Fig. 9.

Temporal beat pattern of a 4-6-4 swimmer with cilia beat in an oblique direction (${\theta }_r=22.5^{\circ }$), with latitudinal wave vector $k_{\phi }=0$ and phase lag $\chi =-{77}^{\circ }$. The varying cilium color indicates the instantaneous stage in the beat cycle (compare Fig. 2). The progression of the beat is indicated by the time t, given in units of the beat period $\tau$. The motion of the swimmer is from left to right. The translational motion is not to scale. See also movie SM3 for an illustration of the swimming behavior
