Grand Cayman Island Rock Iguana

Cyclura nubila lewisi

Status in the Wild: Endangered

The Grand Cayman Island Rock Iguana is one of the rarest lizards in the world. Today, only two viable populations of this lizard remain on Grand Cayman.

Range: They survive in only a three square mile area of eastern Grand Cayman.

Habitat: The rock iguana usually occupies dry evergreen thickets and bush land. They often travel to new habitats in search of food and nesting areas, as well as to avoid predators and human interference.

This large lizard can measure as much as four feet in length and weigh 15 to 20 pounds. The average life span is about 50 years. Rock iguanas are normally blue-gray in color when resting. During breeding season or when excited, they turn turquoise blue over half their body and are referred to as the "blue iguana." Primarily herbivores, they prefer vegetation and have been known to consume at least 45 different plant species. Occasionally, rock iguanas enjoy some fruits.
