Oyster reefs form as generations of oysters settle on top of one another, As older oysters die, their shells form the foundation for future oysters to set upon. These reefs form structural habitat that support a diverse assemblage of life, offering substrate for barnacles and other invertebrates, feeding grounds for birds, and refuge for fishes and other organisms. Oyster reefs are found along the East Coast, Gulf Coast, and West Coast of the United States, with different species of oysters occurring along each coast.
