Figure 1.

Lamellar corpuscle structural parameters. (a) Corpuscle outer radius versus animal mass. The colour and shape of the data points reflect taxonomic class. Outer radii listed in pixels in table 1 are excluded. (b) Average lamellar thickness in the outer core versus animal mass. Lamellar thicknesses listed in pixels in table 1 are excluded. (c) Average lamellar thickness/corpuscle radius versus animal mass for all animals, including those excluded from (a,b). (d) Number of outer core lamellae versus animal mass. None of the plots shows a consistent trend with animal mass, and the wide structural variability across species is evident.
