How Do Corals Build Their Skeletons?

Coral polyps—the tiny living soft-bodied coral animals—bring in seawater containing these ions, along with calcium (Ca 2+) ions, into a "calcifying space" between its cells and the surface of their existing skeletons. They pump hydrogen ions (H +) out of this space to produce more carbonate ions (CO 32-) ions that bond with (Ca 2+) ions ...
