Yup, they are a green iguana, from a different side of the world is all. I have a female red iguana, shes no bigger then any green iguana her age, shes also VERY inteligent, one of the most inteligent iguanas I have ever seen, but it probably has nothing to do with being a red iguana. I have only had her 3 months now, and she will literally come to her cage door and climb right ontop of us to let us know she wants food and she wants it now.
