Biocalcification

Biocalcification is a natural process where living organisms produce and deposit calcium-based minerals, such as calcium carbonate or calcium phosphate, in their tissues. This process occurs in animals like mollusks, corals, and some fish, contributing to the formation of shells, skeletons, or other hard structures. It involves biological mechanisms that control mineral deposition, often for protection or support. Similarly, biocalcification can occur in other contexts, like the buildup of calcium deposits in tissues. Overall, it's a biological way of creating and maintaining hard structures essential for survival and function.
