Biomimetic Application Ideas

Composite tools or machines for cutting (including on the nano- or micro-scales) More durable agricultural tools and implements

[Collapse all sections] Summary

"Another mollusk, the limpet Patella, backs the magnetite cutting tips of its radula with silicon dioxide (Runham et al. 1969). Incidentally, mollusks renew their radulas from the back as they wear near the front much the way elephants renew their teeth." (Vogel 2003:333)
