Take a stroll on a beach and you're likely to encounter plentiful evidence of life from the ocean amid the flotsam: stray clumps of seaweed, colorful seashells, even the occasional crustacean or jellyfish.
For a long time, scientists have wondered how a large number of species can live together while competing for a single, limiting resource. Why doesn't a single species that is better at competing for the resource crowd out all the others? According to new findings by Macquarie University, the an ...
It stops us from ageing, from looking like lobsters, from dying of skin cancer. ost sunscreens use chemical blockers to filter out ultraviolet rays and they’re incredibly difficult to remove from water – even after being treated.As a result, they’re now bleaching our precious coral reefs. 4
The red algae called Porphyra and its ancestors have thrived for millions of years in the harsh habitat of the intertidal zone—exposed to fluctuating temperatures, high UV radiation, severe salt stress, and desiccation.
Global climate change has increased water temperatures in the world's oceans, often causing mass coral bleaching and mortality, which harms not only corals, but also the vast ecosystems they support. Using innovative methods, researchers at Penn State University have identified a new species of ...
When it comes to marine animals, the charismatic kind like dolphins and whales get all the attention. But what about the weird-looking creatures that also live in the ocean’s depths? Sure they’re not beautiful, but they still play an role in marine ecosystems. Lucky for them, biologist and comed ...
London's Natural History Museum (NHM) has undergone a major revamp with a blue whale skeleton now forming the main exhibit as visitors come through the front door. The marine mammal replaces the much-loved Diplodocus dinosaur, "Dippy", which will soon head out on a tour of the UK.
The world's largest fish, a whale shark, recently got up close and personal with fishers in Ocean City, Maryland, nudging their boat for long enough that the crew captured a stunning video.
Researchers from the University of Hawai'i at Mānoa Department of Botany have discovered hundreds of potentially new species of fungi in the deep coral ecosystem in the 'Au'au channel off Maui. Mesophotic coral ecosystems (MCE) are generally found at depths between 130 to 500 feet and possess ab ...
Countries with these world heritage sites should aim to keep global temperature down, says UN agency.
New rules are urgently needed to protect life in the open seas, scientists have warned. A report to a UN ocean conference in New York points out that more than 60% of the ocean has no conservation rules as it’s outside national jurisdiction.
Scientists at University of Malaya, Malaysia, have found that the seagrass meadows in Johor harbor three times more juvenile fish than coral reefs. They also found that the dugong herds there prefer certain types of meadows over others.
Countries with responsibility over world heritage-listed coral reefs should adopt ambitious climate change targets, aiming to cut greenhouse gas emissions to levels that would keep global temperature increases to just 1.5C, the UN agency responsible for overseeing world heritage sites has said.
When you're a coral hanging out in the shallows, too much sunlight is a bad thing. Ultraviolet radiation can mess up the algae that live within coral bodies and provide them with much of their sustenance.
In 1998, the cruel heat of El Nino hit Seychelles hard. Sea surface temperatures rose around the Indian Ocean, bleaching 90% of coral reefs in the archipelago. Widespread flooding caused significant economic losses -- fishing and agriculture accounting for more than half of the total figure acco ...
University of Adelaide researchers have for the first time demonstrated that the ocean acidification expected in the future will reduce fish diversity significantly, with small 'weedy' species dominating marine environments.
Maybe the hardest part of conveying the scale and consequences of climate change is that transformation at the planetary scale can be hard to see. Carbon dioxide builds up invisibly in the atmosphere, seas inch inland year by year, and ecosystems continue to make their quiet shifts — big, slow c ...
United Nations Educational, Scientific and Cultural Organisation (UNESCO) just released its 'List of World Heritage in Danger', and it has one notable omission. The Great Barrier Reef. Australian experts have spoken out about the exclusion.
Coral reefs are economic mainstays and critical habitats. But something else makes them amazing: their otherworldly glow. Both shallow- and deep-water corals emit fluorescent light, but until now, scientists only understood why shallow-water corals light up. Now, reports Laura Castells for Natur ...
In 1988, Irish singer and songwriter Enya released a lead single titled "Orinoco Flow" from her second studio album, which went on to become an international hit, earn a Grammy Award nomination, and help launch her wildly successful career.Now a team of scientists have named a new species of fis ...
The Underwater Forest is a relic of an ancient past, a 60,000 year old cypress forest, lost for tens of thousands of years below the Gulf of Mexico. But in today's world, it is also something else: a vibrant marine ecosystem literally bursting with life.
In addition to the life on the surface of the Earth and in its oceans, ecosystems have evolved deep under us in a realm coined the "deep biosphere" which stretches several kilometers down into the bedrock. Down there, the conditions are harsh and life is forced to adjust to a lifestyle that we a ...
KITTS HUMMOCK, Del. — All along the shoreline, for as far as you can see, slick shells of horseshoe crabs glisten in the fading daylight. Listen closely, and you can hear their subtle clacking and the whisper of water over their carapaces.
Melbourne: The mass coral bleaching that devastated Australia's iconic Great Barrier Reef last year was caused by a 'perfect storm' of factors produced by unprecedented oceanographic conditions, scientists say.
What a sorry state of affairs that we’re putting a price tag on nature and biodiversity! The report did not attempt to put a price tag on nature. Ironically, its detractors did.What the authors of the report did was to calculate the value of a very narrow aspect of the full value of the Reef; i. ...
A healthy coral reef sounds like popcorn. Seriously: the hordes of snapping shrimp that fill their waters make create a constant crackling noise, something akin to crunching Pop Rocks or frying bacon
The peaceful and beautiful fish and other marine life displayed in household or public aquariums conceal a dark secret. Most of the roughly 1,800 species of tropical fish, as well as hundreds of invertebrate species, bought and sold globally to populate aquariums are caught using the destructive ...
The Indonesian government can't restore one of the country's best coral reefs until it strikes a compensation deal with the insurer of the cruise line that wrecked it, the deputy coordinating maritime minister said this week.
WASHINGTON — A mass bleaching of coral reefs worldwide is finally easing after three years, U.S. scientists announced Monday.
Deloitte Access Economics has valued the Great Barrier Reef at A$56 billion, with an economic contribution of A$6.4 billion per year. Yet this figure grossly underestimates the value of the reef, as it mainly focuses on tourism and the reef’s role as an Australian icon.

It's one of the tiniest organisms on Earth, but also one of the most abundant. And now, the microscopic marine bacteria called Prochlorococcus can add one more superlative to its list of attributes: It evolves new kinds of metabolites called lanthipeptides, more abundantly and rapidly than any o ...
We’ve all heard of chameleons, squid and octopus using pigments to blend in with their surroundings, but what about becoming completely invisible? To become actually see through, and appear as if you aren’t there, you need to either allow light to travel through you unimpeded, or bend light arou ...
JAKARTA — The Indonesian government can’t restore one of the country’s best coral reefs until it strikes a compensation deal with the insurer of the cruise line that wrecked it, the deputy coordinating maritime minister said this week.
"Somewhere between a quarter and a third of all marine species have some part of their lifecycle in a coral reef."So if we wipe out coral reefs, we are going to crash the ecologies of the oceans. It is that serious."
Much of the CO2 we emit through the burning of fossil fuels actually ends up in the ocean, making the water more acidic. Ocean acidification happens particularly fast in cold water. That spells trouble for creatures living in our northern waters – including cold water corals. How do they cope as ...
