See 15 Stunning Images From the Ocean Photographer of the Year Awards

News Feed
Thursday, September 12, 2024

The vastness of the ocean evokes both wonder and mystery. And for centuries, photographers have been trying to capture its essence. Since the first underwater photography began in 1856, technology has evolved to allow divers to take breathtaking images that bring to life this unique ecosystem. The Ocean Photographer of the Year Contest, sponsored by Oceanographic Magazine and Blancpain, channels the passion of ocean photographers into a yearly competition. The contest has a simple mission: “To shine a light on the wonder and fragility of our blue planet and celebrate the photographers giving it a voice.” This year, photographers from around the globe submitted more than 15,000 coastal, drone and underwater images to the contest. The shots fell into seven categories: wildlife, fine art, adventure, conservation impact, conservation hope, human connection and young photographer. The competition awards an overall winner—the Ocean Photographer of the Year—in addition to category winners, the Ocean Portfolio Award honoring a photographer’s collection of work and the Female Fifty Fathom Award, which celebrates a boundary-pushing woman in ocean photography. Winners of the 2024 contest were announced September 12, and the recognized photographs include dramatic wildlife encounters, beautiful examples of humans’ connection with the ocean and stark reminders of society’s impact on the marine environment. The image winners will go on exhibition at the Australian National Maritime Museum in Sydney, Australia, on November 28, followed by several yet-to-be-announced venues in early 2025. Below are the stunning images awarded in this year’s contest, as well as a selection of finalists that also wowed the judges. Overall Winner, Rafael Fernández Caballero A Bryde’s whale opens its mouth, about to devour a heart-shaped bait ball in Baja California Sur, Mexico. Rafael Fernández Caballero The overall winning image shows a Bryde’s whale about to devour a bait ball—a last-ditch defensive measure that occurs when fish swarm together and pack tightly, typically performed by small schooling fish when they feel threatened by predators. In the photo, light shines through the water. Research suggests Bryde’s whales spend most of the day within 50 feet of the water’s surface. While this school of fish may seem like a hearty snack, Bryde’s whales eat an estimated 1,320 to 1,450 pounds of food daily—so this whale likely fed again shortly after. “The image captures perhaps the most special—and craziest—moment of my life,” says photographer Rafael Fernández Caballero in a statement. “It fills me with joy having lived this moment—and to have captured the image.” Female Fifty Fathoms Award Winner, Ipah Uid Lynn A tiny goby perches on a delicate sea whip, surrounded by colors at Romblon Island in the Philippines. Ipah Uid Lynn Ipah Uid Lynn, a Malaysian photographer, took home the Female Fifty Fathoms Award with her body of work that featured this colorful image of a goby. This award works differently than the others. Instead of submitting photos, the recipient is nominated by her peers and judged by a special panel. “It’s a recognition that goes beyond personal achievement,” Lynn says in a statement. “It highlights the importance of storytelling through photography and the voices of women in this field.” This vibrant photograph highlights the beauty of small creatures in the ocean. It depicts a goby resting on a sea whip, a type of soft coral. Sea whips can grow to two feet in total height, making this a spectacular close-up capture. Portfolio Award Winner, Shane Gross Baby plainfin midshipman fish, still attached to their yolk sacs. Shane Gross Canadian photographer Shane Gross encountered this group of baby plainfin midshipman fish still attached to their yolk sacs in British Columbia, Canada. For these fish, it’s the males that provide parental care. While the plainfin midshipman is known to be a deep-sea marine fish, it transcends habitats during the breeding season in summer and migrates to the fluctuating intertidal zone. As the tide moves in and out, the fish face changing temperatures and oxygen levels. While the fish might swim in comfortable cold water