Nature is capable of producing materials of incredible strength, with spider silk one of the most celebrated examples. In 2015, a group of scientists made a game-changing discovery in this area, demonstrating that the teeth of clingy molluscs called limpets actually have the strongest tensile strength of any biological material. Drawing inspiration from these flinty fangs, the team has produced a composite biomaterial with extreme strength, which could provide a more sustainable alternative to high-performance materials such as Kevlar.
