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.
The more humanity acidifies and warms the worldâ€™s oceans with carbon emissions, the harder we will have to work to save our coral reefs.
Tropical Cyclone Yasi, a severe, top-category storm, ripped through Australiaâ€™s northeast tourist coast Thursday, leveling houses and decimating crops as it hit land near the city of Cairns, gateway to Australiaâ€™s Great Barrier Reef.
Experts are calling for some reefs to be closed to oyster harvesting based on research that they claim has revealed that the global population of the mollusk species is declining rapidly.

The key to preserving the extraordinary richness and beauty of the worldâ€™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.
Wildlife Conservation Society confirms sea urchins destroy reef building algae in overfished sites on Kenya's coast.
Officials at the National Oceanic and Atmospheric Administration (NOAA) are vowing to protect newly located coral reefs found in a 12 mile span off the southwestern coast of Puerto Rico, hoping that their discovery could lead to the revitalization of the area's coral ecosystem.
The Edge Coral Reefs project announced this week that it has identified 10 of the most at-risk coral species for protection.
An expert said Wednesday that Australia's spectacular Great Barrier Reef is under threat from massive floods swamping the country's northeast, which are pouring harmful debris and sediment into the sea.
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...
Chalice Corals, are a family of stony corals in the Pectiniidae family. Members of this family are mostly colonial but at least one species, Echinomorpha nishihirai, is solitary. These corals are endemic to the Indian and Pacific oceans. Pectiniids have a number of different forms but are basically streamlined and smooth. Polyps are large and brightly colored and resemble those of members of the Mussidae family of corals. The polyps are only extended at night. Tentacles are translucent,...
Siderastreidae is a family of colonial, reef building stony corals. Members of this family include symbiotic algae in their tissues which help provide their energy requirements. The World Register of Marine Species lists 7 genera within this family: Anomastraea, Coscinaraea, Craterastrea, Horastrea, Psammocora, Pseudosiderastrea, and Siderastrea. Corals in this family vary in form and include massive, thickly encrusting, columnar, and irregular forms. Corallites are linked by flowing...
Horn corals, known as Rugosa or Tetracoralla, are an extinct order of coral that were abundant during the Middle Ordovician to Late Permian stages. They were known as horn corals because of a unique horn-shaped chamber with a wrinkled (rugose) wall. These mostly solitary corals often reached lengths of nearly 40 inches. However, some species could form large colonies. Rugose corals have a skeleton made up of calcite that is often fossilized. Like modern corals, rugose corals were...
Tabulata is a family of extinct tabulate corals. These corals lived entirely during the Paleozoic era, being found from the Ordovician to the Permian stages. There are about 300 known genera of tabulate corals, of which Aulopora, Favosites, Halysites, Heliolites, Pleurodictyum, Sarcinula and Syringopora are the most common in the fossil record. These corals were mostly found in the shallow waters of the Silurian and Devonian, after which, they became much less common. They became extinct...
