The world's strongest natural material

Engineers in the UK have found that limpets' teeth consist of the strongest biological material ever tested. Limpets use a tongue bristling with tiny teeth to scrape food off rocks and into their mouths, often swallowing particles of rock in the process. The teeth are made of a mineral-protein composite, which the researchers tested in tiny fragments in the laboratory. They found it was stronger than spider silk. Which was formerly known as the strongest natural material.
