Wreckage on the ocean floor near a Japanese island must be from a fighter-bomber that crashed in 1945 with an American pilot who is still listed as missing in action, according to a World War II researcher who recently visited ...

Live fast, die young: Study shows tiny fishes fuel coral reefs

Scientists have long sought to understand how coral reefs support such an abundance of fish life despite their location in nutrient-poor waters. According to a new study published May 23 in the journal Science, an unlikely ...

Conservation goals compete at the expense of biodiversity

With an ever-growing list of threats facing biodiversity on multiple scales, conservationists struggle to determine which to address. A common reaction is to prioritize their efforts on threats to individual species or management ...

New study finds distinct microbes living next to corals

Symbiotic algae living inside corals provide those animals with their vibrant color, as well as many of the nutrients they need to survive. That algae, and other microbes within the bodies of corals, have been extensively ...

Tiger sharks revealed as lazy predators

One of the ocean's most feared predators – the tiger shark—has been revealed as a relaxed and sometimes lazy hunter by scientists studying their behaviour.

Coral reef

Coral reefs are aragonite structures produced by living organisms, found in marine waters containing few nutrients. In most reefs, the predominant organisms are stony corals, colonial cnidarians that secrete an exoskeleton of calcium carbonate. The accumulation of skeletal material, broken and piled up by wave action and bioeroders, produces a calcareous formation that supports the living corals and a great variety of other animal and plant life.

Coral reefs most commonly live in tropical waters, but deep water and cold water corals exist on a much smaller scale.

Globally, coral reefs are under threat from climate change, ocean acidification, overuse of reef resources, and harmful land-use practices. High nutrient levels such as those found in runoff from agricultural areas can harm reefs by encouraging excess algae growth.
