TL;DR
A 2015 study revealed that snail teeth are stronger than spider silk, redefining understanding of natural materials’ strength. This discovery has implications for biomaterials research.
In a 2015 scientific study, researchers confirmed that snails’ teeth are stronger than spider silk, marking a significant shift in understanding of natural material strength. This discovery challenges long-held beliefs that spider silk is the strongest biological material and has potential implications for biomaterials development.
The study, conducted by a team of biologists and materials scientists, measured the tensile strength of snail radula teeth and compared it to that of spider silk. The results showed that snail teeth possess a higher tensile strength, making them the strongest known biological material at the time.
According to the researchers, the strength of snail teeth is due to their unique composition, primarily made of a mineralized tissue reinforced with proteins, which provides exceptional durability and hardness. The findings were published in a peer-reviewed scientific journal in 2015, confirming the material’s superior strength.
Prior to this, spider silk was widely regarded as the strongest natural material, valued for its elasticity and tensile strength. The new evidence from this study positions snail teeth as a potential model for developing advanced biomaterials for industrial and medical applications.
Implications for Biomaterials and Engineering
This discovery matters because it challenges existing assumptions about natural materials’ strength and could inspire new biomimetic designs. Materials derived from or modeled after snail teeth might lead to stronger, more durable synthetic options for use in medicine, manufacturing, and engineering.
Furthermore, understanding the composition and structure of snail teeth could inform the development of new composite materials that combine hardness and flexibility, mimicking biological systems more effectively.

Previous Beliefs About Natural Material Strengths
Before 2015, spider silk was considered the strongest natural material due to its high tensile strength and elasticity, making it ideal for various biological and industrial uses. The discovery that snail teeth surpass spider silk in strength redefines the hierarchy of biological materials.
The research builds on prior studies of biomaterials, which have historically focused on spider silk, mollusk shells, and other biological tissues. The 2015 findings added a new perspective, highlighting the potential of mollusks as sources of high-strength materials.
“Our measurements show that snail teeth can withstand greater forces than previously thought, surpassing spider silk in strength.”

Unanswered Questions About Snail Tooth Composition
While the study confirms the superior strength of snail teeth, details about the exact molecular structure and how it can be replicated synthetically remain under investigation. The long-term durability and potential for industrial scaling are still uncertain.
Further research is needed to determine whether all snail species possess similarly strong teeth and how environmental factors influence their material properties.
