Iguana GuideIdentification
Green iguanas have long tails, a row of dorsal spines and a prominent dewlap. Despite the common name, adults do not always appear bright green; age, sex, temperature and context can influence visible coloration.
Range and habitat
UF/IFAS describes the native range as extending from central Mexico south to Paraguay and Brazil, with native populations on some Caribbean islands. They occupy tropical rainforest, dry forest and savanna, often near permanent water.
Daily life
Green iguanas are strong climbers and swimmers. They bask to regulate body temperature, forage largely on plant material, and may dive into water when startled. At night they use trees and other sheltered sites.
Communication
Visual signaling is important. Posture, dewlap extension, head movements and body orientation can convey information during territorial, social and reproductive interactions.
Keep exploring
Iguana facts become more useful when anatomy, behavior, species and habitat are connected instead of treated as isolated trivia.