in the morning, their rocks could be completely exposed to air in the afternoon. Despite this stressful environment, the male midshipman remains to care for his young. The babies “are guarded over by their father until they are big enough to swim … to ocean depths,” Gross says in a statement. Human Connection Winner, Zhang Xiang A beach reflects the golden haze of the sunset while a traditional fisher wades through the water in Fujian, China. Zhang Xiang A traditional Chinese fisher traverses a beach as the sunset’s golden haze is reflected by the sand and water. China is the world’s largest seafood producer and exporter, accounting for about 35 percent of global production. The sea around China contains 3,000 marine species, of which more than 100 are fished commercially, including mackerel, anchovy, shrimp and crab. Here, the beauty of the landscape brings another economic value to the area in Fujian province. “The gorgeous sight attracts many tourists, bringing income to local people,” photographer Zhang Xiang says in a statement. Adventure Winner, Tobias Friedrich A scuba diver is dwarfed by a shipwreck in the Bahamas. Tobias Friedrich The photo above was a surprise find for German photographer Tobias Friedrich. “We were on a liveaboard cruise to take underwater images of tiger and hammerhead sharks,” he says in a statement. “But due to bad weather conditions, we had to seek shelter and look for alternative dive sites. We decided to dive on this wreck … At that time, the sand under the bow was washed out, which made it an excellent photographic opportunity.” The region surrounding the Grand Bahama has 176 shipwrecks, according to an analysis of historical records done last year. The ship pictured above was intentionally sunken by a dive center. Known as scuttling, this practice of purposefully sinking ships has grown; it can produce dive training sites and increase revenue options for dive centers. However, some scuttling has also been done for ecological reasons, helping to create new artificial reef sites for fish. Conservation (Hope) Winner, Shane Gross A green sea turtle is released by a researcher after being accidentally captured while trying to catch sharks. Shane Gross This green sea turtle was accidentally caught by researchers when they were trying to find sharks. Here, the creature is returned to the ocean after a researcher untangled it from the net, took measurements and tagged the turtle for conservation purposes. Tagging an animal is a crucial way for scientists understand and learn about its species. The practice could help researchers understand migratory patterns, lifespan and how the species spends time. Shane Gross, who snapped the photo, remarks on the future of the tagged green sea turtle: “She is now an ambassador for her species.” The green sea turtle is the largest hard-shelled sea turtle. As herbivores, the animals’ diet of seagrasses and algae gives their fat a greenish color. Green sea turtles can be found worldwide, nesting in more than 80 countries and swimming in the coastal areas of more than 140 countries. Conservation (Impact) Winner, Frederik Brogaard A fin whale, the second-biggest whale species on Earth, at a whaling plant in Iceland. Frederik Brogaard For the 2024 hunting season, Iceland made the controversial decision to distribute a license to a whaling company for the hunting of fin whales. Above, a dead fin whale waits to get butchered at a whaling plant before being sent to Japan. “The picture might induce a feeling of hopelessness, but public uproar throughout the last two years has resulted in the cancellation of last year’s whaling season in Iceland. Unfortunately, a whaling quota was again issued this year,” says Frederik Brogaard, the Denmark-based photographer who captured this image, in a statement. “I hope this picture raises awareness and serves as an inspiration to keep the public pressure on. These whales are crucial in our fight against climate change, sequestering tonnes of CO2 in their lifetime, and are worth more to us alive than dead.” Young Ocean Photographer Winner, Jacob Guy An elusive algae octopus shows off its fluorescence under ultraviolet light in North Sulawesi, Indonesia. Jacob Guy The algae octopus is elusive. “Normally coming out to hunt at dusk, with incredible