An ISLET is a small, typically uninhabited piece of land located in the ocean. It is usually surrounded by coral reefs or other bodies of water and is often referred to as a tiny spot of land in the ocean. Islets are usually very small, with an area of less than one hectare, and can be found in many parts of the world. They are often used as nesting sites for seabirds and other marine life, and can provide a refuge for endangered species.
