Fig 5. Results of fitting whiskers to an elliptical model are shown.

(A) Three exemplar whiskers fit to ellipses are shown. Solid curve: Whisker. Dotted curve: Fit elliptical arc. (B) For each species, the histogram shows the number of whiskers that occupy a given percentage of a ¼ elliptical arc. Values greater than 100% (vertical dotted lines) indicate that the whisker occupied more than ¼ of the elliptical arc. The histogram bin value adds up to the total number of whiskers shown in Table 1.
