Coral reefs houses diverse community of species

O ften referred to as the “rainforests of the sea,” coral reefs support approximately 25 percent of all known marine speciesreefs provide homes for more than 4,000 species of fish, 700 species of coral, and thousands of other plants and animals the architects of coral reefs are hard corals. Although assessing coral species or genera composition is often informative, the extremely high diversity of coral reefs (the great barrier reef, australia has 450 known species of coral, for example) has led to various attempts to group species into ecologically meaningful categories. Diversity: refers to the variety of species within a given association, areas of high diversity are characterized by a great variety of species algae : a diverse group of photosynthetic organisms that lack roots, stems, leaves, and vascular tissues.

coral reefs houses diverse community of species Scientists have discovered that large areas of intact coral reef with extensive live coral cover, not disturbed by humans or climate change, harbor the greatest amount of genetic diversity with.

When you think of coral reefs, you probably think of a tropical locale with white sand beaches and warm waters which contain a colorful array of coral species, home to a diverse group of fish, algae, sponges and more. • coral reefs house between 600,000 and 9 million species • 25% of marine species rely on coral reefs at some point in their life cycle • 32 of the 34 phyla of metazoans live on reefs • 65% of marine fishes live in reefs. When coral reefs turn deathly white as ocean temperatures spike, the kaleidoscope of marine life surrounding them dims as well, becoming more functionally monochromatic and less ecologically diverse, according to researchers who studied a section of the great barrier reef before, during, and after a catastrophic coral bleaching event in 2016.

Ecological impacts of marine invasive algae include changes in community structure in the invaded community and reduced abundance, diversity, feeding, performance, and function of native species invasive algae can quickly invade and take over coral-dominated habitats. Changes in coral community composition can occur when more susceptible species are killed by bleaching events changes in coral communities also affect the species that depend on them, such as the fish and invertebrates that rely on live coral for food, shelter, or recruitment habitat. Among the diverse species that depend on deep-sea corals are ones that are commercially important to humans—including shrimp, crabs, groupers, rockfish, and snappers off alaska’s aleutian islands , 85 percent of commercially important fish species are associated with deep-sea coral habitats. A previously overlooked predator— a thumbnail-sized snail—could be increasing the pressure on coral reefs already weakened by the effects of overfishing, rising ocean temperatures, pollution and other threats the snail attacks a key coral species that may offer the last hope for bringing back degraded pacific reefs.

Among the most diverse and biologically complex ecosystems on earth, coral reefs protect island communities from coastal erosion and storm damage, provide habitat to numerous species, and support important tourism and recreational industries. “coral reefs are home to a significant diversity of marine life, provide valuable economic and environmental services to millions of people, buffer shorelines from erosion and waves and can serve as a resource for the development of new medicines,” said thierry work, a usgs scientist and the lead author of the study. Coral reefs create homes to up to 9 million species single-celled algae enable coral polyps to build these reefs coral reefs are home to ¼ of all marine species, yet they cover less than 1/10th of the surface of the world’s oceans coral polyps enable this diversity to exist by building a 3.

Climate induced coral bleaching events are the greatest threat to coral reefs as shown here, there is extensive bleaching of hard and soft corals at moore reef following sustained heat stress in. The coral bleaching events that have devastated the great barrier reef in recent years have also taken their toll on the region’s fish population, according to a new study while rising. Coral reefs are the most diverse habitats on the planet reefs occur in less than 1 percent of the ocean, yet are home to nearly one-quarter of all ocean speciesthese ancient structures make a perfect home for millions of species of fish, crabs, clams, starfish, squid, sponges, lobsters, seahorses, sea turtles, and more.

  • Coral reefs support very diverse fish communities, ranging from around 500 to 700 species altogether on the reefs in the caribbean and central pacific, to 3000.
  • Coral reefs of the northern caribbean have undergone widespread change over the past century, driven by coastal development, pollution, over-fishing, the introduction of invasive species, and.
  • The northwest hawaiian island coral reefs provide an example of the diversity of life associated with shallow-water reef ecosystems this area supports more than 7,000 species of fishes, invertebrates, plants, sea turtles, birds, and marine mammals.

The species is an important reef-building coral in the caribbean, and its symbiosis with micro-algae has been studied extensively image by robin t smith banner image of fish above a coral reef. Coral reefs are home to millions of species hidden beneath the ocean waters, coral reefs teem with life fish, corals, lobsters, clams, seahorses, sponges, and sea turtles are only a few of the thousands of creatures that rely on reefs for their survival. Coral reefs are among the most diverse communities on this planet, often described as rainforests of the sea reefs occur in clear, shallow waters throughout tropical regions across the globe formed by the calcium carbonate skeletons, the backbone of the reef is built by tiny coral animals that make up large coral colonies.
