A swarm of Chaoborus edulis flies over Lake Malawi

Why Don’t Insects Live in the Ocean? Scientists Just Ruled Out One Possible Explanation Thanks to Deep-Diving Fly Larvae

Researchers thought that insects might not live there because their respiratory systems would implode from water pressure. But certain fly larvae in East Africa make daily trips toward the bottom of Lake Malawi with the help of strong air sacs that contain a stretchy protein

Researchers made the discovery while studying the California two-spot octopus.

Why Are Some Octopuses So Smart? The Answer Might Lie in a Never-Before-Seen Mutation That Helps Them Accurately Build Proteins

Scientists discovered a strange feature in certain octopuses’ ribosomal RNA, molecules that create a 3D scaffold for cellular protein factories. It was found only in shallow-water creatures that have expanded nervous systems and can do complex behaviors

These Coral Reefs Off West Africa Were Long Presumed Dead. Scientists Just Found Them Alive and Teeming With Life

Fish surveys in the 1960s detected what experts thought was a dead coral reef barrier off the country of Benin. Decades later, researchers set off in small fishing boats to investigate it using sonar mapping, underwater drone surveys and stationary video recorders

A harbor porpoise surfaces near the Golden Gate Bridge.

Marine Biologists Solved a Wildlife Mystery From the Walkway of the Golden Gate Bridge: How the Harbor Porpoise Mates

The dolphin-like marine mammals returned to San Francisco Bay in 2008 after a decades-long absence from the area. Scientists took the rare opportunity to closely observe their behavior, and what they uncovered might help at-risk porpoise populations

A blue whale has been gathering food deep within the water column and reaches the surface with its throat pleats still distended, forming an enormous pouch. Within a few moments the whale will right itself up, expell the water, swallow the food, take several breaths and dive again.

The Global Web of Subsea Cables That Connects the World Can Now Detect Whales—Even When They’re Silent

A diving whale revealed how existing technology makes it possible to monitor cetaceans swimming quietly across the seabed

The global bodyboard market is estimated to reach $623.6 million by 2035, up from $296.3 million in 2024.

How the Boogie Board Became One of Summer’s Most Popular Toys

Fifty-five years ago, surfer Tom Morey cut a piece of polyethylene foam with a carving knife and created a wave-riding board with a low barrier of entry

Amphorae from the Macquarie University history museum

Off the Coast of Sicily, Divers Discovered a Roman-Era Shipwreck With Hundreds of Amphorae, Ancient Jars Frequently Used to Hold Wine

The site could offer fresh insights into Mediterranean trade routes more than 2,000 years ago

Researchers involved in the study collect samples at Blood Falls.

Why Does Antarctica’s Blood Falls Spew Ruby Red Water? Microbes Offer New Clues About the Geologic Feature’s Ancient Origins

The falls contain saltwater rich with iron, which oxidizes and turns red when exposed to air. A new study provides further evidence that the brine probably comes from ocean water trapped when flood waters retreated millions of years ago

A surfer rides a wave during a competition in the Ngor district of Dakar, Senegal, the most westerly point of mainland Africa.

Big Waves Meet Biodiversity: Why Surfing Paradises Could Offer a Key Opportunity for Marine Conservation

A recent mapping study examines places in northwestern Africa where coastal ecosystems overlap with surf breaks, highlighting areas that could support recreation, the environment and local economies, if protected

A digital illustration of typical prokaryotes—cells that do not contain a nucleus. Bacteria and archaea are the two kinds of prokaryotes on Earth, and their ancestors were the first organisms to evolve.

A New Study Points to Two Origins of Life on Earth by Tracing Early Chemical Reactions in Single-Celled Organisms

The work challenges the assumption that all life descended from one free-living cell. Instead, it suggests that two microbial lineages, the bacteria and archaea, evolved independently from a primordial, nonliving ancestor

This illustration shows an ichthyosaur biting a pterosaur, with a pliosaur preparing to attack from below.

