Mechanical Optimization of Biomineralized Materials of Marine Origin

Abstract

Biomineralization is utilised by animals to form durable yet lightweight structures, e.g. bones, teeth and shells. Here we focus on the microstructure of the exoskeleton of the heart urchin because of its unusual strength. This species shares many features with sea urchins but deviates in appearance because it has adapted to withstand high pressures because it is buried in the sand.