camouflage, these creatures blend seamlessly into the reef—until they are viewed under a different light,” says photographer Jacob Guy of the United Kingdom in a statement. He spotted this individual off of North Sulawesi, Indonesia. “On my last dive of the trip, I got lucky and found one of these beautiful creatures on the hunt for a meal and managed to capture the intense look from its yellow eyes.” Under ultraviolet light, the algae octopus has an uncommon ability—it glows with fluorescence, absorbing the light to emit it at visible wavelengths. But in its resting camouflage state, the animal looks like a shell overgrown with algae—which is how it gets its name. When an algae octopus is hungry, you may find it in an unexpected place: on land. It can move between tidal pools on a beach when hunting for crabs. Fine Art Winner, Henley Spiers Juvenile Munk’s devil rays are attracted by a green light on a boat, seemingly flying through the water in the Sea of Cortez, Baja California Sur, Mexico. Henley Spiers Munk’s devil rays, like the ones above, are found in tropical oceanic waters of the eastern Pacific Ocean. Munk’s devil rays are quite acrobatic. They can leap out of the water, either alone or in groups, performing vertical jumps and somersaults. They mainly feed on opossum shrimp and zooplankton but can also eat small fish. The rays are known to form enormous congregations when feeding, resting or—in at least one instance—mating. Henley Spiers of the U.K. describes in a statement how he captured the photo: “At night, we hung a green light from the back of our boat. As plankton gathered around it, the mobula rays gratefully swooped in for a microscopic buffet. The rays seem to fly through the water as they pursue their dinner. Entranced by their glance, I used a two-second exposure to capture their movements, which, to my eye, felt like an aquatic ballet.” Wildlife Winner, Manuel Castellanos Raboso A mahi-mahi, also called a common dolphinfish, proudly displays its catch amidst a feeding frenzy. Manuel Castellanos Raboso A sunlit mahi-mahi enjoys its catch from the bait ball behind it in Baja California Sur, Mexico. The large fish, which can grow to seven feet long, eat a variety of species, including small pelagic fish, juvenile tuna and invertebrates. Mahi-mahi can reproduce at a relatively young age, as early as four to five months old, and their productivity is one reason why scientists assume the mahi-mahi population is stable. “Its vibrant yellow and green hues shimmer brilliantly under the refracted sunlight against the stunning blue of the Pacific Ocean,” Spanish photographer Manuel Castellanos Raboso says in a statement. “[The mahi-mahi were] moving like torpedoes in front of us. This scene captures the hunt and the energy of the Baja’s marine life.” Finalist, Jake Wilton This rare leucistic green sea turtle was discovered among nests, supported by local conservation efforts, in Papua New Guinea’s Conflict Islands. Jake Wilton Typical sea turtles have deep green coloring, but the individual above has a rare condition: leucism. An animal with leucism experiences a partial loss of pigmentation. This often leads to white coloration in splotches on the animal’s skin or fur. Leucism is not exclusive to turtles; it can be found in horses, cows, cats, dogs, crocodiles, penguins and other species. Notice the dark color of the turtle’s eyes in the photo—this is one trait that distinguishes leucism from albinism, since leucism does not affect the eyes’ pigmentation. Albino animals, on the other hand, have pink, red or light blue eyes. For Australian photographer Jake Wilton, hitting the shutter with just the right timing was critical to achieving this shot. “Using the surface of the calm water, I captured the striking reflection of the hatchling as it surfaced for air,” Wilton says in a statement. In Papua New Guinea’s Conflict Islands, conservation efforts have boosted the numbers of turtle hatchlings. The discovery of this rare leucistic turtle, Wilton adds, “is a testament to the successful turnaround in conservation efforts and the beauty of these endangered creatures.” Finalist, Filippo Borghi One of the Southern Ocean’s most formidable predators, the leopard seal, approaches the camera with its mouth wide open. Filippo Borghi “In