What is Coral?
Coral is a sea product that grows in branches, which look much like dwarf underwater trees. In the whole cycle of making of coral, a marine gelatinous animal collects calcium carbonate around its body. It is a polyp made of calcite fibrous crystals. The polyps then create a branch like shape, built in the shape of hollow tubes fitted in one another. This makes for a sort of axial skeleton upon which the boneless coral polyps grow.
