Figure 1

Representative drawing of the spider with the sections of interest. Coloured areas represent different results of the Young’s modulus measured by nanoindentation. (a) Section of the prosoma in the longitudinal direction (here the indented region is indicated). (b) Section of the leg in the transversal section with a detail of the hair section. (c) Section of the fang in the longitudinal direction. (d) Section of the fang in the transversal direction, on the base. (e) Section of the fang in the transversal direction, on the tip. The colour filling of the spider schematic is to be considered illustrative, as the exoskeleton is composed of many other parts, e.g. hairs, joints. Scale bars: 200 µm.
