Did you know?

1. Biominerals help us keep our balance – gravity receptors called “otoconia” (made from very small calcium carbonate crystals) in the inner ear prevent us from toppling over.

2. You can tell the temperature of the sea millions of years ago by studying sea shells – measuring the ratio of calcium to magnesium or the isotopes of carbon and oxygen found in fossilised shells helps us to determine past climate conditions.

3. Sea shells can be used to repair bone – by integrating pieces of nacre (mother-of-pearl) into areas of missing bone.

4. Nacre is one of the strongest natural materials known and is superior to most artificial composite ceramics in terms of stiffness, strength and toughness.
