How does coral make calcium carbonate?
The skeletons of dead corals are the foundation upon which layerer upon layer of successively younger animals attach themselves. The coral animal, or polyp, is colulmn shaped. Its lower end is attached to the hard floor made of the preceding coral skeletons of the reef, and its upper end extends into the water. There hard and soft corals, depending on the type of skeleton secreted. The hard-coral polyp deposits a cup-like solid skeleton of calcium carbonate around itself into which the polyp withdraws during the daytime. For this reason, deep sea divers see only the skeletons-and not the polyps-of hard corals.
Why soft corals live in deeper water than hard corals?
soft corals live deeper water than hard corals because soft corals do not create a hard outer skeleton as the hard corals do.
