The ganoid, cosmoid, and elasmoid scales of fish have distinct characteristics that evolved to offer protection from different predators. In this research, the armored scales of Atractosteus spatula (alligator gar), Arapaima gigas (arapaima), and Latimeria chalumnae (coelacanth) are evaluated using a variety of techniques including mechanical testing, SEM, TEM, and AFM. Protective features are compared with emphasis on the correlation between strength at different scales and mechanical properties. Structural differences between the three scales lead to differing toughening mechanisms which may be imitated and incorporated into superior armor designs. This research is funded by AFOSR MURI (AFOSR-FA9550-15-1-0009).
