Green Iguana Habitat

Common Iguanas (Iguana iguana), also known as Green Iguanas, have escaped from the domestic pet trade on Grand Cayman, and are breeding in the wild throughout the western districts of the island. They are native to Central and South America, where they evolved in the presence of many predators. Common Iguanas therefore have instinctive strategies to avoid being eaten by cats and dogs, and they are thriving in suburban areas where Blue Iguanas would not stand a chance.

Common Iguanas are now numerous and sighted often, while the critically endangered Blues are almost never seen outside protected areas. More and more, people are beginning to mistakenly assume the Common Iguana actually IS the Cayman’s own Blue Iguana!

The two species are very different, and can not breed together. They don’t even speak the same “language” – when a Blue Iguana threatens a Common Iguana by head-bobbing, the Common Iguana does not understand. Size for size, the Blue Iguana is much stronger and much more aggressive.
