What are Coral Reefs and How were Grand Cayman’s Formed?

The seeds of coral reef formation are free-floating coral larvae. These organisms attach themselves to submerged rocks (or other hard surfaces, such as shipwrecks) around the edges of islands and land masses. Over time, the coral formation grows, developing into either a barrier reef, fringing reef, or atoll.

Corals are colonies consisting of hundreds, if not thousands, of tiny animals known as polyps. Related to sea anemones and jellyfish, polyps use calcium carbonate from the seawater to create a tough external skeleton. These skeletons can grow into enormous structures that, as a collective, provide the limestone framework for a tropical coral reef.

The Cayman Islands are unique geological formations, part of the peaks of an underwater mountain range known as the Cayman Ridge. The deepest part of the Caribbean Sea (around 25,216 feet/7,686 meters below sea level) lies to the south of our islands. The low-lying limestone platforms and narrow island shelves around Grand Cayman are perfect for supporting coral reefs.

How to Behave When Exploring Coral Reefs in Grand Cayman

To ensure the preservation of Grand Cayman’s coral reefs, it’s crucial to follow responsible and sustainable practices when visiting the best places to snorkel and the best scuba diving sites in the Cayman Islands

Red Sail Sports encourages all explorers to:

  • Refrain from touching or standing on the coral: Even the lightest touch can harm these delicate ecosystems.
  • Use reef-safe sunscreen: Chemicals in traditional sunscreens can be harmful to coral. Opt for reef-safe alternatives.
  • Maintain a safe distance from marine life: Admire from afar and avoid disturbing the natural behaviour of the creatures you encounter.
  • Do not feed the fish: It disrupts their natural feeding habits and can lead to dependency on human food.