the frigid waters of the Southern Ocean, just off the coast of Antarctica, I had the opportunity to capture a breathtaking encounter with one of the region’s most formidable predators—the leopard seal,” says Italian photographer Filippo Borghi in a statement. The leopard seal, sometimes referred to as a sea leopard, is the second-largest species of seal in the Antarctic, behind the southern elephant seal. Its only natural predator is an orca. Sea leopards feed on fish, squid, small crustaceans, penguins, smaller seals and even whale carcasses. Borghi describes his nerves the moment he got the shot. “I held my breath, my heart racing with a mixture of awe and trepidation, as the seal approached, its spotted coat and powerful jaws seeming suspended in the crystalline waters,” he adds. “[Its] dark eyes were fixed on mine.” Finalist, Daisuke Kurashima A diver swims through colorful waters off Iwo Jima. Daisuke Kurashima Iwo Jima is one of the Japanese Volcano Islands, a group of three islands in Micronesia governed by Japan. The effect displayed in the photo above is a product of a special environmental feature of Iwo Jima: hot springs. “When the water from the hot springs flows into the sea, the shallower the water is, the more red or orange it turns,” Japanese photographer Daisuke Kurashima says in a statement. “The visible colors in the water vary depending on the concentration of the hot spring’s components, and the appearance is compared to an aurora borealis.” Finalist, Edwar Herreño Parra Beside the Sharkwater research vessel, which was initially used by the Japanese fishing fleet, swims a whale shark with its distinctive spotted pattern. Edwar Herreño Parra The boat pictured above, aptly named Sharkwater, is a former fishing ship turned research vessel. Beneath it swims an endangered whale shark. Whale sharks have distinctive spotted patterns on their backs, which help divers and researchers to photograph and track individuals more easily. Despite their name, whale sharks are not whales—though they are some of the largest creatures in the ocean. Whale sharks can weigh up to 30 tons and even grow larger than a school bus. Like whales, they are filter-feeders, meaning they eat by straining plankton through their gills. Adult whale sharks do not stay with their young after birth, and only around 10 percent of them make it to adulthood. However, if they grow to adult size, the sharks enjoy a lifestyle with few predators, meaning they can enjoy a long life of up to 150 years. Colombian photographer Edwar Herreño Parra describes his moment with the shark on a tagging expedition. “I stayed in the water with the shark for almost an hour trying to take an image of the endangered species below the scientific vessel. It all came together, and the moody lighting and the rough sea add to the image’s appeal,” he says in a statement. Finalist, Kate Jonker An octopus peeks curiously out from its hiding spot in South Africa. Kate Jonker Octopuses are some of the most physically flexible creatures in all of nature. Beyond this, the common octopus featured here excels at camouflaging with its surroundings. The cephalopod achieves this feat through a network of pigment cells called chromatophores just below the surface of its skin. South African photographer Kate Jonker describes her encounter with the hiding creature in a statement: “This little common octopus was so well camouflaged among the hydroids that I almost missed it. It would peek out, then hide, lifting its head cautiously.” Octopuses are quite intelligent—they can complete puzzles, untie knots and open jars. Interestingly, their intellect is based in a different kind of anatomy than humans’—about two out of three of their neurons are located not in their head, but in their arms. Jonker adds that she spent about 15 minutes just watching this creature, “noticing its curiosity and caution. Gradually, it became braver, spending more time observing me and my camera. Eventually, it allowed me to capture its photo before slipping away beneath her rock.” Reflecting on the experience of getting the shot, Jonker notes that “moments like these are humbling, reminding us we are visitors in their environment, yet they are willing to share a connection.” Get the latest stories in your inbox every weekday.