Rare Fossil Reveals a Three-Tier Food Chain Frozen in Time: a Pterosaur Eaten by an Ichthyosaur Eaten by a Pliosaur

Uncovered in part by amateur fossil hunters in Australia, the fossil preserves a unique look at prehistoric predatory dynamics

The Solomon Siren by Jason deCaires Taylor honors Kale Island, which was submerged a decade ago due to rising sea levels. 

This Pacific Island Disappeared Under Rising Seas. A New Sculpture Marking the Spot Will Morph Into a Home for Seabirds, Coral and Marine Life

“The Solomon Siren” remembers Kale Island, submerged a decade ago in the Solomon Islands

Experts attached a satellite transmitter to Pancake's shell, which will track its location for up to 90 days.

An Endangered Kemp’s Ridley Sea Turtle Named Pancake Makes a Triumphant Return to the Ocean After Months of Rehabilitation

The cold-stunned turtle was rescued last fall on Cape Cod and has since made a full recovery. The reptile, whose sex remains unknown, is estimated to be between 2 and 5 years old and weighed 11 pounds at the time of release

A 52-foot-long model of a female Otodus megalodon is suspended from the ceiling at the Smithsonian National Museum of Natural History.

Predatory Sharks Grew to Enormous Sizes in Prehistoric Times. These Five Strategies Helped Them Get So Big

By cannibalizing their siblings in the womb or avoiding meat-eating pliosaurs, fearsome carnivores like the megalodon ballooned to proportions that would dwarf any shark alive today

Getting the device to transition between air and water seamlessly was one of the most challenging aspects of the work.

This Robot Can Flap Its Wings to Both Fly and Swim. It Might One Day Help Scientists Study Diving Birds and Survey Ocean Habitats

The bioinspired device, which weighs roughly half a pound and measures around three feet wide, was also modeled after aquatic birds like puffins, gulls and loons

Why Are These Whales Floating Upside-Down? They Might Just Be Moms Who Need a Break From Feeding Their Babies

Each year, southern right whales migrate thousands of miles from their feeding grounds to breed, give birth and raise their young. Taking rests and regulating their calves’ nursing schedules might help mothers conserve energy while they’re far from food

Known as Yowjab to Indigenous Australians, the inshore reef covers about 100,000 acres.

For Three Hours Every Day, Open Ocean Transforms Into Australia’s ‘Ghost’ Reef

An isolated wonder some 1,200 miles from the nearest city, Montgomery Reef disappears as quickly as it appears, mirroring the supposed vanishing of its original owners, a tribe of Indigenous giants

Commercial whalers hunted southern right whales to the brink of extinction. Though the species has rebounded, its recovery has been uneven.

Poop From Southern Right Whales Reveals That the Animals Might Be More Resilient to Climate Change Than We Thought

Scientists long believed that these whales, which swim throughout the Southern Hemisphere, mainly feasted on krill and small crustaceans called copepods, which are disappearing from the warming ocean. A new study suggests that the cetaceans have a more varied, flexible diet

Quest was purchased by explorer Ernest Shackleton for a Canadian Arctic expedition that was later aborted. He then set his sights on his fourth Antarctic expedition, but he died on the way. The ship was later used for seal hunting off Newfoundland and Labrador.

New Close-Up Images Reveal the Wreckage of Ernest Shackleton’s Last Ship, Now Draped in Discarded Fishing Gear and Teeming With Life

The vessel “Quest,” found in 2024 off the coast of northeastern Canada, has become a home for corals, anemones and fish. It also holds the leftovers from decades of commercial fishing that happened above it after it sank

Gripping onto the edge of an iceberg in East Greenland, a polar bear looks out across the sea ice and sniffs the air. “The scene reflects a landscape that never stays still, where ice fractures, drifts and reforms around it,” photographer Rhiannon Lawler of the United Kingdom writes in a caption. Lawler captured the photo with a drone, keeping a safe distance from the animal.
