Cyclura lewisi, known as the Grand Cayman Blue Iguana, is a large lizard endemic to Grand Cayman. It is renowned for its striking blue coloration, especially during the breeding season. These iguanas inhabit rocky, sunlit areas and are primarily herbivorous, playing a crucial role in seed dispersal within their ecosystem.

Cyclura lewisi, commonly known as the Grand Cayman blue iguana, is native to Grand Cayman, the largest of the Cayman Islands, located in the Caribbean Sea.

The Grand Cayman blue iguana primarily inhabits dry, rocky forests and shrublands characterized by open, sunny areas that are crucial for basking. The region experiences a tropical climate with a distinct dry season and a wet season, with temperatures typically ranging from 24°C to 30°C (75°F to 86°F).

As a terrestrial herbivore, Cyclura lewisi plays a vital role in its ecosystem by aiding in seed dispersal through its diet, which consists mainly of leaves, flowers, and fruits. The species is adapted to the karst landscape of Grand Cayman, which provides ample crevices and shelters for protection against predators and extreme weather conditions.
