Definition Reefs dominated by massive corals (also known as boulder or mound corals) that are characteristically ball- or boulder-shaped and relatively slow growing. This group includes reefs dominated by submassive corals, which are similar to massive corals, but have a lumpier structure. Brain corals are an example of massive coral.

Massive and submassive corals are resistant to strong water currents, and are therefore commonly found in shallow and mid-depth waters. These forms are common on back-reef slopes. See Figure 8.5 for an example of the massive coral growth form.
