In this study, the teeth of the Great White (Carcharodon carcharias) and the Tiger (Galeocerdo cuvier) sharks are analyzed to find their structure-property relationships for optimized shearing and bite force. Towards this extent, the teeth’s chemical composition, density, material variations, geometric optimization, and the potential reduction in shearing forces when penetrating materials are evaluated. The structure-property analysis was conducted using scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDX), and optical microscopy in order to study the teeth’s hierarchical optimization. The structural property quantification also focused on the serrated edges of the teeth, which were captured in SEM and micrographs and were analyzed using ImageJ software. Macro- and nano-indentation will also be performed to determine the material’s hierarchy in optimizing the mechanical properties for ideal shearing and bite force. Further research will hopefully find a biological optimization for serration size, shape, and material.
