The three types of reefs are fringing reefs, barrier reefs, and atolls. Fringing reefs grow close to the shorelines of islands or continents, barrier reefs are separated by a lagoon from the land, and atolls are circular coral reefs surrounding a central lagoon, often found in the open ocean.

Great barrier reefs are actually on top of the dead and old reefs and sea anemones. So the non living reefs are the foundations and support for the living reefs.

Coral reefs can take four forms; fringing reef, platform reefs, barrier reefs and atolls. Fringing reefs are narrow and shallow, and generally occur near the shore, they literally are a thin 'fringe' along the coast. Platform reefs are reef outcroppings far from shore that occur in calm water. They often have a shallow lagoon, and are flat on top. Barrier reefs are reefs growing along a coastline that are separated from the coastline by a lagoon. Barrier reefs are very similar to fringings except that they are much larger. Atolls are ring reefs that usually form at the base of a volcano. Over time the volcano dissapears, leaving a rin of reef surrounded by deep ocean.

In the Caribbean, there are primarily three types of reefs: coral reefs, fringing reefs, and barrier reefs. Coral reefs are the most diverse and are typically found in shallow waters, while fringing reefs are directly attached to the shore, forming a narrow band along coastlines. Barrier reefs, on the other hand, are separated from the land by deeper lagoons and can be quite expansive. These ecosystems are vital for marine biodiversity and coastal protection.
