Groupers refer to the fish species under the family and genera Epinephelinae. Under Epinephelinae some common species are Atlantic goliath grouper (Epinephelus itajara), giant grouper (Epinephelus lanceolatus), and red grouper (Epinephelus morio).

Groupers are a type of ray-finned fish that can grow extremely large. These fishes have stout bodies with large mouths. They range from yellow-brown to gray in color with dark spots. The grouper fish are found in the regions of Florida, South America, Central America, and the Gulf of Mexico. Their habitat is in shallow temperate waters around the depths of 150 ft (46 m). They prefer areas of coral, rock, and mud bottoms in the ocean. They also inhabit mangroves and estuaries.

They are generally ambush predators. Their gills and mouth form a vacuum that pulls prey towards them. Groupers have the ability to change their color to match coral reefs to help camouflage themselves, especially the fish Caribbean Coney and Nassau grouper. Some fascinating Grouper facts are that they are monoandric protogynous hermaphrodites, which means they attain maturity only as females. They are one of the few species that have the ability to change their sex after reproduction maturity.

These species come together in specific locations to spawn for short periods of time in the Atlantic and Indo-Pacific regions.

The grouper season of spawning occurs in the months of July, August, and September. Groupers form aggregations of 100 or more individuals on rock ledges, coral reefs, etc. Once spawning is complete, females release eggs while males release sperm into the open offshore waters. Once the fertilization process is complete, the eggs hatch. Once they hatch the juveniles are about 1 in (2.5 cm) in length after 25 or 26 days.
