The lagoon is not the former volcanic crater. For the atoll to persist, the coral reef must be maintained at the sea surface, with coral growth matching any relative change in sea level (sinking of the island or rising oceans). [4] An alternative model for the origin of atolls is called the antecedent karst model.
The class includes important coral reef builders such as the stony corals, sea anemones, and zoanthids. The recognized orders are shown below: [4] Actiniaria – sea anemones; Antipatharia – black corals; Corallimorpharia – corallimorpharians aka "false corals" †Rugosa – rugose corals; Scleractinia – stony corals †Tabulata ...
