The green iguana is one of the iconic species of the neotropical rainforest. This species has an extensive range stretching from Northern Central America southward throughout the Amazon Basin. They’ve also been introduced in South Florida, as well as the lower Rio Grande area of South Texas. Green iguanas are the largest lizard in the Amazon Basin, including the Peruvian Amazon, and large males may reach six feet in length. Females are considerably smaller, reaching about four feet in length.
