Green Iguanas are arboreal lizards that live high in the tree canopy in tropical rain forests and generally near a water source. The scales or plates on the head are larger and more irregular than the scales on the rest of the body. The color of an individual may also vary based upon its mood, temperature, health, or social status. When frightened, an iguana will usually freeze or hide. If caught, twisting, and rotating around or tail whipping may occur. They can also detach their tails if caught and will grow another without permanent damage. They prefer to bask in trees, near water areas, so when threatened by a predator they can dive into the water and swim swiftly away. No matter where they inhabit, they prefer to have water around. No matter where they inhabit, they prefer to have water around. They are ectothermic. Their body temperature is mainly dependent upon the environmental temperature.



Animals are getting endangered day by day due to manmade disasters. Even though green iguanas have classified as the least concern under IUCN some populations in different areas are vulnerable and endangered. Green iguana in Belize is a high threat due to hunting for flesh meat and eggs. Green Iguana Conservation Project is focusing on protecting the species as well as educating the community on the natural history and their release program.
