Pssssst... Let me tell you a secret! There are snakes in the desert! Snakes are highly adaptive animals mainly because they are cold blooded. They need heat on the outside to maintain their body temperature, and it is unlikely they would overheat because direct sunlight for them to even be able to move. They also have water tight skin which prevents unnecessary water loss. Snakes are also ideal for living in the desert because their need for water is quite low.
