Marine Shells
Marine shells refer to the protective outer coverings of various mollusks that live in the ocean. These shells are typically made of calcium carbonate and are used to provide protection and support for the soft-bodied animals inside. Marine shells come in a wide range of shapes, sizes, and colors, with intricate patterns and designs that are unique to each species. They are often collected for their beauty and diversity, and have been used for centuries in jewelry, art, and decorative objects.
