Fig. 2. Claw geometry. (A) Claw shape of the hind-, mid- and forelegs (drawings are
based on SEM micrographs). (B) Five arcs used for quantitative description of
the claw geometry (see Table
2). (C) Cross-section model of the claw for stress calculation.
The model is based on SEM data (see Fig.
3E,F). The claw consists of three parts in its cross section: (1)
a dense layer of the exocuticle (gray), (2) a loosely packed endocuticle, and
the claw lumen. Semicircular (A') and rectangular (B') parts of
the claw were calculated separately. XA,
XB and XT are bending centers of
sections A, B and A+B, respectively. For an explanation of
other symbols, see text, Table
3 and Appendix B.
