The salt and chemicals in the brine left over from desalination can threaten local marine ecosystems

A prized delicacy in Japan, where poisonous varieties are prepared by skilled chefs, pufferfish are giving spicy crayfish a run for their money in Beijing

Underwater robot has delivered over 100k baby corals in attempt to restore part of the Great Barrier Reef

Increasing ship traffic, sonar and seismic air gun blasts now planned for offshore drilling may be disrupting migration, reproduction and even the chatter of the seas’ creatures.

An analysis concluded that Earth’s oceans are heating up 40 percent faster on average than a United Nations panel estimated five years ago, a finding with dire implications for climate change.

The dead sperm whale, which washed ashore in Indonesia, had ingested nearly 6kg of plastic waste.

Plastic was found in the gut of every single sea turtle examined in a new study, casting fresh light on the scale of plastic pollution in the world's oceans. The research, published in the journal Global Change Biology, examined more than 100 sea turtles of all seven species, across the Atlantic, Pacific and Mediterranean.

Some fish parasites are on the rise, bringing with them risks to human health and fisheries-based economies. Now researchers have a new way to track their numbers—by digging into old records and museum samples. Recent years have seen alarming outbreaks of disease in fish and other marine species, including one that caused a massive die-off of sea stars in the northeast Pacific starting in 2013. But it has not been clear whether this uptick in illnesses was due to an actual increase in the number of pathogens...

Asia is growing. Literally. From Malaysia to Dubai, luxury developments are rising on artificial islands and coastlines. Everybody wins – except the local sea life and the fishermen who depend on it

Every year, more than 400,000 crabs are bled for the miraculous medical substance that flows in their veins—now pharmaceutical companies are finally committing to an alternative that doesn't harm animals.

Planet or Plastic? : Even one of the most remote places on Earth couldn't hide from the scourge of plastic trash.

Who owns Maine’s most important seaweed?

Seeing how microbes snatch new genetic material from their environment could help in the fight against antibiotic resistance.

Humans have spent more than 10 centuries emptying the ocean of some of its most extraordinary animals. Today, a coalition of scientists and fishermen are trying to turn the tide – and learning that conservation is much harder than destruction

Coral harming chemicals oxybenzone and octinoxate.are to blame for the ban, which was just signed by governor. The ban won't take effect until 2021.

How a piece of trash can travel from land to Henderson Island, an uninhabited, remote island in the middle of the South Pacific Ocean.

Recent paper makes a big claim, but other scientists are unconvinced.

Florida has an algae problem, and it’s big. This year, an overgrowth in the waters off the state’s southwestern coast is killing wildlife and making some beaches noxious. The toxic algal bloom, known as a red tide, is not unusual. They appear off the state’s coast almost every year. But this one, still going strong after roughly nine months, is the longest since 2006, when blooms that originated in 2004 finally abated after 17 months.

Half of the Great Barrier Reef has been bleached to death since 2016. Mass coral bleaching, a global problem triggered by climate change, occurs when unnaturally hot ocean water destroys a reef’s colorful algae, leaving the coral to starve. The Great Barrier Reef illustrates how extensive the damage can be: Thirty percent of the coral perished in 2016, another 20 percent in 2017. The effect is akin to a forest after a devastating fire.

Fossil enthusiast Philip Mullaly was walking along the beach in Victoria Australia when he saw it: a glint in a boulder with quarter of a tooth exposed. "I was immediately excited, it was just perfect and I knew it was an important find that needed to be shared with people," Mullaly explained.

If you think Charleston, South Carolina, has plenty of history within its pre-Colonial grounds, just look at what’s been hiding 160 miles off the city’s coast for thousands of years: a giant deep-sea coral reef system. The chief scientist who helped make the discovery called it unbelievable.

Nudibranchs may look cute, squishy and defenseless ... but watch out. These brightly-colored sea slugs aren't above stealing weapons from their prey.

An underwater drone that can keep watch on reef health and accurately identify and inject the devastating crown-of-thorns starfish is ready to be put to the test on the Great Barrier Reef, as a result of a collaboration between QUT, Google and the Great Barrier Reef Foundation.

New study: Ingesting even a single piece of plastic exposes sea turtles to a 20% chance of death.

Did the octopus evolve its unique intelligence by playing fast and free with the genetic code? Elizabeth Finkel investigates.

A trial is underway to restore damaged coral on the Great Barrier Reef using electricity. The reef has been severely assaulted in recent years by cyclones and back-to-back heatwaves. Nathan Cook at conservation group Reef Ecologic and his colleagues are attempting to regrow surviving coral fragments on steel frames. The frames are placed on damaged parts of the reef and stimulated with electricity to accelerate the coral’s growth (see video).

New technology will use facial recognition to build individual medical records for millions of fish.

For the first time, a species of fish has demonstrated evidence of possible self-awareness by passing the famous mirror test.

The planet’s coral reefs are in trouble. Thanks to warming and acidifying oceans, the animals that make up coral reefs are dying, turning the reefs themselves into algae-covered ghost towns. This represents a loss of habitat for numerous nearby creatures, many of which evolved to only live in the reefs. So the deaths of the corals can lead to the deaths of many other species. From monitoring the reefs by listening to them to local action and working to understand the dynamics of coral illness, scientists and conservationists...

Noise from ships and boats are causing dolphins to make their calls less complex, according to a new study.

Bloomberg Philanthropies to launch major grant for coastal communities to improve the health of oceans

With a growing world population and climate challenges that are causing agricultural areas to shrink, many are wondering where sustainable food will come from in the future. A professor of gastrophysics from the Department of Food Science at the University of Copenhagen and a chef offer a suggestion in a new research article: The cephalopod population (including squid, octopus and cuttlefish) in the oceans is growing and growing – let’s get better at cooking them so that many more people will want to eat them!

As he was working with corals at the Mote Marine Laboratory in Florida, Dr. David Vaughan accidentally discovered a groundbreaking coral reef recovery method that makes corals grow by 40 times faster than usual.

Harry Brower Sr. was lying in a hospital bed in Anchorage, Alaska, close to death, when he was visited by a baby whale. Although Brower’s body remained in Anchorage, the young bowhead took him more than 1,000 kilometers north to Barrow (now Utqiaġvik), where Brower’s family lived. They traveled together through the town and past the indistinct edge where the tundra gives way to the Arctic Ocean.
