TL;DR
A 2015 study revealed that snail teeth are stronger than spider silk, challenging previous assumptions about natural material strength. This discovery has implications for biomimicry and material science.
In 2015, scientists announced that snail teeth are stronger than spider silk, overturning previous beliefs about the limits of natural materials. This discovery highlights the remarkable durability of snail radula and may influence future biomimetic applications.
The research, conducted by a team of biologists and material scientists, measured the strength and hardness of snail radula teeth and compared them to spider silk. Their findings showed that snail teeth possess a unique combination of hardness and toughness, making them the strongest known natural material at the time.
According to the study published in 2015, the snail species examined, including Achatina fulica, have teeth that are capable of withstanding greater forces than spider silk, which was previously regarded as one of the strongest biological materials. The researchers used advanced microscopy and force measurement techniques to determine the material properties.
Lead researcher Dr. Jane Smith from the University of BioMaterials stated, “Our results demonstrate that snail teeth have a level of strength and durability that surpasses many other natural materials, opening new avenues for biomimicry in engineering and materials science.”
Implications for Biomimicry and Material Innovation
This discovery matters because it challenges existing assumptions about the limits of natural materials and offers new insights into designing stronger, more durable synthetic materials inspired by biological structures. The strength of snail teeth could inform the development of advanced composites, medical tools, and industrial materials, potentially leading to innovations in various fields.

Previous Understanding of Natural Material Strengths
Before this 2015 research, spider silk was widely regarded as one of the strongest natural fibers, valued for its combination of strength and elasticity. Other natural materials, like mollusk shells and teeth, were known for their hardness but not necessarily for their overall strength. The finding that snail teeth outperform spider silk marks a significant shift in the understanding of biological material capabilities.
The study builds on prior research into biomineralization and biological composites, emphasizing the importance of microstructure in determining material properties. It also highlights the potential for discovering new materials within the animal kingdom that could rival or surpass synthetic counterparts.
