There are three basic types of coral reefs so far. They are the : Fringing reefs, Barrier reefs and the Atolls.
Fringing reefs: they form along shorelines.
Barrier reefs: they are separated from the shore by a shallow body of water which is called a lagoon.
Atoll: they are actually a ring if corals with a lagoon in the centre and they form away from land. You can find most atolls at the Pacific Ocean.
