Bone walker (Exteamix Camalonus) is a large creature that lives in the super heated deserts, so it needs lots of things to stay alive. The first thing is that it will mostly be awake in the night. It has a large under jaw, that is used for storing water and other food. It has a sail for thermoregulation. And it evolved a shell-like structure near its eye for protecting against the sandstorms.
