Colloquium: Biophysical principles of undulatory self-propulsion in granular media
Daniel I. Goldman
Motion is a distinctive feature of life at every scale, ranging from the microscopic scale of molecular motors to the macroscopic scale of animals. The study of animal locomotion such as swimming and flying raises many natural physics questions, since the mechanics of the fluid medium determines the best strategies for motion. These questions become more difficult for granular media, since our understanding of the basic physics of granular media is still emerging. This Colloquium reviews recent progress in understanding the physics underlying a locomotion strategy of a desert dwelling lizard, the sandfish.
