In this region the conditions are ideal for the abundance of marine biodiversity. From a distance, coral looks like mossy rock or bone, but up close it appears to be covered in tiny flowers. [more information needed] Therefore, players can manually load every piece of coral reef struc… Approximately 300 species of hard corals have been found in the Red Sea. Where are coral reefs found. Considering that sunlight only reaches down some 200 metres (656 feet) into the ocean, that's a crazy place for a photosynthesising species to call home. Coral reefs have existed on Earth for 500 million years, providing shelter and food to many generations of ocean life. You must be signed in to discuss. Thus, the Earth’s coral reefs are mainly concentrated towards their western margins (see global map, below), a distribution pattern that generally corresponds to the occurrence of shallow submarine platforms within tropical seas. It will be empty and seems more dangerous. Though they may look like colorful plants, coral are in fact made up of tiny animals called polyps. Corals, and the algae inside their polyps, rely on sunlight to produce the energy needed for them to survive and grow. They normally grow very slowly, not more than 10 cm a year. Coral reef biodiversity in the Red Sea is characterized by having a high endemism (are found nowhere else). The Red sea coral reef ecosystem is located in the north region of the Indian ocean, between the Africa and the Arabian Peninsula, and extends for 2,000 km (1,240 miles) along the shoreline, which consist mostly of fringing reef formations. Unlike other coral reef ecosystems at the tropics, the coral reefs in the Red Sea have adapted to variable temperatures. From the approximate number of more than 1200 fish species, it has been estimated that about 10% species of fish found in this region are endemic. Worldwide, coral reefs cover an estimated … © 2017 Actforlibraries.org | All rights reserved )—was about 4,265 years old. The average surface water temperature in the summer is about 26 °C (79 °F) in the north and 30 °C (86 °F) in the south with a temperature variation of 2 °C (3.6 °F) during the winter. So D is out. However, coral reefs are not randomly scattered throughout each of these great ocean basins (see map below). As a hiding place for some species of marine living beings Researchers have found five coral reefs in the Gulf of Mexico that no one knew existed before. Certain preservatives in sunscreens can also be toxic to reefs and humans. Corals are also found farther from the equator in places where warm currents flow out of the tropics, such as in Florida and southern Japan. The greater  variety of coral reef formations and biodiversity sets this region apart from other coral reefs in the world. Coral reefs are found in all three of the Earth’s oceans that have portions in the tropics – the Atlantic, Pacific and Indian. As communities established themselves, the reefs grew upwards, pacing rising sea levels. The biodiversity in the Caribbean coral reef ecosystem comprises approximately 65 known species of hard corals and an approximate number of between 500-700 fish species. Discussion. Coral Reefs can be found in all oceans. Each species of hard coral differs somewhat in their ability to tolerate variations in these environmental factors, but each does best only within an even more narrowly defined set of “optimal” conditions – and shallow tropical seas are those parts of the oceans where “optimal conditions” for coral growth are most frequently found. found off the coast of Hawaii was about 2,742 years old. Barrier coral reefs; Barrier reefs are found far away from the seashores. Corals are colonial invertebrates (animals without backbones) that excrete a calcium carbonate skeleton. Um, So how … These are the homes of approximate 2 million marine species including fishes, turtles, sea horses, lobsters, crabs, shrimps, algae, sharks, urchins, sponges, clams, octopuses, monk seals, and much more. Not only are deep-sea corals more diverse than ocean scientists ever imagined, they are also amazingly old. Coral Gardening Coral reefs support over 25% of marine life by providing food, shelter and a place for fish and other organisms to reproduce and raise young. Oct. 16, 2019 — Threats to coral reefs are everywhere -- rising water temperatures, ocean acidification, coral bleaching, fishing and other human activities. Corals can be found throughout the world’s oceans, in both shallow and deep water. The corals and algae have a unique relationship. Coral reefs are the ocean’s most diverse and complex ecosystems, supporting 25% of all marine life, including 800 species of reef-building corals and more than one million animal and plant species. The water exchange between the Red Sea and the Indian ocean is minimum, allowing the development of unique characteristics which distinguishes this reef ecosystem from other reef ecosystems of the world. Most importantly, zooxanthellae supply the coral with food. Coral reefs cover approximately 26,000 square kilometers (10,039 square miles) around the Philippines.
