Perhaps the most valuable function of the Chesapeake Bay region is its role as a habitat for living organisms. The Bay and its surrounding watershed provide ideal habitat for many plant and animal species. Some of the better known inhabitants of the Bay include blue crabs, oysters, and striped bass. However the Bay also is home to many other species including several types of shark, shrimp, reptiles, amphibians, birds, mammals, submerged aquatic vegetation and much more.
American oyster: Crassostrea virginica - also known as the eastern, American or Atlantic oyster, was once plentiful enough in the Chesapeake Bay that seasonal harvests were in the millions of bushels. As recently as 100 years ago, oyster reefs were so massive that they posed a navigational hazard to ships. (learn more)

Chesapeake Bay Ecosystem: The physical processes that drive the Chesapeake Bay ecosystem sustain the many habitats and organisms found there. Complex relationships exist among the living resources of the Bay watershed. Even the smallest of creatures plays a vital role in the overall health and production of the Bay. Forests and wetlands around the Bay and the entire watershed filter sediments and pollutants while supporting birds, mammals, and fish. (learn more)
