Limpets' teeth consist of the strongest biological material, scientists say

Engineers have discovered that the teeth of a limpet are made up of the strongest natural material ever tested - beating spider silk and most man-made materials.

The findings, published in the Royal Society's journal Interface, suggest that the secret to the material's strength is the thinness of its tightly-packed mineral fibres.

Dr Asa Barber, from the University of Portsmouth spoke to the BBC about the discovery.
