Green Iguana or the American Iguana is herbivorous, large arboreal lizard species and is related to genus Iguana. Usually, the animal is simply called as Iguana and is found on the islands as well as rain forests of Central America, Caribbean, and South America. Green Iguanas are considered to be invasive species. They are not only the largest lizards in the American continent but are also very popular reptile pets because of their calm nature and bright color. Despite the fact, it is tough to take care of these animals purely because of their diet. Due to this, most of the iguanas die within the first year when kept as pets and a major portion of the owners give them to the animal rescue services.
