New research highlights the role of diversity in the healthy functioning of coral reef ecosystems and shows that guard-crab species and size classes offer different kinds of effective protection against various threats to coral reefs.
An expedition from the Hebrew University of Jerusalem and the Carnegie Institute of Science has measured a roughly 40% reduction in the rate of calcium carbonate deposited in Australia’s Great Barrier Reef in the last 35 years.
A team of researchers working on a Carnegie expedition in Australia’s Great Barrier Reef has documented that coral growth rates have plummeted 40 percent since the mid-1970s. The scientists suggest that ocean acidification may be playing an important role in this perilous slowdown.
New research has found that the Great Barrier Reef, as a whole, is a remarkably effective wave absorber, despite large gaps between the reefs.
One of Australia’s leading coral reef ecologists fears that reef biodiversity may not provide the level of insurance for ecosystem survival that we once thought.
Sharks in no-fishing zones in the Great Barrier Reef (GBR) Marine Park are more abundant when the coral is healthy
Pacific corals and fish can both smell a bad neighborhood, and use that ability to avoid settling in damaged reefs.
New research indicates older species of coral have more of what it takes to survive a warming and increasingly polluted climate, according to biologists from the University of Texas at Arlington and the University of Puerto Rico – Mayagüez.
The hard corals primarily responsible for the construction of coral reefs around the world have attracted the attention of taxonomists for hundreds of years.

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...
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...
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...
