Nature designs organisms using primarily minerals and proteins as the structural components. Collagen is the most common protein for nature to architect the structures for diverse functions; among these architectures, there are a wide of variety of hierarchical designs with different toughening mechanisms. In this work, the toughening mechanisms and the illustration on how nature uses the hierarchical structures to give different functions to the organisms from nano-, micro- to macro-levels are studied by using the real-time small angle x-ray scattering and structural imaging on non-mineralized collagenous materials – skin, mineralized collagen materials - arapaima, carp and the “living fossil” coelacanth fish scales. Detailed analysis will be discussed in the presentation according to the various complicated hierarchical structures of biological collagenous materials. The hierarchical structural assemble information as well as the toughening mechanisms are provided to artificial processing and engineering.
