Warming seas, rising levels of atmospheric carbon dioxide and other factors such as over-fishing could wipe out the world's coral reefs by 2050 unless urgent action is taken to counteract these threats, environmental advocates warned on Wednesday. More than three quarters of all reefs are currently threatened, said advocates from U.S. government and non-governmental organizations while releasing the report entitled, "Reefs at Risk Revisited." Swift action must be taken to protect these...

An international scientific team has shown that strong links between the corals reefs of the south China sea, West Pacific and Coral Triangle hold the key to preserving fish and marine resources in the Asia-Pacific region. Research by Dr Johnathan Kool of the ARC Centre of Excellence for Coral Reef Studies and James Cook University, and his colleagues, has established that the richest marine region on Earth "“ the Coral Triangle between Indonesia, Malaysia and the Philippines "“...

More than a third of coral reef fish species are in jeopardy of local extinction from the impacts of climate change on coral reefs, a new scientific study has found. (Local extinction refers to the loss of species from individual locations, while they continue to persist elsewhere across their range.) A new predictive method developed by an international team of marine scientists has found that a third of reef fishes studied across the Indian Ocean are potentially vulnerable to increasing...

The more humanity acidifies and warms the world's oceans with carbon emissions, the harder we will have to work to save our coral reefs. That's the blunt message from a major new study by an international scientific team, which finds that ocean acidification and global warming will combine with local impacts like overfishing and nutrient runoff to weaken the world's coral reefs right when they are struggling to survive. Modeling by a team led by Dr Ken Anthony of the ARC Centre of Excellence...

Tropical Cyclone Yasi, a severe, top-category storm, ripped through Australia's northeast tourist coast Thursday, leveling houses and decimating crops as it hit land near the city of Cairns, gateway to Australia's Great Barrier Reef. The reef could face a slow recovery after recent flooding spewed toxic waste into its pristine waters. Marine experts say it is too early to assess the extent of the damage but the world's largest living organism, the sprawling coral structure, was very likely...

Researchers at Australia's leading coral reef research centre have developed a way to protect both coral reef fish - and the interests of fishers. In pioneering research carried out in Fiji in collaboration with the Wildlife Conservation Society (WCS), the CoECRS team has reported a new approach that enables communities to balance the need to protect the environment with the need to maintain local food supplies and incomes. Concern over the worldwide decline of coral reefs has prompted many...

Finding could help scientists monitor how corals adapt to global warming Young staghorn coral that fluoresce redder are less likely to settle and develop into coral polyps than their greener peers, University of Texas at Austin biologists have discovered. The finding may help scientists monitor how corals adapt to global warming because the less likely coral larvae are to settle, the more likely they will disperse from their reef of origin. "By simply looking at the color of a larval...

The key to preserving the extraordinary richness and beauty of the world's coral reefs through the coming period of fragmentation caused by climate change lies in a better understanding of how newborn coral larvae disperse across the oceans to settle and grow on new reefs. Research by scientists at the ARC Centre of Excellence for Coral Reef Studies is throwing new light on the survival and settlement rates of larvae from different coral species, as a basis for predicting how fast coral...

Wildlife Conservation Society confirms sea urchins destroy reef building algae in overfished sites on Kenya's coast An 18-year study of Kenya's coral reefs by the Wildlife Conservation Society and the University of California at Santa Cruz has found that overfished reef systems have more sea urchins"”organisms that in turn eat coral algae that build tropical reef systems. By contrast, reef systems closed to fishing have fewer sea urchins"”the result of predatory fish keeping...

The world's corals not only display stunning beauty and diversity "“ they also have rhythm, man. And that helps to keep them going through the lonely low-­"point of the night, when their partner robs them blind. That corals, among the simplest of Earth's creatures, have some curiously human-­"like attributes is emerging in a fresh set of revelations from by an international team of Australian and Israeli coral geneticists at...

Crown Of Thorns Starfish, Acanthaster planci
2013-11-11 10:54:41

The crown-of-thorns starfish (Acanthaster planci) is a species of starfish that is classified within the Acanthasteridae family. This species has a large range that extends from the Red Sea to the African coasts in the east and from the Indian Ocean to the western coasts of Central America. It prefers a habitat in coral reefs, which can be harmed if population numbers are too high. Damage occurs when filamentous algae covers bare skeletons of coral and the starfish move in to feed, stripping...

Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...

Knotted Fan Coral, (Melithaea ochracea), is a species of colonial soft coral that is found in tree-like fans on shallow reefs in the South China Sea between Taiwan and Indonesia, including Singapore and Malaysia. In Taiwan, it is the most widespread coral in its family Gorgonacea. It is found on the higher parts of reef fronts where its numerous small polyps can feed at water flow rates varying from 1.6 to 16 inches per second. This species usually grow to about 8 inches in length, with...

Leaf Plate Montipora, (Montipora capricornis), also known as Vase Coral, Cap Coral, or simply Montipora, is a species of stony coral found in the Indian and Pacific oceans. It is also found in reefs in the Red Sea. It usually inhabits the top half of the reef where photosynthesis can occur. It branches out from the foundation into an area with adequate sunlight. This species forms flat, plating colonies. The colonies expand by adding to their foundations and further spreading out....

Nephtheidae is a family of soft corals known as carnation corals, tree corals or colt soft corals. These corals are very striking and show a wide range of rich colors including red, pink, yellow and purple. These corals are mainly tree-like in that they branch out and have little knobs on the end of their rubbery branches. Another name given these animals are broccoli corals, due to the fact that their polyps retract in the daytime, giving them the resemblance of the vegetable. The polyps...
