Sea snail teeth found to be the strongest biological material ever tested

It’s stronger than spider’s silk and any man-made material.

Underneath their unassuming appearance, these creatures seem to be organically creating the strongest material ever to be tested.

The sea snails, which attach themselves to rocky shores of the sea, can be easily recognised for their cup-shaped shells which usually only reach few inches in size.

The limpets feed on algae, by using tongue bristling with tiny teeth to scrape food from rocks.

Engineers found that the teeth are made from a mineral-protein composite, which they are made up of tightly-packed mineral fibres. 

The findings were published in the Royal Society's journal Interface.

The material is so strong that it has been suggested that this research could go on to help improve the building dental fillings, F1 cars and aircraft.

The study's lead author Dr Asa Barber said”: These teeth are made up of very small fibres, put together in a particular way - and we should be thinking about making our own structures following the same design principles."

In terms of the materials strength, the measure has been compared to the pressure needed to turn carbon into a diamond, beneath the earths crust. Dr Barber compared the material to that of a single string of spaghetti holding up 3,000 half-kilogram bags of sugar.
