The most common reefs you will see are a fringing reef. Without an intervening lagoon to effectively buffer freshwater runoff, pollution, and sedimentation, fringing reefs tend to particularly sensitive to these forms of human impacts.
You can find fringing reefs growing around the coastlines of islands and continents. "They are separated from the shore by narrow, shallow lagoons"(Coral reef alliance).
Reefs grow where there are stronger wave patterns and currents, so the stronger currents and waves give more food to the ecosystem in order to create the reef structure.
Atolls are formed when fringing reefs continue to grow upward from a volcanic island that has sunk.
Fringing reefs get their name from being more shallow and closer to the shore than a barrier reef. They are fringing towards the sand unlike barrier reefs that are further out to sea, and in deeper waters.
Coral reefs are very useful even to humans, they can be harvested to make medications to treat cancers and other illnesses.
Giving reefs protection means that fish and their eggs and homes will also be protected. The shape of the reef comes from the hard shell of an animal called a polyp. It is the cluster of polyps growing together that makes the reef.
