Sandfish Locomotion
The picture shows the head of a sandfish, a lizard that can swim in sand using propulsion driven by the back undulations. Our paper developed physical, numerical and theoretical models to show how the propulsion is generated and how in the models to optimize kinematics for maximal forward swimming speed --a prediction in accord with the biological observations.

From the article "Mechanical models of sandfish locomotion reveal principles of high performance subsurface sand-swimming" by Ryan D. Maladen, Yang Ding, Paul B. Umbanhowar, Adam Kamor, and Daniel I. Goldman, in J. R. Soc. Interface (http://rsif.royalsocietypublishing.org/)
