Latest Reef Stories
National Oceanic and Atmospheric Administration (NOAA) experts are concerned that there could be massive coral bleaching in the Caribbean this year--perhaps on par with the bleaching that damaged over 80% of the basin region's coral five years ago.
Healthy reefs with more corals and fish generate predictably greater levels of noise, according to researchers working in Panama. This has important implications for understanding the behaviour of young fish, and provides an exciting new approach for monitoring environmental health by listening to reefs.
MOBILE, Ala., Sept. 15 /PRNewswire/ -- A coalition of leading environmental organizations has unveiled plans for a major Gulf restoration project with the launch of 100-1000: Restore Coastal Alabama Partnership (www.100-1000.org).
A team of researchers from Australian and New Zealand have discovered an ancient, massive coral reef in the Pacific Ocean, making it the southernmost reef discovered to date.
Xestospongia muta, better known as the giant barrel sponge, is now the most dominant life form in the coral reefs of the Caribbean and the Florida Keys.
Chemists discover how oysters bond together to form massive reef complexes.
Tiny corals face shocking losses when first they settle on reefs, making the full complexity and wonder of the mature coral reef all the more remarkable.
Next month, scientists plan to monitor corals in the Northwestern Hawaiian Islands for signs of bleaching.
Rising ocean temperatures in waters off the northwestern coast of Indonesia are killing off coral at one of the fastest rates ever recorded.
Australian researchers are a step closer to understanding the rapid decline of our coral reefs, thanks to a breakthrough study linking coral immunity with its susceptibility to bleaching and disease.
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...
