About Oyster
Oysters are bivalve mollusks found in marine and brackish habitats. They are highly prized for their unique flavor and texture, making them a popular delicacy worldwide. Oysters are also filter feeders, playing a crucial role in maintaining water quality in their ecosystems. They are commonly consumed raw, grilled, baked, or used in stews and chowders. Beyond their culinary uses, oysters are also valued for the pearls they sometimes produce, though not all oyster species are pearl-bearing. The size and shape of oysters can vary depending on the species and their environment, influencing their taste and use in different cuisines.
