Latest Coral reefs Stories
Australia’s Great Barrier Reef, the largest coral system in the world, so big that it can be seen from space, is one of the planet’s most remarkable natural wonders. But researchers from University of Queensland have now revealed this precious ecosystem is not faring well.
The Säcken reef in the Koster Fjord in Sweden is that country’s last remaining cold-water coral reef and it is under a distinct threat of extinction.
The ability of deep-sea corals to harbor a broad array of marine life, including commercially important fish species, make these habitat-forming organisms of immediate interest to conservationists, managers, and scientists.
A new study co-authored by the Wildlife Conservation Society identifies countries most vulnerable to declining coral reef fisheries from a food-security perspective while providing a framework to plan for alternative protein sources needed to replace declining fisheries.
While the single-celled algae that live inside corals typically play a vital role in keeping the reefs healthy, a new study suggests that an overabundance of the symbiotic organisms could have a negative effect on them.
Coral specialist Dr. Bert W. Hoeksema recently published a description of a new coral species that lives on the ceilings of caves in Indo-Pacific coral reefs.
A new study by the Wildlife Conservation Society and James Cook University says that coral reefs in Aceh, Indonesia are benefiting from a decidedly low-tech, traditional management system that dates back to the 17th century.
Marine diseases are killing coral populations all over the world, threatening the livelihoods of millions of people who depend on reefs for food and protection from storms.
According to new research from the Australian Institute of Marine Science (AIMS ), the Great Barrier Reef has lost half of its coral cover in the last 27 years.
When most people think of coral reefs, they are transported to temperate waters in a tropical locale. To even locate a coral ecosystem in the cold waters of the mid and north Atlantic would be a difficult endeavor. Or, at least, one would have thought.
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...
