The teeth of sea snails are stronger than even spider silk

The natural composite material that forms the teeth of limpets -- "limpet" is the informal name for all aquatic snails -- is the strongest in the world. Researchers at the University of Portsmouth, in the south of England, confirmed as much after using atomic force microscopy to test the small-scale mechanical behavior of the teeth.

"Until now we thought that spider silk was the strongest biological material because of its super-strength and potential applications in everything from bullet-proof vests to computer electronics," said study leader Asa Barber, a professor at the university's School of Engineering. "But now we have ...
