Fig. 1.
Curvature space-time plots for the contours of (A) a typical crawling cell and (B) the Shapere–Wilczek swimmer. To prevent a loss of detail at the edges, the curvature has been plotted over two contour lengths. Note the herringbone structure—regions of high curvature bifurcate at the front and travel to the back.

The crawling and virtual swimming velocities along the direction of polarization. Constrained least squares regression shows that the cells crawl 12 times faster than they swim.
