An iguana sunning itself on the island of Sint Maarten

A iguana is a species of herbivorous lizard that is native to tropical regions of Mexico, Central America, several islands in Polynesia such as Fiji and Tonga, as well as the Caribbean. The Lesser Antillean iguana is native to the Lesser Antilles, a region where habitat destruction has resulted in the extinction of the green iguana, which is widespread throughout its range and popular as a pet.
