Some Interesting Oyster Facts
Aphrodisiacs... While there is no verifiable scientific proof that oysters are aphrodisiacs, history suggests otherwise. It is commonly believed that the high trace metal content of oysters could correct mineral imbalances in an individual, producing noticeable changes in certain physical functions and performances.
Are oysters male or female?
It is hard to determine the gender of an oyster because unless they are spawning, the sex organs are not visible. All oysters start off life as a male, but they are hermaphroditic and after one year can change to females. Within 3 years, 90% of oysters are female, so you can usually tell the gender of an oyster by the size: small ones are males, and large ones are females. An oyster cannot be male and female at the same time.
How do pearls end up inside of oysters?
An oyster produces a pearl when foreign material becomes trapped inside the shell. The oyster responds to the irritation by producing nacre, a combination of calcium and protein. The nacre coats the foreign material and over time produces a pearl.
