Coral species that build reefs are with their calcium carbonate or aragonite skeletons are known as stony corals. Common shapes of coral are: massive, tabular, branching, encrusting, foliaceous, and columnar.
Branching corals have Tree-like morphologies.
Elkhorn corals, a type of branching coral, have a unique growth structure with wide branches similar to antlers.
Encrusting corals stay low to the ground and spread across the hard bottom.
Massive corals are boulder-shaped corals that grow slowly such as the Brain Coral.
Like massive corals, submassive coral grow to large sizes, however they have a lumpier shape.
Cup corals a non reef building coral with large polyps.
Foliose corals have a swirl-like pattern that resembles the shape of an open flower.
Mushroom corals are flat, round shaped solitary corals that live unattached to the substrate under them.
Table corals grow large horizontal structures like a flat tabular surface. This gives the coral more surface area on top for their symbiotic algae to gather light.
Colonies of columnar corals are formed by many cylindrical structures.
Instructions: The colored circles show where clusters of coral are located. The number shows the count of reefs in that location. Darker circles indicate greater concentration Click a circle to zoom in.

Since 2012 UM has planted approximately 600 meters of healthy coral back into the reef. The UM nurseries presently hold more than 2,500 corals to be used for the purposes of restoration.
