ABSTRACT
This chapter focuses on the study of nanomechanical response of abalone shells. It focuses on the nanomechanical response of different varieties of bivalves. The chapter provides an insight about the nanomechanical properties of a bivalve mollusc Saxidomus purpuratus shell. It then provides a brief account of the nanomechanical properties of fish scales. Shells are interesting structures with multifunctional abilities. Among the various types of shells, the mollusc shell is one of the most important and ancient biological ceramic composites. As the function of a shell is to provide protection to the body, which in a way acts as a natural body armor, it is of utmost importance to measure the nanohardness of the shells to assess the ability of the shell to perform its function. The novel nanoindentation technique is the best way to understand the mechanical properties of such hierarchical bio-composite. Pteropods are specialized marine gastropods that include free-swimming pelagic sea snails and sea slugs.
