Green Iguana

My animal is a green Iguana. I think it eats flies, grasshoppers and small snakes.My animal lives in the southern american rainforests.It can look green brown or grayish green. This is my animal 1000 years from now. It would live in the desert and it would look brown, yellow and grey.Now it would eat scorpions, wasps and small snakes.It would live in the sahara desert.Thats what my animal would eat look and camouflage.
