Each reef supports its own unique community of inhabitants and the Demographics of these communities are in a constant state of change. As a result, the inhabitants of coral reefs are many and diverse. There are, however, similarities in reef communities. For example, there are always 3 types of reef dwellers: 1. Builders: the organisms that caused the reef to be there at all, like the coral; 2. Exploiters: organisms that take advantage of the reef's protection and bounty, like fish. Some of these organisms add their hard skeletons or shells to the reef structure; 3. Destroyers, like the starfish that feed on the reef builders. Also, many types of animals are common to all, or most, coral reefs: fish, mussles, shrimp, lobsters, sharks, etc. Use the links to learn more about reefs and their communities, and how they interact.
Over fishing reduces the amount of breeding stock so the coral reefs become depleted of their natural fauna and the corals are not looked after by their normal inhabitants and subsequently die off. There is also the terrible damage done to the reefs by boats, walkers and also anchors ripping and smashing the coral to bits.
Coral reefs are made up of coral, the shell-like structures that the tiny sea animals build as their "houses". Each year, a living coral reef builds a new layer of coral; you might think of it as the collected skeletons of all the previous inhabitants of the reef. (Except that for coral, their "bones" are on the outside.)
