The Caribbean Sea is home to many kinds of fish, from snappers and groupers to parrotfishes, angelfishes and wrasses. Which species you find depends on the habitat: coral reefs, mangroves, lagoons, estuaries, hard bottoms and deeper reef areas support different communities. The examples below are representative, not a complete inventory of every fish in the sea.
Which fish are common on Caribbean reefs?
Coral reefs and other hard-bottom habitats support a wide range of fish. NOAA’s 2020 essential-habitat reference for the U.S. Caribbean—Puerto Rico and the U.S. Virgin Islands—lists managed reef-fish species from many groups. It is a regional management reference, not a complete list of all fish throughout the Caribbean Sea.
Snappers and groupers
Snappers include the yellowtail snapper (Ocyurus chrysurus). Groupers include the Nassau grouper (Epinephelus striatus), coney, graysby and red hind. Nassau grouper use different habitats and eat different prey as they grow, so a young fish and an adult do not necessarily occupy the same ecological niche. NOAA’s U.S. Caribbean essential-fish-habitat reference provides examples across these managed groups, while NOAA’s Nassau grouper profile describes the species’ changing habitat and diet.
Grunts and porkfish
Grunts include the French grunt (Haemulon flavolineatum), white grunt and bluestriped grunt. Porkfish (Anisotremus virginicus) is another reef-associated fish in this broader group of familiar examples.

Parrotfishes and other reef groups
Parrotfishes include the queen parrotfish (Scarus vetula), blue parrotfish (Scarus coeruleus) and stoplight parrotfish (Sparisoma viride). Caribbean reef-fish references also include goatfishes, squirrelfishes, jacks, basslets, boxfishes, angelfishes, surgeonfishes, gobies, blennies, wrasses, damselfishes, cardinalfishes, hawkfishes and triggerfishes. Those are broad groups, not a promise that every species occurs at every reef.
What fish live beyond coral reefs?
“Reef fish” describes only part of the region’s fish community. NOAA describes reef fish broadly as species associated with coral reefs, artificial structures and other hard-bottom areas; tilefishes are also associated with muddy bottoms and continental-shelf areas. Estuaries, lagoons, brackish waters and offshore environments support different fish assemblages. A list built from reef surveys therefore cannot describe every fish living in the sea. See NOAA’s overview of Atlantic, Gulf of Mexico and Caribbean reef fisheries and its historical Caribbean-area fish leaflet for habitat context.

Are Caribbean reef fish found only in shallow water?
No. A NOAA project page published July 21, 2017, says many reef-fish species captured by commercial and recreational fishers in the U.S. Caribbean use reef habitat deeper than 35 meters. That finding applies to fishery-captured reef-fish species in Puerto Rico and the U.S. Virgin Islands; it is not a depth limit for all Caribbean fish. NOAA’s National Coral Reef Monitoring Program evaluates fish diversity, distribution, abundance and size through shallow-water surveys in the Atlantic, Caribbean and Gulf region on a two-year cycle, so those surveys are useful for monitoring but are not an exhaustive inventory of deep or non-reef habitats. NOAA’s 2017 survey project and its biological monitoring overview describe those scopes.
How many fish species live in the Caribbean Sea?
A single fish-only total is not established by the figures cited here. NOAA’s Caribbean regional status page reports 1,400 species of fish and marine mammals combined; that number must not be read as 1,400 fish species. Separately, a 2017 NOAA project page says more than 50 reef-fish species are captured by commercial and recreational fishers in the U.S. Caribbean. That is a count of fishery-captured species in a particular geographic and fishery context, not a census of all fish living in the Caribbean Sea. NOAA’s Caribbean Region status page gives the combined figure.

Why do Caribbean fish names vary?
Common names can differ from one island or community to another, and the same common name may be used for more than one species. NOAA’s historical Caribbean-area leaflet explicitly warns that names vary and that its list is incomplete and may not be accurate in every detail. When identification matters, pair the local common name with a scientific name and check a current, location-specific reference rather than treating a broad regional list as definitive.
