Some mollusks live in shells made of calcium carbonate, but they do not have exoskeletons like insects do.

Yes, coral does have exoskeletons made of calcium carbonate. These exoskeletons provide structure and support for the coral polyps, which are tiny organisms that secrete the calcium carbonate to build the coral reefs. Over time, these exoskeletons accumulate and form the large coral reef structures we see in the ocean.
Jacques-Yves Cousteau recognized that coral reef exoskeletons were composed of calcium carbonate dissolved in CO2 production because of his extensive research in the underwater world.
No, insects and roundworms do not have calcium carbonate shells. Insects have exoskeletons made of chitin, a tough, flexible protein. Roundworms lack a hard outer covering and have a smooth, cylindrical body shape.
Jacques-Yves Cousteau recognized that coral reef exoskeletons were composed of calcium carbonate dissolved CO2 production, thanks to his research in the underwater world, field not covered by marine biologists.
Starfish actually have ENDOskeletons, not exoskeletons. They are made up of calcium carbonate compounds called ossicles.
The carbonate. Calcium is neutral.

Calcium carbonate.
Calcium in the diet is necessary for strong bones and teeth. It is also used in blood clotting, nerve regulation, and muscle contraction. Calcium carbonate is a major biological structural material, especially in mollusc exoskeletons.
