Cyclura carinata
The species is found on 50–60 of the > 200 islands comprising the Turks and Caicos island banks. The combined surface area of all islands in the Turks and Caicos is approximately 500 km². The extent of occurrence for iguanas is 13 km², most of which is accounted for by three large cays (Big Ambergis, Little Ambergris and East Bay). In the Bahamas, the species is found only on Booby Cay, located 0.5 km off the eastern end of Mayaguana Island. The cay is 2 km in length and varies from 100–750 m wide. Approximately 30% of the cay is taken up by two ponds.
The Turks and Caicos rock iguana inhabits small cays, but has been reduced to less than 5% of its original range largely due to the introduction of predators. The Turks and Caicos rock iguana dwells in rocky areas and sandy habitats as sand is required for nesting. The Turks and Caicos iguana is diurnal and spends the night in the burrows it has dug or in natural retreats in or under the rocks.
