The coral reefs existing today began growing as early as 50 million years ago. Most established coral reefs are between 5,000 and 10,000 years old. Although size can be a good indicator of the age of a coral reef, it is not a certain indicator.he coral reefs existing today began growing as early as 50 million years ago.

Lack of light will of course kill a reefâno live coral growth takes place below about 50 metres under the surface. Hence thick atolls such as Eniwetok require the ocean floor to sink as the coral builds.As the coral is lowered, faster growth is possible than that which we measure at the surface.his is a living reef resting on an extinct volcano cone which comes up about three kilometres (two miles) from the ocean floor. Drilling revealed about 1,400 metres (4,600 feet) of reef material.
