Desert is a hard place to live. However, some species of snakes, lizards and bugs are very adapted to this hostile environment. For example, the fringe lizard burrows under the hot surface of sand to escape predators and heat, the sandfish lizard swims in sand as a fish and the rattlesnake lifts alternatively his body in order to climb steep dunes. We are inspired by these strategies to study the mechanics of granular media in toy-model experiments. This approach reveals the mechanisms underlying theses strategies and allows to predict the energetic cost for the animal kingdom.
