Seashells are primarily made of calcium carbonate, which is a mineral that is also found in corals and pearls. This material is secreted by mollusks such as snails, clams, and oysters to form their shells, providing protection and structure for the soft tissues inside.
Seashells can feel smooth, cool, and hard when touched, as they are made of calcium carbonate. The texture may vary depending on the type of shell and its condition.
Seashells are not classified as rocks. They are composed of calcium carbonate and formed by marine animals as protective outer coverings. While they may be found in rocky areas, seashells are biogenic, meaning they are produced by living organisms, whereas rocks are inorganic solid materials.
There are thousands of different varieties of seashells. Estimates range from around 50,000 to over 200,000 different species of seashells.
Seashells are primarily made of calcium carbonate, a mineral compound that is formed by marine organisms from the ocean water. This compound forms the structural material of the shell, providing strength and protection to the creature inside.
A rock made entirely of seashell fragments is known as a coquina. Coquina rocks are formed from the accumulation and compression of broken seashells, creating a unique and porous sedimentary rock that is often found along coastal regions.
