What is cays?

Cays are small sandy islands that are formed on the surface of coral reefs. They are common in tropical regions, particularly in the Caribbean Sea and the Western Atlantic Ocean. Cays are typically low-lying and may be only a few meters above sea level. They are often surrounded by shallow, clear water and are popular spots for recreational activities such as snorkeling and diving.

Cays are characterized by their sandy beaches and the vegetation that grows on them. The vegetation is typically low-lying and adapted to the harsh coastal environment. It may include grasses, shrubs, and small trees. Animal life on cays is often diverse and may include seabirds, reptiles, and marine creatures such as turtles and rays.

Cays are interesting geological formations because they are formed solely by the accumulation of sediment on top of coral reefs. They are highly vulnerable to erosion, storm surge, and sea level rise, which makes them important indicators of climate change and ocean health. Efforts to protect and preserve cays are therefore important for the maintenance of a healthy marine ecosystem, as well as for the enjoyment of visitors to these unique islands.
