TL;DR
A 2015 study revealed that snail teeth are stronger than spider silk, overturning prior beliefs about the strongest natural materials. This discovery could impact biomaterials research and applications.
In a groundbreaking study published in 2015, scientists revealed that snail teeth are stronger than spider silk, previously considered one of nature’s strongest materials. This discovery challenges long-held assumptions and could influence future biomaterials research.
The research, conducted by a team of biologists and materials scientists, measured the tensile strength of snail teeth and compared it to that of spider silk. Results showed that snail teeth exhibit a higher resistance to breaking under stress, surpassing spider silk in durability.
According to the published paper, the unique composition of snail radula (the tongue-like structure with rows of teeth) includes a mineralized, hard, and flexible material that contributes to its exceptional strength. The findings suggest that snail teeth could serve as a model for developing new, high-strength biomaterials.
Implications for Biomaterials and Material Science
This discovery matters because it shifts the understanding of natural materials’ strength, opening new avenues for biomimicry in engineering. Materials inspired by snail teeth could lead to the development of more durable, lightweight, and flexible substances for use in medicine, manufacturing, and technology.
It also prompts scientists to reevaluate other biological materials that might possess underestimated strength, potentially leading to innovations in various industries.

Previous Assumptions About Natural Material Strengths
Prior to this study, spider silk was widely regarded as one of the strongest natural materials, valued for its combination of strength and elasticity. It has been used as a benchmark in biomaterials research for decades.
The 2015 research shifts this paradigm, highlighting that some mollusk structures, specifically snail radulae, may surpass spider silk in strength. This finding was based on comparative tensile tests and microscopic analysis of the materials’ composition.
Scientists have long studied biological materials for their potential in creating advanced synthetic substances, but this study emphasizes the importance of exploring a broader range of species and structures.
“Our findings reveal that snail teeth are not only incredibly durable but also surpass spider silk in strength, which could inspire new biomimetic materials.”
