Latest Coral reefs Stories
A new study by the Wildlife Conservation Society and James Cook University says that coral reefs in Aceh, Indonesia are benefiting from a decidedly low-tech, traditional management system that dates back to the 17th century.
Marine diseases are killing coral populations all over the world, threatening the livelihoods of millions of people who depend on reefs for food and protection from storms.
According to new research from the Australian Institute of Marine Science (AIMS ), the Great Barrier Reef has lost half of its coral cover in the last 27 years.
When most people think of coral reefs, they are transported to temperate waters in a tropical locale. To even locate a coral ecosystem in the cold waters of the mid and north Atlantic would be a difficult endeavor. Or, at least, one would have thought.
Australian researchers set out to study the effects of climate change and temperature dynamics around the Great Barrier Reef (GBR) and its critical protected areas. They were able to record and analyze major changes around the reef within the past 25 years.
For nearly 260 years -- since Carl Linnaeus developed his system of naming plants and animals -- researchers classified species based on visual attributes like color, shape and size.
Overfishing and nitrate pollution can destroy coral reefs by allowing an overgrowth of algae that brings with it unwanted pathogens, chokes off oxygen and disrupts helpful bacteria. These are the findings of a new study out of the Oregon State University, published recently in PLoS One.
Time may be running out on the world’s coral reefs which could be severely victimized by rising global temperatures and carbon dioxide levels
Ocean scientists have known for a long time that juvenile coral reef fishes use coastal seagrass and mangrove habitats as nurseries, before they move into the coral reefs as adults.
The crown-of-thorns starfish (Acanthaster planci) is a species of starfish that is classified within the Acanthasteridae family. This species has a large range that extends from the Red Sea to the African coasts in the east and from the Indian Ocean to the western coasts of Central America. It prefers a habitat in coral reefs, which can be harmed if population numbers are too high. Damage occurs when filamentous algae covers bare skeletons of coral and the starfish move in to feed, stripping...
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...
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...
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....
Nephtheidae is a family of soft corals known as carnation corals, tree corals or colt soft corals. These corals are very striking and show a wide range of rich colors including red, pink, yellow and purple. These corals are mainly tree-like in that they branch out and have little knobs on the end of their rubbery branches. Another name given these animals are broccoli corals, due to the fact that their polyps retract in the daytime, giving them the resemblance of the vegetable. The polyps...
