The relationship between fish and coral reefs is a complex one. They possess small fangs but inject a potent venom. Websites and Articles on Coral Reef Animals: Coral Reef Education Article for Grades 6-12– National Geographic. Based on the densities of these rings, scientists can determine the environmental conditions at the time of secretion which can then provide a climate record spanning a considerable period of time. Several species of these porous animals inhabit reefs. (Picture adapted from Sea anemones are close relatives of corals. Indo- Pacific reef anemones are known for their symbiotic relationships with clownfish and anemonefishes. 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. Some species are known as cleaners, and set up cleaning stations along the reef. 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-). This teamwork is called symbiosis. They are formed by coral polyps, tiny animals that look a little like sea anemones. 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. These sediments can become suspended in the ocean water where they may then be carried and deposited ashore by waves. This includes around 2 million species of fish, crustaceans, molluscs, sponges, sea cucumbers and seaweeds. Coral feeding, nutrition, gender and reproduction    It explores the interdependent relationships between species in the coral reef ecosystem. The coral reef ecosystem is a diverse collection of species that interact with each other and the physical environment. Coral reefs play an important role in the supply of sediments or sands to beaches. There are lots of articles, different publications and even curriculum to download. Coral reefs ecosystem is one of the world’s most biologically diverse ecosystems, compared only by the tropical rain forest. Coral reefs: A source of nitrogen fixers Take a closer look at these encyclopedia books including information about animal habitats, behavior, and scientific classification. Carnivorous snails are capable of drilling holes into clams or other shelled animals and then eating them. Bibliography and additional readings. 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. The banded coral shrimp is an example of a cleaner shrimp. Browse our extensive collection of zoological career infobooks including animal training, animal rescue and rehabilitation and zoo careers. Top of Page. These locations happen to be ideal for growth, settlement, and survival of hard corals. The extent of protection gained from the reef is, however, dependant on a number of other factors including the reef size and structure. Although molecular nitrogen (N2), a type of macronutrient, is abundant in the atmosphere and ocean, few marine organisms can utilise nitrogen in this form. Choose sustainable seafood. Others swim in to eat. Coral reefs provide spots of brilliant color under the waves. Coral reef biomes are mostly located in shallow tropical regions of the Western Pacific, Indian and Atlantic Oceans. Kemp’s Ridley Sea Turtle. Coral Reef Plants. Coral reef ecosystems cover only 1% of the ocean, but 25% of marine creatures live in them. Each coral reef is made up of colonies of tiny animals called polyps. Some ancient corals, species such as massive Porites corals, can provide valuable climate records. Threats (Part II)    Together, these plants and animals form the coral reef ecosystem. Many of these animals work together as a team like the coral polyps and zooxanthellae. Sea snakes are rarely found on reefs but do inhabit the waters around reefs in the Indo-Pacific. Coral Reef Biodiversity Biodiversity is the variety of living species that can be found in a particular place—region, ecosystem, planet, etc. They are the primary builders of coral reefs and an integral part of almost every aspect of the ecology of coral reef ecosystems. Sea anemones are close relatives of corals. From fun and affordable field trips for students to amazing summer adventures, our camps combine education and entertainment in a way that connects people to the sea and sea life like nowhere else. 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. Approximately 25% of all marine life on the planet can be found in corals reefs. | © Pierre Fidenci Animal Sounds Animal Sounds Eels are one of the reef's top predators. | Coral can be found in tropical ocean waters around the world. Coral have a dazzling array of shapes and colors, from round, folded brain corals (named for their resemblance to a human brain) to tall, elegant sea whips and sea fans that look like intricate, vibrantly colored trees or plants.Corals belong to the phylum cnidaria (pronounced ni-DAR-ee-uh), a group that includes jellyfish, anemones, Portuguese man … Yet reefs are destroyed in an instant to make souvenirs for tourists. The physical structure of a coral reef is built by reef-building polyps. Coral reefs provide opportunities for a number of recreational activities such as swimming, snorkelling and SCUBA-diving and can attract visitors from across the globe. 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. Hidden beneath the ocean waters, coral reefs teem with life. Today, fish are considered to be one of the most important components of the reef as they support subsistence and commercial fishing activities and provide a valuable source of protein in people’s diet. Coral reefs are found in tropical oceans closer to the equator, which makes It as one of the most complex ecosystem on earth. Other animals that live on the coral reef include sea urchins, sponges, sea stars, worms, fish, sharks, rays, lobster, shrimp, octopus, snails and many more. Despite this, they are able to support a large number of marine organisms all of which require nutrients for development, growth and survival. Together, these plants and animals form the coral reef ecosystem. The people of SeaWorld Parks & Entertainment are truly and deeply driven to inspire on behalf of, to celebrate and connect with, and to care for the natural world we all share.

There are 1500 species of fish and 400 species of coral that live on the Great Barrier Reef alone. Fishes play a vital role in the reef's food web, acting as both predators and prey. Flatworms live in crevices in the reef. Many marine organisms found on coral reefs are rich in chemical compounds known as marine natural products (MNPs). Second of all, many other species of fish and small marine animals also find shelter and build a livelihood among the coral forests. Some species of sharks, skates, and rays live on or near the reef. 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.
