Healthy coral reefs are among Earth’s most biologically diverse and economically valuable ecosystems and are vital around the world. Without these important habitats in which to thrive, fish and sea life will cease to exist. Fisheries both large and small depend the coral reef either directly or indirectly, as a source of their livelihood. In developing countries, the reef is said to contribute to one-quarter of the total fish catch providing food resources for tens of millions of people. Coral reefs act as physical barriers between the ocean and land. Protects coastlines. The study of coral reef environments has always been quite far behind the study of other environments like rainforests. The purpose is to count and quantify the abundance and community composition of key fish species along 30-m long × 2-m wide belt transects and measure the relief of the reef. – Key fish species In recent decades many of the world’s coral reefs have suffered because of global warming, polluted waters and more direct human harm, such as through unethical overfishing. Coral reefs slow down the flow of water. Since most reefs thrive in shallow waters due to access to natural light, they are able to act as natural barriers for coastal regions. Firstly, and perhaps most obviously, protecting coral reefs is important as they are some of the most diverse ecosystems on earth. Coral reefs are among the most fascinating ecosystems of the world. The coral reef plays an important role in the protection of the coastline against erosion. Coral reefs teem with diverse life. A natural barrier that can adapt with increasing sea levels is especially important in these times. Studying these coral reefs is important because they provide a clear record of climatic events throughout history. Without coral the amount of carbon dioxide in the ocean rises, which in turn, affects all living things on Earth. to help us conduct our pioneering research on the interconnection between oceans and human health. Provide shelter to various species; Coral reefs provide food and safe shelter to many species of water kingdom such as shrimps, small fishes, and many other predators. Functions of Coral Reefs: Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet. As the foundation for complex food webs, coral reefs support an incredible diversity of fish. See also: Importance of Artificial Coral Reefs. Some coral reef organisms produce powerful chemicals to fend off attackers, and scientists continue to research the medicinal potential of these substances.

Protects the coastal areas from heavy water currents; Coral reefs play an essential role in slowing down the flow of water waves near coasts. Post was not sent - check your email addresses! There are three subclasses: Hexacorallia, Octocorallia, and Ceriantharia. The ridges in coral reefs act as barriers and can reduce wave energy by up to 97%, providing crucial protection from threats such as tsunamis. Due to their massive formation between the surface and the first few dozen meters of depth, coral reefs form a barrier that absorbs the elements coming from the open sea in a very efficient way.
