A fringing reef, also called a shore reef,<ref name=CRISG/> is directly attached to a shore,<ref>[https://www.pmfias.com/coral-reef-fringing-reefs-barrier-reefs-atolls/ ''Fringing Reefs (Shore Reefs)''] at www.pmfias.com. Retrieved 2 Feb 2018.</ref> or borders it with an intervening narrow, shallow channel or lagoon.<ref name=CRA/> It is the most common reef type.<ref name=CRA>[https://coral.org/coral-reefs-101/coral-reef-ecology/types-of-coral-reef-formations/ ''Types of Coral Reef Formations''] at coral.org.

''Coral Reefs of the Indian Ocean: Their Ecology and Conservation''. Oxford: OUP, 2000, p. 136.</ref> They are usually less than 100&nbsp;metres wide, but some are hundreds of metres wide.<ref>Goudie, Andrew. ''Encyclopedia of Geomorphology'', London: Routledge, 2004, p. 411.</ref> Fringing reefs are initially formed on the shore at the [[low water]] level and expand seawards as they grow in size. The final width depends on where the sea bed begins to drop steeply. The surface of the fringe reef generally remains at the same height: just below the waterline. In older fringing reefs, with outer regions pushed far out into the sea, the inner part is deepened by erosion and eventually forms a [[lagoon]].<ref>Ghiselin, Michael T. ''The Triumph of the Darwinian Method''. Berkeley, University of California, 1969, p. 22.</ref> Fringing reef lagoons can become over 100&nbsp;metres wide and several metres deep. Like the fringing reef itself, they run parallel to the coast. The fringing reefs of the [[Red Sea]] are "some of the best developed in the world" and occur along all its shores except off sandy bays.<ref>Hanauer, Eric. ''The Egyptian Red Sea: A Diver's Guide''. San Diego: Watersport, 1988, p. 74.</ref>
