Scientists said Thursday that lower-than-feared sea temperatures this summer gave a break to fragile coral reefs across the Caribbean and the central Gulf of Mexico that were damaged in recent years, the Associated Press reported. Many of the creatures that make up coral have had to expel the colorful algae they live with, creating a bleached color due to the unusually warm water in recent years. However, the coral itself will die and damage the environment where many fish and other marine...

Study sheds new light on threats to coral reproduction What's the point of setting up marine reserves to protect coral reefs from pollution, ship groundings and overfishing if climate change could cause far more damage? A study published this week in London in Proceedings of the Royal Society B provides the answer. For decades researchers have known that corals synchronize their release of eggs and sperm into the water but were unsure of how and why. Robert van Woesik, a biologist at the...

Discovery of shipping containers full of illegal coral in Oregon led to indictment WASHINGTON, Oct. 14 /PRNewswire-USNewswire/ -- Gunther Wenzek, a German national, pleaded guilty today before District Judge Anna J. Brown of the U.S. District Court for the District of Oregon to one count of smuggling coral into the United States at the port of Portland, Ore., the Justice Department announced. A grand jury in Portland indicted Wenzek in July 2008. Law enforcement officials arrested...

A conservation group said Thursday discovery of a type of coral off the shore of the town of Palm Beach, Fla. indicates it deserves protected habitat status. Palm Beach County Reef Rescue Director Ed Tichenor said the find may be the largest amount of Staghorn coral in Palm Beach County, the Palm Beach Post reported. This discovery is significant since the Town of Palm Beach is opposing federal critical habitat protection for this coral, said Connie Gasque, of Palm Beach who lead a dive...

NOAA scientists dove to new depths in the Northwestern Hawaiian Islands for the first time last month, venturing into never before seen territory. Divers from the National Oceanic and Atmospheric Administration vessel Hiialakai reached depths of 250 feet over the past month while studying reefs where no human had ever gone before. "We were seeing reefs that no human has ever laid eyes on before," Randall Kosaki, the research mission's lead scientist and diver, told the Associated Press. "We...

Australia's Great Barrier Reef is in danger of being ruined by climate change and coastal development, according to a report on Wednesday. According to the inaugural reef report issued by the Marine Park Authority, the reef has been hit by two different cycles of coral bleaching, and now algae and species infestation is becoming a serious problem that may threaten the reef's existence. "While populations of almost all marine species are intact and there are no records of extinctions, some...

Environmentalists are pushing for the protection of a large swath of coral reef off the Southeastern US coast. The underwater expanse of creatures and coral lies at the bottom of the Atlantic and spans about 23,000 square miles from North Carolina to Florida. But the collective is under threat from overfishing and energy prospects, and environmentalists are moving to push legislation that would protect the region. They claim that crab pots and bottom trawling for shrimp are the greatest...

Scientists in Australia announced on Thursday that a new genome-mapping project is underway that could help the Great Barrier Reef fight off the threats of climate change and toxic farm chemicals. The geneticists said that they are working on unlocking the secrets of the colorful acropora millepora coral, which has slowed in growing the last few years.  This coral is one of the main components of the northeastern tourist attraction. "This gene-mapping project has both practical and...

A new study shows that bleached corals bounce back to normal growth rates more quickly when they have clean water and plentiful sea life at their side The new research study led by scientists at Scripps Institution of Oceanography at UC San Diego suggests that by improving overall ocean health, corals are better able to recover from bleaching events, which occur when rising sea temperatures force corals to expel their symbiotic algae, known as zooxanthellae. Coral bleaching is a phenomenon...

An international team of researchers has studied the coralline algae fossils that lived on the last coral reefs of the Mediterranean Sea between 7.24 and 5.3 million years ago. Mediterranean algae and coral reefs began to resemble present day reefs following the isolation of the Mediterranean from the Indian Ocean and global cooling 15 and 20 million years ago respectively. The research team from the University of Granada (UGR) and the University of Modena and Reggio Emilia (Italia) show...

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...
