The dorsal fin contains 7-8 spines and 10-12 soft rays while the anal fin contains 3 spines and 8 soft rays. This species has two color phases, one with black saddles on a whitish background color with a yellow caudal peduncle and yellow fins is known as the “footballer phase”; the other being a grayish form which has a dark head, five dark saddle markings along the back and small blue spots on body.
The juveniles are Bayesian mimics of the toxic Valentin's sharp nose puffer (Canthigaster Valentine). This species attains a total length of 125 centimeters (49 in), although they are commonly around 84 centimeters (33 in), and a maximum published weight of 24.2 kilograms (53 lb).
Plectropomus Levis is found in lagoon areas which have good coral cover and the seaward side of reefs where it appears to prefer reef channels and the outer shelf of the reef. The juveniles of both color phases with total length's of less than 20 centimeters (7.9 in) mimic Valentin's sharp nose puffer and usually scull with their pectoral fins for swimming while they hold the caudal fin folded and the first few spines of the spiny part of the dorsal fin held erect.
This species forages over larger areas and a wider depth range than the symmetric Plectropomus leopards. They are monastic protogynous hermaphrodites, in which the males only develop from mature females, the youngest males found have been 9 years of age and females mature at 2.2 years and at around 40 centimeters (16 in) in fork length.
This species is comparatively fast growing and may attain a length of 50 centimeters (20 in) in less than four years and females may be sexually mature in less than three years. They form small spawning aggregations although large aggregations have been recorded from the northern Great Barrier Reef.
It is likely that this species spawns in deeper waters on reef fronts compared to P. leopards and this may be the reason for the lack of spawning observations for P. Levis. The adults feed on a variety of larger reef fishes, including other groupers, while the juveniles feed on smaller fish and invertebrates such as crustaceans and squid.
Plectropomus Levis is a prized food fish but their diet dominated by fish means that the consumption of its flesh has been responsible for many instances of ciguatera poisoning. IUCN Red List of Threatened Species.

Its coloration is a white background with five large black saddles and one small one on the rear of the caudal area. There is a second color phase with a dark gray body with similar bars on it which is quite rare.
BlackSaddledCoralGrouper are found on the East coast of Africa from Durban in the south to the Red Sea, eastwards to northern Australia and up to southern Japan. They are typically found on exposed reefs rather than in protected areas or estuaries.
Their main diet is small fishes and crustaceans, however given they are regularly caught by fishermen on the hook this indicates that they will scavenge as well. They are ambush predators and usually feed in the early morning and late afternoon when their coloration gives them more camouflage.
Juveniles found over rubble areas in shallow reefs, colorful like a bright football, mimicking the poisonous Saddled Puffer fish. Groupers are solitary carnivores that hunt near the bottom usually at dusk.
Spawning is seasonal and controlled by the moons phase. Juvenile fish become adults and some change shape or their color.

Black grouper, scamp, snowy and yellow edge grouper are also available but are harvested in smaller volumes. They are found in warm temperate tropical waters around the coral reefs and rock outcroppings of the coastal shelf.
Groupers are harvested year-round with peak Eastern seaboard and Gulf production in summer and fall. Characteristics: The extra lean white meat is firm and moist with large flake and a sweet, mild flavor.

The Reef System begins at the Yucatán Peninsula’s northern tip and stretches south for nearly 700 miles through to the Honduran Bay Islands. The Belize barrier reef prides in being the country’s top tourist destination, famous for snorkeling and scuba diving.
The Mesoamerican barrier reef system features wetlands, mangroves, coral forms, seagrass, estuaries, and lagoons. The waters of the reef provide habitat to over 500 fish species ranging from lobster, snapper, tarpon, to grouper.
The whale shark is a naturally solitary animal, and it is the biggest known fish making its presence in the reef valuable. The mangroves serve as crucial nursery for fish while also acting as defense systems against strong storms and hurricanes.
Over the years, the Mesoamerican Barrier Reef has withstood natural disasters such as hurricanes and tropical storms, but it is currently threatened by human activities. The scenic beauty of the reef has created a prime tourist destination and fueled coastal development.
Pollution and sedimentation in the system have been attributed to human settlement and large-scale agriculture taking place inland. A research mission led by Florida Atlantic University's Harbor Branch Oceanographic Institute has uncovered details of one of Cuba's hidden natural treasures.
Except for a few places along the coast, prior to this expedition, there were virtually no data or charts indicating what was beyond the shallow reef zone. In addition to documenting these despotic reefs for the first time, important discoveries included numerous new species of sponges and range extensions or depth records for several species of corals, Oregonians, sponges, algae and fish.
They documented 123 species of fish, including numerous grouper and snapper on the despotic reefs. The invasive lionfish, which often number in the hundreds on despotic reefs off southwestern Florida, was present in relatively lower abundance at the study sites in Cuba.
“This expedition would not have been so successful without the hard work and collaboration of all the scientists from Cuba and the United States who participated in the cruise,” said John K. Reed, chief scientist and research professor at Far's Harbor Branch. “We were thrilled to discover that overall, the majority of the despotic reefs that we explored are very healthy and nearly pristine compared to many reefs found in the U.S. We saw little evidence of coral disease or coral bleaching, and evidence of human impact was limited to some lost long lines at some sites.
Using the University of Miami's Research Vessel F.G. Walton Smith as a platform for daily dives with the NOAA Marine Sanctuaries Foundation's Mohawk ROV, scientists from the U.S. and Cuba specializing in corals, sponges, algae and fish logged thousands of dive notes, underwater photos and video, documenting the geomorphology, biological donation and diversity of marine organisms. Many of the mission's ROV dives took place in or directly adjacent to Cuba's extensive network of marine protected areas (MPA's), providing an opportunity to explore locations for potential creation of new MPA's or expansion of existing boundaries.
During this expedition, the scientists identified at least four sites they believe should receive MPA status that are not currently protected. “This expedition was a very successful collaboration between numerous institutions, universities and scientists,” said Anton Post, Ph.D., executive director of Far's Harbor Branch.
