Snail Teeth Surpass Spider Silk as the Strongest Natural Material

Scientists have discovered that the teeth of snails are stronger than spider silk, which was previously considered nature's toughest material. The teeth of limpets, a type of sea snail, contain tightly packed iron-based mineral fibers that give them exceptional tensile strength. Researchers found that these tiny teeth can withstand extreme forces without breaking, outperforming spider silk in strength tests. This discovery could inspire the development of stronger synthetic materials for use in engineering and manufacturing applications.
