Sand dollars do not molt in the same way that some other marine animals, like crabs or lobsters, do. Instead, they grow by gradually adding layers to their exoskeleton, which is made of calcium carbonate. As they grow, they may shed tiny spines and other surface structures, but this is not considered molting. Their growth process allows them to maintain their hard structure while adapting to their environment.
