oyster shell
Pearl's rough home
The hard, hinged outer covering of an oyster, composed largely of calcium carbonate.
Oyster shells accumulate where oysters are harvested or consumed, historically forming middens along coastlines.
Crushed oyster shell serves as a calcium supplement for poultry, a soil amendment, and material for driveways and paths in coastal areas.
