Question: Why do oysters grow pearls?
Why do oysters grow pearls?
Answer: We all know that pearls come from oysters, so don't be surprised if you crunch down on the beginnings of a pearl while munching your meal.

Pearls are formed when a piece of grit, sand or shell get trapped inside the oyster. It protects itself from irritation by secreting a nacreous liquid around the particle which eventually over time builds into a pearl.

If you partake in oyster shooters, which are swallowed rather than chewed, your teeth will be spared. Yet it almost seems a waste to swallow pearls of the ocean without savoring the flavor.
