is larger than the female by one third of his body size. Distribution The blue iguana is endemic to the island of Grand Cayman. As of 2012 the population can be found throughout the island Grand Cayman excluding the urban areas of Bodden Town, Gun Bay, Seven Mile Beach and West Bay. One theory for how the taxon ended up on the island is that a single female Cuban iguana, C. nubila nubila, with eggs inside her drifted across the sea, perhaps during a storm. Sometimes the Lesser Caymans iguana, C. nubila caymanensis, has been found on Grand Cayman. Ecology Habitat The blue iguana is found only on the island of Grand Cayman. Comparison with other Cyclura species in the region strongly suggests that there was once a coastal population of blue iguanas which was gradually displaced or extirpated by human settlements and the construction of roads. The blue iguana now only occurs inland in natural xerophytic shrubland and along the interfaces between farm clearings, roads, and gardens and closed-canopy dry forest or shrubland. The interior population is believed to have been attracted to agricultural clearings and fruit farms which provide thermoregulatory opportunities, herbaceous browse, fallen fruit, and nesting soil, but this brought the blue iguana into contact with humans and feral animals. Females often migrate to coastal areas to nest. Blue iguanas released into the Queen Elizabeth II Botanic Park on Grand Cayman were radiotracked in 2004 to determine ranges for each animal. Females were found to occupy territories of and males an average of with overlap in common territories, indicating that they choose to maintain a population density of four to five animals per hectare. The blue iguanas occupy rock holes and tree cavities, and as adults are primarily terrestrial. Although not known to be arboreal, it has been observed climbing trees and higher. Younger individuals tend to be more arboreal. Diet Like all Cyclura species, the blue iguana is primarily herbivorous, consuming leaves, stems, flowers, nuts, and fruits from over 45 species of plant. The diet is very rarely supplemented with insects, crabs, slugs and fungi. Blue iguanas have also been observed ingesting small rocks, soil, feces, and bits of shedding. Predators Hatchlings are preyed upon by the native snake Alsophis cantherigerus. The adults have no natural predators. Longevity Longevity in the wild is unknown but is presumed to be many decades.
