Strongest biological material

Last updated: December 10, 2017 at 5:29 am

Limpet teeth – The radula (tongue) of a limpet is covered in tiny teeth (less than 1 mm) that are made of a mineral-protein composite up to five times stronger than spider silk, and most man-made materials. The teeth actually excavate rock as the limpet feeds.
