The common limpet, an aquatic snail that clings on to rocks and can be found along shorelines all over the world, possesses teeth so strong that researchers had to resort to using a diamond saw in order to cut in to them.Their sheer strength, which is comparable to that of some of the strongest man-made materials, could prove invaluable in the construction of cars, boats, planes and even false teeth.

"The strength of limpet teeth is, on average, 4.9 GPa - that is like trying to break a piece of spaghetti with 3,000 bags of sugar," said study leader Professor Asa Barber.

"Limpet tooth strength is comparable to the fibres used in bullet-proof vests and the carbon fibres commonly used in composites for aerospace structures and Formula 1 cars."
