The sidewinder has a hornlike projection over each eye. It is nocturnal and lives in the burrow of another animal during the day. At night it comes out to hunt small rodents, such as pocket mice and kangaroo rats. It also like to eat lizards. This snake moves sideways, not straigth ahead. When it moves, it throws its body into waves and only two short sections ever touch the ground. As it travels, the snake leaves a trail of parallel J-shaped markings. The sidewinder can be found in California, Nevada and Utah, and south to Mexico.
