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 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. Jordan, 1923 Tribe Epinephrine Sleeker, 1874 Aethaloperca Fowler, 1904 Affected Bloch & Schneider, 1801 Anyperodon Gunther, 1859 Cephalopods Bloch & Schneider, 1801 Chromites Swanson, 1839 Dermatologist Gill, 1861 Epimetheus Bloch, 1793 Gonioplectrus Gill, 1862 Graciela Randall, 1964 Hyporthodus Gill, 1861 Mycteroperca Gill, 1862 Paranoia Guillemot, 1868 Plectropomus Pen, 1817 Scotia J.L.B.

Smith, 1964 Trio Randall, Johnson & Lowe, 1989 Various Swanson, 1839 The largest males often control harems containing three to 15 females.

Groupers often pair spawn, which enables large males to competitively exclude smaller males from reproducing. 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.

Wiki source has the text of the 1905 New International Encyclopedia article Grouper “. Reef groupers are eaten by larger fish like sharks, eels, and rays.

Giant grouper can grow to 8 feet, and they are eaten by sharks. The fins on the grouper are like needles, if you touch one, it injects a poison and feels like the sting of a bee.

Reef grouper are eaten by larger fish, such as sharks, eels, and rays. Giant grouper can grow up to eight feet and are eaten by sharks.

If you are referring to the fish known as grouper, a true vegetarian would say “No” and would not eat it. Fish is considered flesh or meat by vegetarians and therefore off limits.

Related Topics A grouper is any of a number of fish in the serranidae family and also includes sea bass. Some can grow to be as much as three and a half feet (about one meter) long and more than 200 pounds (a little under 100 kilograms) in weight.

Grouper usually swallow their prey, which include octopus, crab, fish, and lobster, whole. The fish also uses its large mouth to dig into the sand where it lies in wait for its prey.

Groupers are not fast, nimble swimmers, and they rely on sneak attacks to capture food. Cooks and fishermen might also encounter the colorfully named comet, saddle tail, or tiger grouper.