The winning and highly commended underwater photography spotlights breathtaking animal behavior, conservation needs and the otherworldly environment of Earth's oceans

In Alaska’s Warming Arctic, Photos Show an Indigenous Elder Passing Down Hunting Traditions

An Inupiaq elder teaches his great-grandson to hunt in rapidly warming Northwest Alaska where thinning ice, shifting caribou migrations and severe storms are reshaping life

KOTZEBUE, Alaska (AP) — The low autumn light turned the tundra gold as James Schaeffer, 7, and his cousin Charles Gallahorn, 10, raced down a dirt path by the cemetery on the edge of town. Permafrost thaw had buckled the ground, tilting wooden cross grave markers sideways. The boys took turns smashing slabs of ice that had formed in puddles across the warped road.Their great-grandfather, Roswell Schaeffer, 78, trailed behind. What was a playground to the kids was, for Schaeffer – an Inupiaq elder and prolific hunter – a reminder of what warming temperatures had undone: the stable ice he once hunted seals on, the permafrost cellars that kept food frozen all summer, the salmon runs and caribou migrations that once defined the seasons.Now another pressure loomed. A 211-mile mining road that would cut through caribou and salmon habitat was approved by the Trump administration this fall, though the project still faces lawsuits and opposition from environmental and native groups. Schaeffer and other critics worry it could open the region to outside hunters and further devastate already declining herds. “If we lose our caribou – both from climate change and overhunting – we’ll never be the same,” he said. “We’re going to lose our culture totally.”Still, Schaeffer insists on taking the next generation out on the land, even when the animals don’t come. It was late September and he and James would normally have been at their camp hunting caribou. But the herd has been migrating later each year and still hadn’t arrived – a pattern scientists link to climate change, mostly caused by the burning of oil, gas and coal. So instead of caribou, they scanned the tundra for swans, ptarmigan and ducks.Caribou antlers are stacked outside Schaeffer's home. Traditional seal hooks and whale harpoons hang in his hunting shed. Inside, a photograph of him with a hunted beluga is mounted on the wall beside the head of a dall sheep and a traditional mask his daughter Aakatchaq made from caribou hide and lynx fur.He got his first caribou at 14 and began taking his own children out at 7. James made his first caribou kill this past spring with a .22 rifle. He teaches James what his father taught him: that power comes from giving food and a hunter’s responsibility is to feed the elders.“When you’re raised an Inupiaq, your whole being is to make sure the elders have food,” he said.But even as he passes down those lessons, Schaeffer worries there won’t be enough to sustain the next generation – or to sustain him. “The reason I’ve been a successful hunter is the firm belief that, when I become old, people will feed me,” he said. “My great-grandson and my grandson are my future for food.” That future feels tenuous These days, they’re eating less hunted food and relying more on farmed chicken and processed goods from the store. The caribou are fewer, the salmon scarcer, the storms more severe. Record rainfall battered Northwest Alaska this year, flooding Schaeffer’s backyard twice this fall alone. He worries about the toll on wildlife and whether his grandchildren will be able to live in Kotzebue as the changes accelerate.“It’s kind of scary to think about what’s going to happen,” he said.That afternoon, James ducked into the bed of Schaeffer’s truck and aimed into the water. He shot two ducks. Schaeffer helped him into waders – waterproof overalls – so they could collect them and bring them home for dinner, but the tide was too high. They had to turn back without collecting the ducks. The changes weigh on others, too. Schaeffer’s friend, writer and commercial fisherman Seth Kantner grew up along the Kobuk River, where caribou once reliably crossed by the hundreds of thousands. “I can hardly stand how lonely it feels without all the caribou that used to be here,” he said. “This road is the largest threat. But right beside it is climate change.”The Associated Press receives support from the Walton Family Foundation for coverage of water and environmental policy.

