Coral reefs support more organisms than any other marine environment. The money that can be made from dive tourism is much better than the income of a fisherman, so it is very important that governments and local people preserve the health of coral reefs. How diverse are coral reefs in global marine protected areas (MPAs)? Coral reefs are some of the most valuable ecosystems on the planet. There are sponges and corals of all shapes and sizes, hard and soft; tiny fishes like pygmy seahorses and big fishes like tiger sharks; there are anemones, nudibranchs and snails – the list goes on! 2018. They are home to about 25% of all marine life. However, if the stress is short-lived the coral can regain their zooxanthellae and survive. Photo: Nicole Helgason . The reefs act as nurseries for juvenile fish and protect them as they grow large enough to head out away from the reef. The variety of species living on a coral reef is greater than in any other shallow-water marine ecosystem, making reefs one of the most diverse ecosystems on the planet. While many MPAs have large numbers of species, the evolutionary diversity among those species is actually quite small. Extrinsic and intrinsic factors, physical and biological factors, and the interactions of all these are hypothesised to affect the diversity of coral reef-associated faunas. Coral reefs are living organisms that provide an important ecosystem for a variety of marine life. Coral reefs are also living museums and reflect thousands of years of history. Fortunately, scientific research shows us that corals can adapt to changing climates. The Value of Coral Reefs . This is a remarkable statistic when you consider that reefs cover just a tiny fraction (less than one percent) of the earth’s surface and less than two percent of the ocean bottom. Close this message to accept cookies or find out how to manage your cookie settings. Coral reef diversity Because of the diversity of life found in the habitats created by corals, reefs are often called the "rainforests of the sea." Occupying less than one percent of the ocean floor, coral reefs are home to more than twenty-five percent of marine life. Reefs are also diverse in types of habitats: fringing reefs, barrier reefs and atolls to name a few. Raja Ampat in particular attracts divers from around the world thanks to is incredibly diverse coral reefs. It’s all based on coral — small marine animals that build themselves stony skeletons, often on top of older corals. (Image credit: Dan Norton Coral.org) Coral reefs under siege. Coral reefs are one of the most diverse ecosystems on the planet and are home to 25 percent of all marine life though they occupy less than one percent of our oceans. Coral reefs are some of the most valuable ecosystems on the planet. Coral reefs are vital to our planet. High diversity on coral reefs—a very big game of rock-paper-scissors . Corals in Tela Bay on the mainland of Honduras are thriving in murky waters. C overing less than one percent of the ocean floor, coral reefs support an estimated 25 percent of all known marine species. ROB - Healthy coral reefs are amongst the most biologically diverse, culturally significant, and economically valuable ecosystems on Earth. SHARE . Broader application of gradient analysis to diverse taxa in the future may sharpen understanding of processes leading to modern patterns of diversity. These unique tropical environments harbor a high diversity of corals, reef invertebrates, fish and other animals and plants. Right after most coral reef fish hatch, they join a swirling sea of plankton as tiny, transparent larvae. Two sites in this region are showing promising signs of adaptation. Economic Value Beyond their intrinsic value and their role as a breeding ground for many of the ocean's fish and other species, coral reefs provide human societies with resources and services worth many billions of dollars each year. Coral reefs are important for a number of reasons. 4. This may not seem logical until you think about the way ocean currents work. In fact it is thought that there are still large numbers of undiscovered marine species that call coral reefs … Functions of Coral Reefs: Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet. Coral reef bleaching is also a growing concern. When corals surprise us by doing particularly well in unexpected places, it suggests that they may have already adapted to some of the threats that are facing coral reefs. Fish and other marine animals live in coral reefs, we know this. Coral reefs support the highest known biodiversity of marine life, and constitute the largest biologically generated structures on Earth. and Reefs support unusually diverse animal communities with distinctive taxonomic structure and geographical distribution patterns. These ecosystems are wildly diverse — home to everything from crabs to sea turtles. Thus, corals are found primarily in the Caribbean, Florida and Brazil in the Americas while there is very little coral development in California, Chile or any American Pacific coast. In fact, coral reefs are some of the oldest and most diverse ecosystems on the planet. They are made up not only of hard and soft corals, but also sponges, crustaceans, mollusks, fish, sea turtles, sharks, dolphins and much more. Although geographically restricted to tropical seas and occupying only 0.1% of the earth's surface, coral reefs have globally important implications for marine biodiversity. There are more than 600 reef species, which is ten times the number in the Caribbean Sea. Biodiversity is the variety of living species that can be found in a particular place—region, ecosystem, planet, etc. They are made up not only of hard and soft corals, but also sponges, crustaceans, mollusks, fish, sea turtles, sharks, dolphins and much more. As a marine ecosystem, coral reefs are the most diverse and productive habitat supporting a quarter of all marine species. The plant life on and around a coral reef is also extremely diverse and plentiful. Importance. Now, with this being said it is important to put things in perspective. A coral reef represents community of living organisms. Coral reefs are some of the most diverse ecosystems in the world. Crame, J. Alistair Weiss, Linda C. However, did you know that around a quarter of the ocean’s fish come from reef habitats? About half of all federally … Benefits of Coral Reefs. Thousands of species of coral, fish, mollusc and other wildlife can live on one reef. Have a read of our blog to get to grips with the different coral reefs that can be found around the word! It’s all based on coral — small marine animals that build themselves stony skeletons, often on top of older corals. Then currents, winds and waves disperse them, frequently to different reefs. Coral reefs are often also known as the Rainforests of the Sea because it protects us from storms and provides 70% of our oxygen. They teem with life, with perhaps one-quarter of all ocean species depending on reefs. Oakland, CA 94612 USA | Contact: 1.888.Coral.Reef | info@coral.org | Policies & Disclosures, Maui 10-Year-Old Grows 900 Native Plants to Protect Coral Reefs, CORAL Wins The Climate Adaptation Leadership Award.
