Why and How Oysters Make Pearls

Остриге се бисере као одбрамбени одговор на страним објектима.

The process begins when some foreign body, such as sand, a parasite or some other organic material, manages to make its way inside the oyster’s shell and comes in contact with the mantle, a layer that protects the oyster’s internal organs, sometimes even damaging it.

The oyster’s body sees the invading substance as a potential threat, and in response the mantle begins to deposit a substance called nacre, also called mother of pearl, onto it. This is the same substance that coats the inner part of the shell.
