Half a century after the last earth-shattering atomic blast shook the Pacific atoll of Bikini, the corals are flourishing again. Some coral species, however, appear to be locally extinct.

While rabbits continue to ravage Australia’s native landscapes, rabbit fish may help save large areas of the Great Barrier Reef from destruction.

Biologist Pablo Cermeño Villanueva defended his PhD thesis at the University of the Basque Country (UPV/EHU), providing a tool to determine the age of anchovies with greater accuracy on a monthly or even weekly basis, thus enabling studies of the earliest phases of life to be undertaken.

Scientists have discovered Antarctic krill (Euphausia superba) living and feeding down to depths of 3000 metres in the waters around the Antarctic Peninsula. Until now this shrimp-like crustacean was thought to live only in the upper ocean.

Scientists say they have taken an array of new marine species from the seabed off eastern Antarctica. They are warning, though, that climate change could soon make extinct many of the strange creatures they have just discovered. From Sydney, Phil Mercer reports.

As oceans warm and become more acidic, ocean creatures are undergoing severe stress and entire food webs are at risk, according to scientists at a press briefing this morning at the annual meeting of the American Association for the Advancement of Science in Boston.

One of the most significant questions facing marine ecologists today, is just how much of an impact global variations in the environment are having on the dispersal of larval and juvenile marine species from open oceans to coral reefs.

In an article published in the January 16 issue of PLoS ONE, Joan B. Company and colleagues at the Institut de Ciencies del Mar (CSIC) in Spain describe a mechanism of interaction across ecosystems showing how a climate-driven phenomenon originated in shelf environments controls the biological processes of a deep-sea living resource.

When David Jones, a fisheries oceanographer at the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) located at the University of Miami’s Rosenstiel School, set out to design a better light trap to collect young reef fishes, he never imagined his invention would contribute to the discovery of a new species.

Over 50 scientists of the ARC Centre of Excellence for Coral Reef Studies today declared the following statements unanimously:

A ghostly, mutant ratfish caught off Whidbey Island in Washington state is the only completely albino fish ever seen by both the curator of the University of Washington's 7.2 million-specimen fish collection and a fish and wildlife biologist with more than 20 years of sampling fish in Puget Sound.

Researchers report the most complete list so far of proteins present in a virus that causes severe shrimp mortality and significant economic losses to shrimp cultivation worldwide.
