What may look like one coral is actually a colony of thousands of coral polyps living very close together. Inside the tissue of a coral polyp, zooxanthellae (plant-like cells) make their home. The coral and zooxanthellae work together to survive. Hard corals have a skeleton that supports them. It is made out of the same substance that shellfish use to make their shellsââcalcium carbonate.
