Oyster reef

An oyster reef is an underwater structure built by oysters clustering together and cementing themselves to one another with a shell-like substance, creating a living community that can span large areas of the seafloor. These natural reefs provide critical services to marine ecosystems by filtering massive amounts of water, improving water quality, and creating habitats where hundreds of other species can thrive. Oyster reefs also protect coastal areas from storms and erosion, making them valuable both ecologically and for human communities who depend on healthy coastal environments.
