The humble rock-scouring limpet, which is not as storied as the barnacle, now has a claim to fame. The teeth of the snail-like creature are believed to be the strongest natural material yet found on the planet. British researcher Asa Barber of the University of Portsmouth says of the newly announced superlative, "Until now, we thought that spider silk was the strongest biological material because of its super-strength and potential applications in everything from bulletproof vests to computer electronics, but now we have discovered that limpet teeth exhibit a strength that is potentially higher.”
