Figure 1.

Sedimentation visualized. The shaded boxes define three known corners of the columella cell with appropriate cell walls drawn between. A, Typical distal-to-side movement profile of seven statoliths with 15 s between frames. B, Typical side-to-side movement profile with the nine statoliths falling the entire width of the columella cell with 30 s between frames. C, Identifies those statoliths in B that move either through a common vertical channel or those sedimenting individually through independent channels and shows the average vertical distances covered by statoliths in these two categories.
