Eastern Oyster
Crassostrea virginicaAlso known as Atlantic Oyster, American Oyster, East Coast Oyster, Virginia Oyster
Eastern oysters are tireless ecosystem engineers that construct massive, complex reef structures in shallow estuaries and bays. A single adult can filter up to 50 gallons of water a day, dramatically improving local water clarity and quality. These living reefs provide critical nursery habitat for hundreds of marine species, from tiny crabs to economically vital sport fish.

Shells are razor-sharp; wear thick-soled footwear when exploring reefs and handle live clusters with care.
Oyster reefs have declined by over 85 percent globally due to historic overfishing, disease, and siltation.
Avoid stepping directly on live reefs to prevent crushing fragile young oysters, known as spat.- Watch the tides: Visit oyster reefs during low tide to see the extensive structures they build.
- Protect your feet: Wear sturdy, closed-toe water shoes to avoid painful cuts from razor-sharp shell edges.
- Support restoration: Participate in local shell-recycling programs to help build new reef foundations.
