Do oysters molt as they grow?

Oysters do not molt like some other shellfish, such as crabs or lobsters. Instead, they grow by secreting new layers of calcium carbonate to their shells, gradually increasing in size. As they grow, they can also form new shell layers around the existing shell, but they do not shed their shells. This process allows them to adapt to their environment and can result in changes in shell shape and size over time.
