Anterior progress of the interface of the anterior pseudopod and progress of the posterior end of a 3XASP cell are coordinated. No dramatic changes in total pseudopod volume, cell body volume, or cell surface correlate with expansion, extension, or retraction of the anterior pseudopod or with formation of a new lateral pseudopod. The figure is set up in the same way as Fig. 4, except that landmark tracks are not plotted; see the legend to Fig. 4 for descriptions of the panels.
