Coral reefs that extend from the edges of a coastline out to sea without a lagoon between the reef and the shore are called fringing reefs. Barrier reefs also surround coastlines but are farther off shore and they are separated from the shore by a lagoon. Atolls are circular reefs that exist in deep oceanic waters. Atolls enclose a lagoon and do not surround a land formation. These reefs probably originated on a volcano that either subsided or was submerged by rising sea levels.
