💡 Fun Facts
- A seashell was the home of a living mollusc, like a snail or a clam. When the animal dies, it leaves its shell behind.
- The spiral shape of many shells is created as the animal grows, adding a new, larger chamber onto its home.
- Over thousands of years, old seashells get broken down by the waves to become grains of sand.
