Range Description

The Sister Isles Rock Iguana is native to two islands: Cayman Brac (38 km) and Little Cayman (28.5 km). The islands are 7.5 km apart and are well isolated from other land masses in the area. Both islands have been continuously inhabited by people since the early 1800s. Current human population sizes for Cayman Brac and Little Cayman are approximately 2,000 and 150 respectively. It occurs from sea level up to 45 m.

On Little Cayman, the iguana is distributed throughout the island, although the actual area of occupancy is only 18 km due to many mangroves and forests dissecting suitable habitats. Once equally widespread on Cayman Brac, the very few iguanas remaining seem restricted to areas in the west, south coast, and centre of the island, and occupy an area of about 20 km.
