The red grouper, scientific name Epinephelus morio is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is a part of the family Serranidae, which additionally consists of the anthias and sea basses. It is discovered within the western Atlantic Ocean.
Red Grouper Overview
Red grouper is present within the Western Atlantic from the Carolinas south to Brazil, together with the Gulf of Mexico, Caribbean, and Bermuda; nevertheless.
It’s most ample within the eastern Gulf of Mexico. There have been experiences of red grouper often seen as far north as Massachusetts.
In basic, red grouper is a darkish brown color with a reddish hue on its back and sides, fading to a pale pink beneath.

It is a bottom-dwelling fish; throughout spawning season, males are territorial and considerably sedentary, excavating holes as house territories.
The spawning season happens anyplace from January to early June relying on the world. Generally, peak spawning happens from March to May.
As with different species within the grouper family, red grouper is a protogynous hermaphrodite, with all starting life as females, and with most females transitioning to males between the ages of seven to 14.6.
Red grouper is out there year-round with peak catches within the Atlantic and Gulf of Mexico occurring in the course of the summer season and fall. Approximately 70% of the grouper harvested in U.S. waters is red grouper.
Groupers are typically offered as “sea bass,” “mero” or the Hawaiian name “hapu’u”. The fish is offered contemporary and frozen as complete fish, fillets, and steaks.

The Red Grouper isn’t a migratory fish and might usually be discovered close to our eastern seaboard—from as far north as Massachusetts right down to Florida and into the Gulf of Mexico. It may also be discovered overseas as far south because of the Caribbean Sea as much as southern Brazil.
This fish primarily prefers muddy and rocky backside underwater habitats at depths of 16 to 1,083 feet. It may also be seen swimming or resting shut inshore, particularly in reefs, ledges, and wrecks of as much as 300 deep, with many anglers catching these tasty fish in about 10 to 100 feet.
As the name suggests, the Red Grouper (Epinephelus morio) can simply be distinguished from different groupers by the principally rusty red coloration of its body.
While its head and higher elements are typically darker, the color progressively lightens till it reaches the reasonably light red to pinkish hue of the stomach.
It additionally has some type of blotches on its aspect and a few distinctive white spots on its body—from the pinnacle right throughout to the bottom of its tail.
And though the fins typically have the same coloration as its body, they often have some type of a black margin that runs right across the edges.
The body of the Red Grouper is understood to be strong and meaty although it’s principally average in size. It has a big mouth which permits them to eat its prey whole.
Its lower jaw protrudes slightly bit past the higher jaw, each of that is outfitted with a number of units of razor-sharp teeth that the fish makes use of to forestall its prey from escaping, to not rip its flesh aside. Its prey principally consists of marine invertebrates together with octopi, shrimps, and crabs, however now and again may even eat smaller fishes.
The Red Grouper is a protogynous hermaphrodite fish. This signifies that all of them are females at the very starting of their life. Many would, nevertheless, change to males as quickly as they hit their sexual maturity, which is between seven and fourteen years of age.
When the spawning season comes which often happens between January and April, each the males and the females would launch their sperms and eggs within the water.
The fertilized eggs would simply drift with the currents till they hatch into larvae in about thirty hours. The larvae would simply then live among the many zooplanktons close to the floor of the water.
As they attain their juvenile stage, they might swim right down to the underside of the water and settle inside seagrass beds the place they might prey on smaller fishers and completely different marine invertebrates till they attain their full maturity.
Distribution
The red grouper’s typical range is coastal areas within the western Atlantic, stretching from southern Brazil to North Carolina within the US and together with the Gulf of Mexico and Bermuda.
Red Grouper Description

Usually solitary till spawning time, it grows to 4 feet (1.2 meters) in size and resides alongside rocky or muddy bottoms in heat waters (frequent to fifteen pounds). *Florida Record: 39 lbs., 8 ozs.
Red Grouper Habitat
The red grouper is a demersal, largely sedentary species that has an extended (~40 days) pelagic larval stage before it settles in shallow coastal hardbottom habitat as juveniles.
They stay in inshore waters for 4–5 years before migrating to offshore hardbottom habitat—significantly on the sting of the continental shelf—as adults.
Spawning happens offshore between January and June, peaking in May. While primarily consuming benthic invertebrates, the red grouper is an opportunistic feeder within the reef community.
The diet generally consists of xanthid and portunid crabs, juvenile spiny lobster, and snapping shrimp, with the occasional fish. The red grouper is of average size, about 125 cm, and weighs 23 kg or more.

They use their caudal fin and their mouths to take away particles and sediment from rocks, creating uncovered surfaces on which sessile organisms actively settle (e.g., sponges, smooth corals, algae).
The publicity of construction additionally attracts a myriad of different species, together with mobile invertebrates and an exceptional variety of different fishes, from gobies and butterflyfish to grunts and snappers.
The lionfish Pterois volitans began invading red grouper habitat by 2008, from Florida Bay to the Florida Keys and offshore to Pulley Ridge, a mesophotic coral reef on the West Florida Shelf west of the Dry Tortugas.
Known for being extraordinarily successful predators on small reef fish, scientists are very focused on figuring out the extent to which their invasion modifications the purposeful dynamics of related communities.
