Introduction to Oysters
Oysters are a type of mollusk that belongs to the family Ostreidae. They are found in oceans worldwide and are known for their distinctive shell, which they use for protection. Oysters are filter feeders, using their siphons to draw in water and filter out plankton, algae, and other small particles. This unique feeding mechanism allows oysters to accumulate a wide range of nutrients, including proteins, vitamins, and minerals.
