They’re a reptile that has been very successful in tropical regions of the Americas and thanks mostly to the pet trade they have extended their range into the United States.
Iguanas are native to tropical areas of Mexico, Central America, South America, and the Caribbean, with some species also found in the Pacific Islands (the Galapagos have a unique marine iguana), and they have even expanded to places like Florida and Hawaii as introduced species mostly from the pet trade. You’ll find them in a range of sizes from a few inches to several feet ling with colors from bright green to grey and black. Still the range is limited as they cannot survive freezing temperatures.
