In 1898, a dredging boat in Chesapeake Bay pulled up a set of human dentures with a live oyster firmly attached. The specimen, now at the Smithsonian Institution, shows how abundant oysters once were: they attached to almost any hard surface. Today, more than 99% of the bay's historic native oyster population has disappeared due to overharvesting, pollution, disease and habitat loss. The loss has devastated the bay's natural water-filtering system. In the late 1800s, oysters could filter the entire Chesapeake Bay in days; today it takes nearly a year. Conservation groups and state agencies are rebuilding reefs using crushed stone and hatchery-raised oysters, but progress is slow.
