The Eastern oyster (Crassostrea virginica) is a bivalve mollusk native to the Atlantic coast of North America. It typically inhabits estuaries and coastal waters, where it plays a crucial role in the ecosystem by filtering water and providing habitat for various marine species. Eastern oysters are known for their distinctive irregular shells, which can vary in color and texture. These oysters are also significant for their economic value, as they are harvested for food and contribute to the seafood industry. They are often cultivated in aquaculture farms, helping to support local economies while promoting sustainable practices in marine environments.
