By Miguel Rodriguez. What is a Coral Reef?. Coral reefs are diverse underwater ecosystems held together by calcium carbonate exoskeletons secreted by corals, which support and protect the coral polyps.. Rebecca Cebulka. What are Corals?. Marine invertebrates that live in colonies. Similar to anemones. Some can catch small fish and plankton. Typically live in deep ocean. Most obtain nutrients from symbiotic algae which live in the coral’s tissues. Built entirely by biological activity. CaCO. 3. solubility low above 20. o. isotherm. Radioactively labeled Ca absorption low on cloudy days. Global distribution limited by temperature. 70 m is max depth (1-2% surface illumination). By Harsha Lakamsani. Introduction.
