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...

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!

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

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

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.

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.

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

This week, we deployed System 001 in the Great Pacific Garbage Patch. In the upcoming months, we are hoping to confirm its plastic capturing efficiency and survivability; thus proving our technology. Read more in our latest update. Watch Project Manager Henk van Dalen explain the progress for System 001, a.k.a. Wilson in the video above.

At the Pacific Ocean's largest green sea turtle rookery, a crisis is unfolding, likely thanks to warming temperatures. Will this become a global problem?

Killer whales able to copy words such as “hello” and “bye bye” as well as sounds from other orcas, study shows

Did a 1970s CIA plot spark a boom in deep sea mining?

Starfish and crabs among animals piled ankle-deep along parts of the North Sea coast

Researchers introduced SoFi, a soft robotic fish that can be operated underwater with a souped up Super Nintendo controller.

Scientists have long been trying to figure out how exactly our ancestors evolved from fish to land vertebrates some 375 million years ago. Now a tiny, eyeless fish that walks and climbs up waterfalls could offer some clues... By Kaitlyn Tiffany.

Arctic people have been communicating with cetaceans for centuries. The rest of the world is finally listening in

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.

These sharks have a hidden life that's becoming a lot less hidden, thanks to a scientific expedition that was years in the making.

Who owns Maine’s most important seaweed?

On World Oceans Day, let's commit to preserving this vital ecosystem.

On the frontlines of extinction in the Gulf of California, where the vaquita faces its final days.

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

Five years after a mysterious virus wiped out millions of starfish off the western coast of North America, causing them to lose legs, dissolve into fleshy goo and taking various species to the brink of disappearance, scientists have announced a remarkable reversal.

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.

Fish are losing their sense of smell because of increasingly acidic oceans caused by rising levels of carbon dioxide (CO2) in the atmosphere, new research shows.

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.
