Snails’ Teeth: The Strongest Natural Material on Earth

Discovery of the Strongest Natural Material

Researchers have discovered that the teeth of marine snails, known as limpets, are the strongest natural material on Earth. This discovery is groundbreaking, as it surpasses the strength of previously known natural materials like spider silk and even diamond in certain aspects.

How Snails Use Their Teeth

Limpets use their teeth to excavate rocks as they feed. Their teeth are located on a tooth-studded tongue called a radula. The radula is incredibly strong and durable, allowing limpets to grind down rock with ease.

Composition of Snails’ Teeth

Scientists have determined that snails’ teeth are composed of a mixture of goethite nanofibers encased in a protein matrix. Goethite is an iron-containing crystal, and the protein matrix provides additional strength and flexibility to the teeth.

Strength Comparisons

When tested, the teeth of limpets were found to be about five times stronger than most spider silk. They are also stronger than Kevlar and comparable to the highest quality carbon fibers. In fact, a single strand of spaghetti made from this material could hold up about 3,300 one-pound bags of sugar.

Potential Applications

The discovery of the strength of snails’ teeth has opened up new possibilities for engineering applications. Engineers are now looking to snails as potential nature consultants for the development of strong and durable materials, structures, and even machines.

Other Strong Natural Materials

While snails’ teeth are the strongest natural material discovered to date, there are other rare natural materials that can withstand more stress than diamond. These include:

Wurtzite boron nitrate: A material with a diamond-like structure but containing boron and nitrogen.
Lonsdaleite: A hexagonal form of carbon that is created when graphite-containing meteorites impact Earth.

Tensile Strength and Hardness

It is important to distinguish between tensile strength and hardness when discussing the strength of materials. Tensile strength refers to the capacity of an object to resist pulling apart, while hardness refers to its resistance to scratching or cutting. Snails’ teeth have exceptional tensile strength but are not as hard as diamond.

Conclusion

The discovery of the strength of snails’ teeth is a testament to the incredible diversity and resilience of nature. These tiny creatures have evolved a remarkable adaptation that has inspired engineers to explore new possibilities for the development of strong and durable materials.
