In their book "Coral Reed Fishes", Ewald Lieske and Robert Myers estimated that there were at least 6,000 species of fish within the world's coral reefs. Coral reefs: A source of nitrogen fixers Around a coral reef live many animals such as sponges, mollusks, crustaceans, sea anemones, a wide variety of fish, and even the coral itself is an animal. The reef is also home to a variety of worms, including both flatworms and polychaetes. These sediments can become suspended in the ocean water where they may then be carried and deposited ashore by waves. There are lots of articles, different publications and even curriculum to download. | Coral reefs are one of the most biologically diverse ecosystems on earth, rivaled only by tropical rain forests. Eels are one of the reef's top predators. Coral reefs: A provider of medicines Increased ocean temperatures and changing ocean chemistry are the greatest global threats to coral reef ecosystems.

Coral derived sands are white in colour and have since become associated with tropical beaches although in many cases coral reefs not the sole supplier of sand to beaches as they can also receive sediments generated on land. The banded coral shrimp is an example of a cleaner shrimp. Clown Fish. Wrasses comprise a large group of colorful cigar-shaped fishes. Some polychaetes such as Christmas tree worms and feather duster worms bore into coral skeletons. The actual coral polyps are animals. This includes around 2 million species of fish, crustaceans, molluscs, sponges, sea cucumbers and seaweeds. However, as much as latitude is vital to the growth of coral reefs, currents are also important. Approximately 25% of all marine life on the planet can be found in corals reefs. Sponges provide shelter for fishes, shrimps, crabs, and other small animals. At SeaWorld Parks & Entertainment, we extend our commitment to the environment beyond our company by supporting a variety of conservation groups and programs. The coral reef, an underwater ecosystem that is the home of 25% of the oceans plants and animals, supports a food chain that includes thousands of different creatures, including the shark! Each polyp produces calcium carbonate, which makes up their skeleton and protects corals internal bodies; similar to how our skeleton protects our organs. Some species of sharks, skates, and rays live on or near the reef. Parrotfish use chisel-like teeth to nibble on hard corals. A healthy coral reef system can support a huge number of aquatic animal life. Site and Image use!

Hidden beneath the ocean waters, coral reefs teem with life. © Pierre Fidenci Scientists are still perplexed over … What are coral reefs? Other fishes found on the reefs include angelfishes, butterflyfishes, damselfishes, triggerfishes, seahorses, snappers, squirrelfishes, grunts, pufferfishes, groupers, barracudas, and scorpionfishes. On average, reef-associated fish catch can also account for one-quarter of the total fish catch in developing countries. These microscopic invertebrates from branching colonies over coral skeletons and reef debris, cementing the reef structure. Few economic valuations of MNPs are currently available, however a valuation model of anti-cancer drugs alone suggests that a 20% loss of coral reef biodiversity would equate to a market value loss of US$112 billion -1.14 trillion. They include sponges, starfish, anemones, cucumbers, snails, and clams. 18 Animals in The Coral Reef – Characteristics 1. Coral reefs provide essential shelter, feeding, nursery and spawning grounds for a number of marine organisms including reef-associated fish. Some of the most colorful animal species in the world make their home among the coral. In 2010, the global net benefits of reef tourism were valued at US$ 11.5 billion. The kemp’s ridley sea turtle (Lepidochelys kempii) is a small sea turtle … Today, the total number of reef fishers in each of Indonesia, Philippines, India, Vietnam, and China are estimated to be between 100,000 and more than one million. Although molecular nitrogen (N2), a type of macronutrient, is abundant in the atmosphere and ocean, few marine organisms can utilise nitrogen in this form. Bibliography and additional readings. They love to live in the sea floor and they also have... 3. Coral reefs provide habitat to a vast number of fish species while several types of fish such as the parrotfish protect and clean the coral reefs. They appear in a variety of shapes and colors. Both schooling and solitary fishes are essential residents of the reef ecosystem. Corals reefs are formed over a process of thousands of years. The skeletal composition of some coral species can provide historical accounts of local and regional environmental conditions. Together, they create such a symbiotic... 2. © Paddy Ryan These plants also provide a source of food for herbivorous feeders which allows nitrogen to enter the food chain. In developing countries, fisheries activities play a particularly important role as they contribute towards poverty alleviation by providing food, income and employment. Invasive species can create an imbalance in the biological checks and balances of a reef ecosystem. Coral reef ecosystems cover only 1% of the ocean, but 25% of marine creatures live in them. Coral reef biomes are mostly located in shallow tropical regions of the Western Pacific, Indian and Atlantic Oceans. Coral reefs are made of the calcium carbonate skeletons of corals – small immobile animals closely related to jellyfish.

