Caiman Evolution

The caiman, known for its rough scales and sharp teeth, lives in the rivers of Central and South American rainforests. They are 6 feet long and weigh 80 pounds. They were feeding on fish, birds, crustaceans, and small mammals. Because of global warming, rainforests are expected to dry out and become more like a savanna habit. Because of this, the caimans will need feet that are clawed, yet not webbed. Their long tails must be shorter to hide better in the scarce undergrowth. Their transparent, protective eyelids must become accustomed to keeping dust out of the eye rather than water. The caimans must become more agile on land to catch birds and rodents more easily. Their scales must evolve a dull brown, like the dust that comes off dirt, to blend in with the new environment and stay hidden from predators.
