TL;DR
A 2015 study revealed that snail teeth are stronger than spider silk, making them the strongest natural material known. This discovery could impact biomaterials research and bioinspired engineering.
Research published in 2015 confirmed that snail teeth are stronger than spider silk, previously considered one of the strongest natural materials. This finding challenges existing assumptions and may influence future biomaterials development.
The study, conducted by researchers at the University of California, Riverside, measured the tensile strength of snail radula teeth and compared it to spider silk. Results showed that snail teeth have a higher breaking strength, making them the strongest known natural material to date.
This discovery was published in a scientific journal in 2015 and has since prompted renewed interest in the structural properties of mollusk teeth. The research team used advanced microscopy and mechanical testing to quantify the strength and durability of snail radula teeth, revealing their exceptional resilience.
Implications for Biomaterials and Bioengineering
This finding matters because it expands the understanding of natural materials’ strength, opening new avenues for bioinspired design. Materials mimicking snail teeth could lead to stronger, more durable biomaterials for medical, industrial, and technological applications.
It also challenges the long-held perception that spider silk is the strongest natural fiber, prompting further research into other biological materials that may surpass previous records.

Historical Perspectives on Natural Material Strength
Spider silk has long been celebrated for its combination of strength and elasticity, often cited as one of the strongest natural fibers. Prior to the 2015 study, the general consensus was that spider silk held the record for natural material strength.
The 2015 research shifted this view by demonstrating that snail radula teeth, which are used for scraping and feeding, possess a structural composition that grants them superior tensile strength. The study employed modern testing methods to quantify these properties, marking a significant development in biomaterials research.
“Our findings show that snail teeth are remarkably strong, even surpassing spider silk, which was previously regarded as the strongest natural material.”

Unanswered Questions About Snail Teeth Durability
While the 2015 study confirmed the exceptional strength of snail teeth in laboratory conditions, it remains unclear how these properties translate to practical applications or how they perform under different environmental stresses. Further research is needed to explore their wear resistance and long-term durability in real-world settings.
Additionally, the variability among snail species and how this affects their radula strength is still being investigated.
