By Yereth Rosen ANCHORAGE, Alaska (Reuters) - Newly discovered gardens of colorful corals, which bloom about 1,000 feet (305 meters) underwater off Alaska's Aleutian Islands and in the Gulf of Alaska, will get special protection starting Friday.
Leopards may not be able to change their spots, but corals can change their skeletons, building them out of different minerals depending on the chemical composition of the seawater around them.
In the azure waters of Florida's remote Dry Tortugas National Park, corals have been toppled by hurricanes and blighted by disease and a phenomenon known as bleaching.
Caribbean Sea temperatures have reached their annual high two months ahead of schedule - a sign coral reefs may suffer the same widespread damage as last year, scientists said Monday.
By Alister Doyle, Environment Correspondent OSLO (Reuters) - Less than 2 percent of the world's tropical coral reefs are properly protected from illegal fishing, mining or pollution despite government promises of wider safeguards, an international study showed on Thursday.
Warmer sea temperatures could worsen the widespread destruction of coral reefs that hit the Caribbean in 2005, scientists fear.
Deadly diseases are attacking coral reefs across the Caribbean Sea after a massive surge of coral bleaching last summer, a two-pronged assault that scientists say is one of the worst threats to the region's fragile undersea gardens.
Scientists have been working hard to understand the environmental conditions causing the widespread coral bleaching in Australia's Great Barrier Reef and it's subsequent effects on the global ecology. This work is being aided by NASA satellites which provide scientists with near-real-time sea surface temperature and ocean color data.
A one-two punch of bleaching from record hot water followed by disease has killed ancient and delicate coral in the biggest loss of reefs scientists have ever seen in Caribbean waters.
Rising sea temperatures caused by global warming could kill off the Indian Ocean's coral reefs in the next 50 years, threatening vital marine life, a marine researcher said on Wednesday.
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...
Octopus Coral, (Galaxea fascicularis), also known as Fluorescence Grass Coral, Galaxy Coral. Star Coral, Crystal Coral, Brittle Coral and Starburst Coral, is a species of colonial stony coral commonly found on reef slopes in the Indian and Pacific ocean regions, as well as the Red Sea and the Gulf of Aden. It is most commonly found where wave action is weak, usually at a depth of 79 inches to 49 feet below sea level. It is a common coral species among reef aquarium enthusiasts. This coral...
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...
Leaf Plate Montipora, (Montipora capricornis), also known as Vase Coral, Cap Coral, or simply Montipora, is a species of stony coral found in the Indian and Pacific oceans. It is also found in reefs in the Red Sea. It usually inhabits the top half of the reef where photosynthesis can occur. It branches out from the foundation into an area with adequate sunlight. This species forms flat, plating colonies. The colonies expand by adding to their foundations and further spreading out....
