Table 1.

Young's modulus of cuticle samples, measured by double indentation (average and standard deviation). There were three treatments: drying in air (4 h and 5.5 months), fixation in Bouin's fluid and scraping away the top part of the sample. The results before and after the treatment were compared with an n-way ANOVA, and the p-value is given.

	Young's modulus (GPa)	p-value
fresh samples	5.1 ± 1.3
drying 4 h drying 5.5 month	5.00 ± 0.56 5.22 ± 0.73	0.51
after fixation	5.05 ± 0.55	0.91
thinner sample	5.10 ± 0.55	0.65
