Around six thousand species of coral are there in the world. Some species thrive on the dark, cold seafloor of the open ocean, while some are growing in warm shallow waters near coastlines. Coral may look like a plant because they grow from roots in the seafloor, but they actually are an animal. The reason why they are known as colonial organisms is that many individual creatures live and grow while connected to each other. The individual organism is dependent on one another for survival. The coral reef is in the form of a cylinder, including a mouth at one end surrounded by
tentacles. The limb-like tentacles cluster food and sting creatures that threaten the coral. The polyps waste products exit through the mouth after the food is digested. Sometimes coral reefs are known as the rainforests of the sea. The availability of coral reefs is the first priority for many oceanographers and other marine conservationists because the world has lost nearly 20% of its coral reefs, with many more reefs under threat today. The main cause of coral reef; loss is pollution and increasing ocean temperature.
Amazing Coral Reef Facts
They are living organisms, although they look like a composition of rocks from a cursory view. The polyps or reefs become hard as they die and new reefs grow on top of them makes the reef grow. The coral reef has nutritional requirements as they are considered living due to their inhibition and their composition. The reefs consume small fishes and algae as algae need sunlight for photosynthesis. One of the major components of coral comes out at night of their skeleton to feed by stretching their tentacles to capture critters that are floating by. The coral reef is located in the Indo Pacific region, Australia, American, and African west and stretches for over 1200 miles. They are made up of calcium carbonate skeletons of the corals and are small immobile animals that are closely related to jellyfish. In northern Australia, the largest coral reefs are found, which is known as the Great Reef barrier that extends for over 1200 miles and can be visible from space. In Indonesia, the most diverse reef is found, with the western water bodies having 85% more diversity. Coral reefs are known as one of the major marine biomes and inhabit 25% of known marine species. Their formation provides various holes and crevices for species like crabs, fishes, shrimps, and many more. The coral reef lifestyle has been adopted by the species. Moreover, they help in medicinal discoveries such as medicines for cancer.
To conclude, even though the reefs are a small part of the marine system, but coral reefs; the facts are they carry a lot of importance for marine and human aspects, they need to be protected.
