The Window Amphibian

My future animal is a mutation of the poison dart frog. By the time my animal has inhabitated the Earth, it will be very dry, hot, and hard to find food. My mutated animal, (The Window Amphibian), has to camouflage to its surroundings. It does this by its outer layer of skin to a transparent layer in which it will cool off and also camouflage to its surroundings. My animal would be prey and it camouflages into its surroundings so that its predators cannot distinguish between my animal and its surroundings. The earth will be very warm and dry in the next 500 years and the rainforest would be very dry. The poison dart frog would need to adapt to a low rain percentage every year. My animal, the original, poison dart frog currently needs a lot of water to survive, and it will have to conserve its water usage.
