Limpet teeth rewrite record books

Engineers 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.

Prof Asa Barber from the University of Portsmouth spoke to the Today programme about the findings and how they might be applied to engineering problems.
