body mass), indicating the evolution of gonochorism increased male grouper fitness in environments where large males were unable to competitively exclude small males from reproducing.

Many groupers are important food fish, and some of them are now farmed. Unlike most other fish species which are chilled or frozen, groupers are usually sold live in markets.

Groupers are commonly reported as a source of Ciguatera fish poisoning. DNA barcoding of grouper species might help in controlling Ciguatera fish poisoning since fish are easily identified, even from meal remnants, with molecular tools.

In September 2010, a Costa Rican newspaper reported a 2.3 m (7 ft 7 in) grouper in Cieneguita, Limón. The weight of the fish was 250 kg (550 lb) and it was lured using one kilogram of bait.

In November 2013, a 310 kg (680 lb) grouper had been caught and sold to a hotel in Dong yuan, China. ^ a b c d e Richard van der Loan; William N. Scholar & Ronald Cricket (2014).

The dorsal profile of the head is flat to slightly convex between the eyes. It has a rounded, finely serrated properly which has a fleshy lower edge.

The membranes of the dorsal fin has distinct indentations between its spines. The dorsal fin has 9 spines and 14-15 soft rays while the anal fin has 3 spines and 8-9 soft rays.

The color of the body is orange-red to reddish brown with many small bright blue spots which cover the head, body and the dorsal, anal and caudal fins. The color of the juveniles is orange to yellow with fewer widely separated faint blue spots.

They attain a maximum total length of 50 centimeters (20 in). Cephalopods minima is found in clear water where there are coastal and offshore coral reefs, it prefers exposed rather than protected areas.

Like other groupers this species is predatory; over 80% of its diet consists of small fish, predominantly sea oldies (Pseudanthias squamipinnis) which are ambushed by the coral hind in a sudden rush up from the substrate. They form harems consisting of a single male and up to 12 females.

The male defends the harem's territory which is around 475 square meters (5,110 sq ft) in area, each female has a smaller territory which she defends against other females. Coral hinds are protogynous hermaphrodite, and they change sex from female to male.

The male patrols the territory and visits each female, swimming parallel to each other when they meet. Cephalopods minima is an important species in commercial fisheries at the local level and is caught using hook and line, fish traps and spears.

It is a colorful species and is popular in public Aquarian and forms a minor part of the aquarium trade. IUCN Red List of Threatened Species.

They even eat other large fish and small Sharks, but they’re favorite food is Crayfish. You can find this species throughout the Indo-Pacific region (excluding the Persian Gulf), from South Africa to the Hawaiian Islands.

Anglers and scientists have recorded Queensland Groper in Malaysia, Indonesia, the Philippines, Japan, and China. Juvenile Queensland Gropers inhabit estuary systems and shallow inshore reefs.

All Goliath Groupers are born female, and can naturally choose to change their gender later in their life. They are bottom dwelling fish that get their food from particles that drift down.

Although they are Saltwater Fish by nature, Jeremy caught both a Giant and a Goliath Grouper in River mouths. The Goliath Grouper only appeared once in Season 4, when Jeremy caught one on accident in Florida while fishing for a Bull Shark.

The Atlantic Goliath grouper or Tamara (Epimetheus Tamara), also known as the Jewish, is a large saltwater fish of the grouper family found primarily in shallow tropical waters among coral and artificial reefs at depths from 5 to 50 m (16 to 164 ft). 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 Goliath grouper 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 Goliath grouper 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 Goliath grouper 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.