An anemone's tentacles provide refuge for these fishes and their eggs. Paint the inside of the box blue. Coral reefs are large platforms of minerals. Coral associated bacteria, such as the photosynthetic cyanobacteria, are one of the few marine organisms that are able to take molecular nitrogen (N2) from the water and convert or ‘fix’ it to produce more usable products such as ammonia (NH3), ammonium (NH4+) and nitrate (NO3-) as well as the intermediate by products nitrous oxide (N2O) and nitrite (NO2-). The crown-of-thorns sea star is a well- known predator of coral polyps. Some sea turtles frequent reef areas. Threats (Part II)    Other medicines and treatments that have derived from marine organisms include AIDS inhibitors, anti-inflammatory and anti-coagulatants as well as use of coral bone grafts. Coral reefs provide shelter for nearly one quarter of all known marine species. This clam may reach a length of 4 ft. (1.2 m). This area supports more than 7,000 species of fishes, invertebrates, plants, sea turtles, birds, and marine mammals. Sponges have been a part of the coral reef ecosystem from early on. They grind the coral's exoskeleton to get the algae, and defecate sand. Coral reefs are generally found in low nutrient environments. As waves pass over a reef structure, their energy can be reduced by 75-95% which can lessen their impact as they reach the shore. © Pierre Fidenci Some species are known as cleaners, and set up cleaning stations along the reef. The value of shoreline protection from coral reefs, based on the anticipated loss of property, avoided damages (where reefs have been perceived to reduce wave inundation) and the cost of building artificial shoreline protection structures (to substitute a reef) was US$10.7 billion in 2010. Coral reefs provide spots of brilliant color under the waves. Coral reefs: Providers of climate records Coral reefs are not able to endure temperatures that plummet below 18 degrees Celsius. Coral reef frameworks can serve as physical buffers for ocean waves and currents. As they secrete calcium carbonate skeletons, they create a complex three dimensional framework upon which an abundance of coral species and other marine plants and animals may live. © Pierre Fidenci Several species of these porous animals inhabit reefs. Other familiar species include bristleworms. © Pierre Fidenci Many marine organisms found on coral reefs are rich in chemical compounds known as marine natural products (MNPs). Once converted, these ‘fixed’ nitrogen products can be utilised by marine plants that are equipped with special enzymes that reduce the nitrogen even further. Sponges provide shelter for fishes, shrimps, crabs, and other small animals. Although the buffering capacity of coral reefs is generally less effective against large storm waves, coral reefs can, in some circumstances, provide some protection again tsunami waves. Though individual corals can be quite small, they live with millions of other individuals, and over the course of hundreds of thousands of years, they build reefs that are absolutely enormous. Today, approximately 150,000 km of coastline across 100 countries and territories receive some protection from wave energy. Coral reefs support over 4,000 species of fish and thousands more species of plants and animals.

These fishes live in crevices in the reef and venture out at night to hunt and feed. Coral reef tourism creates livelihood opportunities and revenues generated contribute to national economies. Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. The width and density of calcium carbonate skeletons secreted by a polyp is influenced by the environmental conditions of the ambient seawater e.g., water temperature, hydrologic balance (evaporation, precipitation, runoff), and ocean circulation. First of all, the corals themselves live in symbiosis with algae, which is how they get their vivid and stunning colors. Coral reefs: Supporters of subsistence and commercial fisheries When they die, the minerals stay behind, slowly building up into huge reefs that provide shelter for vast numbers of other sea plants and animals. Sponges have been a part of the coral reef ecosystem from early on. Corals are animals, even though they may exhibit some of the characteristics of plants and are often mistaken for rocks. The extent of protection gained from the reef is, however, dependant on a number of other factors including the reef size and structure.
