The main characteristics of coral reefs

Corals and coral reefs corals - plants or animals corals belong to the animal kingdom, and are members of the same group of animals as jellyfish and sea anemones (phylum: cnidaria) the actual coral animal or “polyp” is soft bodied, with tentacles like a sea anemone the main difference is that corals secrete an external calcium carbonate. The state of hawaii consists of eight larger islands (seven of which are populated), also called the main hawaiian islands, and 124 small, uninhabited islands, reefs and shoals, the northwestern hawaiian islands, where the majority of the hawaiian coral reef, about 70 percent of it, is located. Coral reefs support a great diversity of organisms and are a complex ecosystem with a strong linkage between planktonic-nektonic and benthic communities that influence the water chemistry and one another.

Coral reef coral reef research paper investigates the life and physical characteristics of this marine life coral is the common collective name for a large class of marine invertebrate polyps with six or eight tentacles the polyps secrete calcium carbonate which forms an exoskeleton into which the polyp withdraws for protection from predators. All coral reefs have distinctive horizontal and vertical zones created by differences in depth, wave action, current movement, light, temperature and sediment along different parts of the reefalthough the exact characteristics of each zone may vary slightly depending on the location and type of reef, all reefs have a fore reef, or seaward. Distribution and conditions of coral reef formation: corals have built a thick stratum of the earth’s crust, they have coral reefs in the caribbean seas and in the indo-pacific region from east coast of africa to the north-eastern coast of australia which is known as the great barrier reef. Coral polyps are tiny, soft-bodied organisms related to sea anemones and jellyfish at their base is a hard, protective limestone skeleton called a calicle, which forms the structure of coral reefs.

Coral reefs are the most diverse of all marine ecosystems they teem with life, with perhaps one quarter of all ocean species depending on reefs for food and shelter this is a remarkable statistic when you consider that reefs cover just a tiny fraction (less than one percent) of the earth’s surface and less than two percent of the ocean bottom. Main characteristics of the coral reef systems studied, including region and code (see fig 1), estimated length of the reefs (where available), the distance from the shore to each reef, how the reef can be accessed, whether the region is a marine protected area (mpa), whether the region is a recreational dive site, and descriptions of the. Coral reefs are one of the most diverse and productive ecosystems on the planet globally, corals are declining and algae are increasing due to anthropogenic activities while most research and conservation efforts focus on the proliferation of macroalgae, in fact most algae on coral reefs are turf.

Coral reefs are rich in life, but are dying around the world this page explores some of the problems in further detail. Coral reefs are formed by large colonies of ant-sized organisms called corals coral reefs have existed for more then 200 million years coral reefs are some of the most diverse ecosystems in the world, housing tens of thousands of marine species. Coral reefs are the most diverse of all marine ecosystems they teem with life, with perhaps one-quarter of all ocean species depending on reefs for food and shelter this is a remarkable statistic when you consider that reefs cover just a tiny fraction (less than one percent) of the earth’s. Coral reefs are often called the rainforests of the sea, both due to the vast amount of species they harbour, and to the high productivity they yield aside from the hundreds of species of coral, reefs support extraordinary biodiversity and are home to a multitude of different types of fish, invertebrates and sea mammals covering less than one.

the main characteristics of coral reefs Coral reefs are home to thousands of different species of plants,fishes, and other types of animals, but the coral reef biome is dominated by just a few main groups these dominant groups include one type of unusual animals called the stony or scleractinian corals, and a type of marine algae called crustose coralline red algae.

Coral reefs are home to an abundant variety of living creatures—fish, turtles, sharks, eels, crabs, shrimps, urchins, sponges, and algae to name a few in the pacific islands, coral reefs have some of the highest biodiversity in the world for example, guam hosts over 3,500 species of plants and animals, including 200 different types of corals.

The characteristics of a coral reef biome will depend on if it is a hard or soft coral reef with the hard coral reef you will find those limestone skeletons being left behind from brain coral and elk horn coral with a soft coral. Parrotfishes share some characteristics with wrasses family: labridae habitat coral reefs range coral reefs worldwide natural history generally brightly colored, about 60 species of parrotfishes swim in coral reefs around the world they have fused teeth that form beaklike plates, giving them a parrotlike appearance they have large thick.

Temperature-coral reefs thrive in water temperatures of 77° to 84° fahrenheit ( 25° and 29° celsius ) certain corals have evolved to survive outside this temperature range such as ahermatypic corals (see adaptations and relationships) the types of corals you find in the great barrier reef are hermatypic corals- meaning they contain zooxanthellae. What is a coral reef coral reefs are one of the most biologically diverse ecosystems on earth, rivaled only by tropical rain forests they are made up not only of hard and soft corals, but also sponges, crustaceans, mollusks, fish, sea. Threats to coral reefs despite the importance of coral reefs, these wildlife habitats are imperiled throughout the world a recent report estimated that 75 percent of remaining coral reefs are currently threatened, and many have already been lost even some of the most remote and pristine reefs are losing species.

Coral reefs coral reefs are the most eye-catching ecosystems in the ocean what many do not know is that the majestic, colorful coral not only attracts the human eye, but some of the deadliest predators in the ocean. The coral reefs attract algae, which aid coral by producing food in turn, the algae receive shelter by the coral living corals and algae form closest to the water's surface on top of older, deceased corals. Physical map location of coral reefs 1:50 000 000 500km 1500km 1000km legend presence of coral reefs a physical map is a interpretation of natural location, depicting where a feature is on the earth’s surface this physical map displays the location of coral reefs, the red marks indicating the presence of the ecosystem as observable. Coral reefs have existed for some 100 million years, but most living reefs originated or renewed their growth at the end of the pleistocene (about 10,000 years ago), when sea levels rose in response to melting continental ice sheets.
