There are approximately 150 different kinds of groupers in the world. Thirty-seven species are known to spawn in the Caribbean including the waters throughout the Bay Islands.
Most grouper species are coastal demersal fish, which means they usually live and eat near the sea floor. They are not designed for long and fast swimming. Some groupers can be quite large, and measure over a meter. The huge Goliath grouper can grow up to 8.2 feet (2.5 m). Others, like the Graysby, can be as small as 7 in (17 cm).
All varietals of groupers are opportunistic predators, they eat a wide variety of foods. While they prefer to eat fish, they often eat crustaceans and invertebrates like octopus and squid. Since they don’t have many teeth, they swallow prey rather than biting them. They use their big wide mouths and powerful gill muscles to create a strong suction that can suck the designed victim even from a distance. Some species prefer to ambush their prey, while other species are active predators.
Groupers are mostly monandric protogynous hermaphrodites. They are born and mature as females but they have the ability to change their sex for reproduction purposes. Black groupers are very easy to spot while others, like the Goliath grouper are more difficult to find.

Nassau is probably the most well know grouper, thanks to its unique pattern and body color. It is known to change from tawny, for the ones living in shallow water, to pinkish, red, or sometimes orange-red for specimens living in deeper waters. Nassau grouper has been overfished for years and is listed as threatened under the Endangered Species Act.
Nassau Groupers can live up to 29 years. They can be found offshore on rocky reefs and drop offs. Juveniles can most commonly be seen in shallow water on the nearshore reefs.
• MAX SIZE: 3,5 ft (100 cm) • MAX WEIGH: 55 lbs (25 kg) • DEPTH RANGE: 20 – 426 ft (6 – 130mt)

When threatened it shows aggressive body language and a rumbling sound produced from its swim bladder.
Rare to be seen, they live around rocky coral and muddy inshore habitats. They eat everything in sight; crustaceans, fish, stingray, young sea turtles and even small sharks. They can live up to 50 years.

Is grouper a good fish to eat?
What is the best grouper to eat?
What kind of grouper are in the Bahamas?
Do people eat the Nassau grouper?
What does grouper taste like?
Grouper is a saltwater fish commonly found around the Gulf of Mexico and the Caribbean. The taste of fish varies depending on its habitat. Some are mild tasting, whereas others can have a more flavorful kick. The most common way to cook grouper is by frying or grilling it.
Where do Nassau groupers come from?
Sampling of fish landed in the U.S. Virgin Islands and Puerto Rico during the 1970s and 1980s indicates that Nassau grouper were commonly caught, mostly from spawning aggregation sites. Currently, Nassau grouper are occasionally reported during underwater reef surveys at low density.
How do I choose a good grouper fish?
When choosing your grouper, look for firm and moist flesh, and avoid fish with a strong fishy odor or an overly white color. Avoid overcooking the fish, as it can become quite rubbery and dry. Once it starts to flake, the fish is ready to serve. If pan-grilling the fish, always use a non-stick pan or skillet.
Is a Nassau grouper a reef fish?
The Nassau grouper is considered a reef fish, but it transitions as it grows through a series of shifts in both habitat and diet. As larvae they are planktonic. As juveniles they are found in nearshore shallow waters in macroalgal and seagrass habitats. They shift deeper as they grow, to predominantly reef habitat (forereef and reef crest).
