Green iguanas are very strong creatures. Their tail is sharp so they can whip it at other predators. They are herbivores and they eat plants, leaves, fruits, and flowers. They live in rain forests like in Mexico, Texas, and Florida. There is extra skin under a green iguana’s neck that is used to regulate their temperature. In the future, because of global warming, the North and South poles are melting. Our oceans are rising and the temperature is going up. I think green iguanas would change and live in the water. They would grow gills and webbed feet and hands. Their tail would grow a fin to help them swim better. They would eat all types of underwater plants. The reason I think green iguanas should live underwater is because they are cold blooded and they cannot withstand extremely hot temperatures and the green iguana will not survive.
