Cay

Definition of “Cay”

A “cay” is a small, low-lying island made of coral or sand that is typically found in warm, tropical waters such as those of the Caribbean Sea. The term is pronounced “key” and is commonly used in the region to refer to such landforms.

Cays are often formed over thousands of years, as sand and coral slowly accumulate on top of underwater reefs and other structures. Due to their delicate nature, cays can be particularly vulnerable to erosion and damage from storms and other natural events. Despite their small size, cays can be ecologically important as habitats for various plants and animals, including seabirds, turtles, and other marine life.

In addition to their role in supporting local ecosystems, some cays are popular tourist destinations, offering opportunities for swimming, snorkeling, and other water-based activities. The natural beauty and unique character of cays have also made them subjects of study for geologists, biologists, and other researchers interested in understanding the processes that shape island formation and the relationships between various forms of life in aquatic environments.
