- Coral reefs are the most diverse of all marine ecosytems.
- The value of coral reefs has been estimated at 30 billion U.S dollars.
- Corals can be found in both shallow and deep water.
- Coral reefs can also be found in three of earth´s oceans, the Atlantic , the Pacific, and the Indian ocean.
- Corals are ancient animals related to Jellyfish and anemones.
- The skeletons of many coral colonies,add up to build the structure of a coral reef.
- The coral reef is second only to rain forest in biodiversity of species.
- Coral reefs covers less than 0.2 of our ocean, but they contain 25% of the world´s marine fish species.
- There are three major types of coral reefs, Fringing reefs, Atoll reefs, and last but not least Barrier reefs.
- Fringing reefs are reefs that grow directly from a shore
- Atoll reefs are roughly circular/annular oceanic reef system´s surrounding by a large (and often deep) central lagoon
- Barrier reef are extensive linear complexes that parallel a shore and are separated from it by a lagoon
- Corals reef need water that is between sixty eight- eighty two, twenty- twenty eight
- Coral reefs need clear,clean,nutrient free water to thrive
- Corals typically grow only one-half an inch each year
- The Coral reef is extremely fragile, the lightest touch can destroy the living polys
- Roughly one-quater of coral reef, world-wide are already considered damayed beyond repair
- The coral reef have survived tens thousand years of natural change
- Coral bleaching occurs when stressful conditions occur
- Rising ocean temperature from global warming means, that events like catastropic nineteen niniety eight coral bleaching in the Great Barrier reef in Australia will become more common
- Fishing ,destruction, pollution, and massive species are taking a huge toil on the coral reef
- Coral reefs have a huge tourist attraction
- Various types of microscopic algae known as symbiodinis live inside the coral
- Reef-building corals may occur in a variety of growth forms, and there often is strong variation in coral shape even within a species
- In recent years scientists have discovered cold water coral reefs off the coast of Norway
- The skeletons of many coral colonies add up to build the structure of a coral reef
- Coral reefs are experiencing a rapid decline in ecosytem health
- Individual coral polys within a reef are typically very small usally half an inch
- In the so- called true stony corals, which compose of most tropical reefs, each polyp sits in a cup made of calcium
- For the coral reef ecosystem the sun is there source of energy
- An increase of greenhouse gases in the atmosphere also leads to more acidification of ocean water which can harm the corals and decrease the production of coral reefs
- Reefs usually develop in areas that have alot of wave action, because the waves bring in food, nutrients, and oxygen to the reefs
- For many coastal areas, coral reef also provide an important barrier against the worst ravages of storms
- The coral reefs organism are being used in treatments for diseases like cancer and HIV
- Chemical compounds extracted from corals, are used in medicine for ATDS, and other deadly dieases
- Reef building corals work together with microscopic algae, called Zooxanthellae
- The Zooxanthellae provides oxygen and food to the corals through photo-synthesis
- The coral reef provides protection to coastal communities from hurricanes and tornadoes
- The domiant organisms are known as framework builders, because they provide the Matrix for the growing reef
- The massive boulder and branching corals at the reef, form a basis of a coral community
- The variety of life that is supported by the Coral reef rivals, that is located in the tropical forest of the Amazon in New Guinea
- The reefs in Florida keys, holds at least 45 species of stony coral
- The longest barrier reef in the world, lies off the coast of Austraila
- Coral reefs are extremely vulnerable to warm water temperatures
- Pacific shallow are often dominated by the erect coral Pocillapora damicornis
- Several hundred species of colonial invertebrates can be found living on the undersides of platy corals
- When water temperatures rise, the algae living in the coral dies, creating large areas of dead bleached coral reefs
- Most of these organisms are colonial, and the slow process of precipitation, moves the living surface layer of the reef upward and seaward
