Although the term coral is often used in a general sense, it usually refers to reef or hard corals, which are more formally called scleractinians. These are the corals that may form large coral heads and which are the primary building blocksof coral reefs in tropical oceans: The common characteristic of. this group is the secretion of a basal skeleton of calcium carbonate as the mineral aragonite.
Coral reef. Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine water that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support and protect the coral polyps.
