The Wildlife Conservation Society today released initial field observations that indicate that a dramatic rise in the surface temperature in Indonesian waters has resulted in a large-scale bleaching event that has devastated coral populations.
Scientists in Australia have found a cluster of dazzling shallow-water corals that could help with the production of possible cancer-fighting drugs and may help to understand global warming.
The growing amount of human noise pollution in the ocean could lead fish away from good habitat and off to their death.
University of Guam Marine Lab associate professor, Alexander Kerr, is senior author of a paper on the evolutionary origins of coral sex published in the Proceedings of the Royal Society B.
An Australian scientist has discovered what could be the worldâ€™s rarest coral in the remote North Pacific Ocean.
Scientists say that a species of coral in the Red Sea could stop growing by 2070 if current warming trends continue.
Australian scientists have found strange prehistoric sea life several hundreds of feet below the Great Barrier Reef, during a first-of-its-kind mission to document species under threat from warming of the worldâ€™s oceans.
Improving the quality of local water increases the resistance of coral reefs to global climate change.
At first glance it may seem like a good idea to be a fish living the quiet life on a small and isolated reef.
International law failing to protect coral reefs and tropical fish.
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...
