Iguana

In the future I think that the iguana will be different. Because iguanas need about 70% humidity and their adaptation is that they have very strong jaws,razor sharp teeth. If the humidity goes down I think the iguana will look different. I think that their tails will be shorter because if predators spook them or try to eat them their tails come off and if the humidity goes down they will only grow their tails back a little bit looking like a little nub. They also might have stuck shed on their skin because of the humidity their skin will be dry and not moist so then their shed will be dry and won't come off and will be stuck and itchy for them.
