From: Exceptional properties of hyper-resistant armor of a hydrothermal vent crab
Crab samples and mechanical properties. The samples of the two species [(a) Austinograea sp., (b) C. japonica]. (c,d) The hardness and reduced modulus of the exoskeletons of the two crabs in cross-sections (mean ± SE). (e,f) The hardness and reduced modulus of the vent crab in cross-sections and in-plane sections14 (mean ± SE) [significant difference is indicated by an asterisk (*)].
