Two eminent tropical marine scientists today urged Australians to get behind a plan by the Federal Government to transform nearly a million square kilometers of the Coral Sea into the world´s largest marine park. “The Coral Sea is one of a handful of places in the world where a very large oceanic no-take park can be created and monitored in a single national jurisdiction,” say Professors Terry Hughes and Bob Pressey of the ARC Centre of Excellence for Coral Reef Studies...

Some organisms already experiencing ocean acidification levels not predicted to be reached until 2100 A group of 19 scientists from five research organizations have conducted the broadest field study of ocean acidification to date using sensors developed at Scripps Institution of Oceanography, UC San Diego. The study, "High-Frequency Dynamics of Ocean pH: A Multi-Ecosystem Comparison," is reported in today's issue of the journal PLoS One. It is an important step toward understanding how...

Belize Protected Area Boosting Predatory Fish Populations
2011-12-23 05:27:43

Herbivorous fish needed for reef recovery still lagging A 14-year study by the Wildlife Conservation Society in an atoll reef lagoon in Glover's Reef, Belize has found that fishing closures there produce encouraging increases in populations of predatory fish species. However, such closures have resulted in only minimal increases in herbivorous fish, which feed on the algae that smother corals and inhibit reef recovery. The findings will help WCS researchers in their search for new...

Parrot Fish Are The Constant Gardeners Of The World's Reefs
2011-12-09 03:38:26

Australian scientists have urged greater consideration for the brilliantly-hued parrot fishes that tend and renew the world´s imperiled coral reefs. “Parrotfishes are the constant gardeners of the reef. They play a crucial role in keeping it healthy, suppressing weed, removing sediment and helping the corals to regrow after a setback,” explains Professor David Bellwood of the ARC Centre of Excellence for Coral Reef Studies and James Cook University. In a major new study...

Australian scientists have discovered that some tropical fish have a greater capacity to cope with rising sea temperatures than previously thought — by adjusting over several generations. The discovery, by researchers at the ARC Centre of Excellence for Coral Reef Studies, James Cook University and CSIRO sheds a ray of hope amid the rising concern over the future of coral reefs and their fish under the levels of global warming expected to occur by the end of the 21st century....

Observations at submarine springs found along the coast of Mexico's Yucatan Peninsula are giving scientists a preview of the possible fate of coral reef ecosystems in response to ocean acidification. The naturally low pH (a measure of acidity) in the water around the springs creates conditions similar to those that will result from the widespread acidification of surface waters that scientists expect to occur as the oceans absorb increasing amounts of carbon dioxide from the atmosphere....

Leaders Urged To Curb Climate Vulnerability
2011-11-28 05:54:49

Representatives of the world´s governments meeting in Durban this week have been advised by scientists that urgent action is needed to reduce the vulnerability of communities worldwide likely to be worst affected by the impacts of climate change. In a new scientific paper and book, leading marine researchers Dr Josh Cinner of the ARC Centre of Excellence for Coral Reef Studies (CoECRS) and James Cook University, and Tim McClanahan of the Wildlife Conservation Society (WCS) propose a...

2011-11-24 04:05:36

The elusive culprits that are killing countless coral reefs around the world can now be nabbed with technology normally used to diagnose human diseases, marine researchers say. Coral researchers and reef managers will be able to identify coral infections using a new method that allows them to classify specific diseases based on the presence of microbes. This could lead to more effective action to reduce the impact of disease on the world´s imperiled coral reefs. “Current...

Corals Can Sense What's Coming
2011-11-19 04:42:31

Australian scientists have thrown new light on the mechanism behind the mass death of corals worldwide as the Earth´s climate warms. Coral bleaching, one of the most devastating events affecting coral reefs around the planet, is triggered by rising water temperatures. It occurs when the corals and their symbiotic algae become heat-stressed, and the algae which feed the corals either die or are expelled by the coral. There have been seven major bleaching events globally in the past...

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 Reef
2013-04-20 15:49:21

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...

Foxface Rabbitfish, Siganus vulpinus

Image Credit: Dr. Wayne Meadows (NOAA)/Wikipedia The foxface rabbitfish is found in coral rich lagoons, and reefs in the coastal water of the Western Pacific. Around the western Philippines, Indonesia, New Guinea, the Great Barrier Reef, New Caledonia, Caroline Islands, and the Marshall Islands. It has also been sighted around Vanuatu, Nauru, Kiribati, and recently Tonga. Adults usually swim in pairs, but the juveniles have been known to form schools. The adult foxface rabbitfish is...

Barrier Reef Anemonefish, Amphiprion akindynos

The Barrier Reef Anemonefish (Amphiprion akindynos) is native to the marine lagoons and reefs in the Western Pacific Ocean.  It lives at a depth of around eighty-two feet in temperatures fluctuating between fifty degrees Fahrenheit to 89.6 degrees Fahrenheit. Its range includes northern New South Wales, the Loyalty Islands, Tonga, New Caledonia, Coral Sea, and the Great Barrier Reef. They are typically seen near or within the tentacles of their host anemones. They will inhabit anemones like...

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...