Changes in polar bear DNA that could help the animals adapt to warmer climates have been detected by researchers, in a study thought to be the first time a statistically significant link has been found between rising temperatures and changing DNA in a wild mammal species.Climate breakdown is threatening the survival of polar bears. Two-thirds of them are expected to have disappeared by 2050 as their icy habitat melts and the weather becomes hotter.Now scientists at the University of East Anglia have found that some genes related to heat stress, ageing and metabolism are behaving differently in polar bears living in south-east Greenland, suggesting they may be adjusting to warmer conditions.The researchers analysed blood samples taken from polar bears in two regions of Greenland and compared “jumping genes”: small, mobile pieces of the genome that can influence how other genes work. Scientists looked at the genes in relation to temperatures in the two regions and at the associated changes in gene expression.“DNA is the instruction book inside every cell, guiding how an organism grows and develops,” said the lead researcher, Dr Alice Godden. “By comparing these bears’ active genes to local climate data, we found that rising temperatures appear to be driving a dramatic increase in the activity of jumping genes within the south-east Greenland bears’ DNA.”As local climates and diets evolve as a result of changes in habitat and prey forced by global heating, the genetics of the bears appear to be adapting, with the group of bears in the warmest part of the country showing more changes than the communities farther north. The authors of the study have said these changes could help us understand how polar bears might survive in a warming world, inform understanding of which populations are most at risk and guide future conservation efforts.This is because the findings, published on Friday in the journal Mobile DNA, suggest the genes that are changing play a crucial role in how different polar bear populations are evolving.Godden said: “This finding is important because it shows, for the first time, that a unique group of polar bears in the warmest part of Greenland are using ‘jumping genes’ to rapidly rewrite their own DNA, which might be a desperate survival mechanism against melting sea ice.”Temperatures in north-east Greenland are colder and less variable, while in the south-east there is a much warmer and less icy environment, with steep temperature fluctuations.DNA sequences in animals change over time, but this process can be accelerated by environmental stress such as a rapidly heating climate.There were some interesting DNA changes, such as in areas linked to fat processing, that could help polar bears survive when food is scarce. Bears in warmer regions had more rough, plant-based diets compared with the fatty, seal-based diets of northern bears, and the DNA of south-eastern bears seemed to be adapting to this.Godden said: “We identified several genetic hotspots where these jumping genes were highly active, with some located in the protein-coding regions of the genome, suggesting that the bears are undergoing rapid, fundamental genetic changes as they adapt to their disappearing sea ice habitat.”The next step will be to look at other polar bear populations, of which there are 20 around the world, to see if similar changes are happening to their DNA.This research could help protect the bears from extinction. But the scientists said it was crucial to stop temperature rises accelerating by reducing the burning of fossil fuels.Godden said: “We cannot be complacent, this offers some hope but does not mean that polar bears are at any less risk of extinction. We still need to be doing everything we can to reduce global carbon emissions and slow temperature increases.”

A Deadly Pathogen Decimated Sunflower Sea Stars. Look Inside the Lab Working to Bring Them Back by Freezing and Thawing Their Larvae

For the first time, scientists have cryopreserved and revived the larvae of a sea star species. The breakthrough, made with the giant pink star, gives hope the technique could be repeated to save the imperiled predator

A Deadly Pathogen Decimated Sunflower Sea Stars. Look Inside the Lab Working to Bring Them Back by Freezing and Thawing Their Larvae For the first time, scientists have cryopreserved and revived the larvae of a sea star species. The breakthrough, made with the giant pink star, gives hope the technique could be repeated to save the imperiled predator Juvenile sunflower sea stars at the Sunflower Star Laboratory in Moss Landing, California. At this phase, each is less than an inch wide, but they can grow to be more than three feet across as adults. Avery Schuyler Nunn Key takeaways: Recovering sunflower sea stars by freezing them in time Ravaged by infectious bacteria, sunflower sea stars literally wasted away across the Pacific coast of North America—and their resulting population crash destabilized kelp forest ecosystems. Scientists pioneered a cryopreservation technique on the closely related giant pink star, raising hopes that a bank of frozen sunflower star larvae could one day be thawed in the same way and released into the wild. Along a working California harbor, where gulls wheel over weathered pilings and the old Western Flyer—the ship John Steinbeck once sailed to the Sea of Cortez—sits restored in its berth, researchers buzz about in a modest lab tucked between warehouses and boatyards. Inside, amid the hiss of pumps and the faint smell of brine from seawater tables, a scientist lifts a small vial from a plume of liquid nitrogen, its frosted casing holding the tiniest flicker of hope for a species on the brink. Each of the 18 vials contains between 500 and 700 larval giant pink sea stars. At this stage, they are tiny specks suspended in seawater, invisible to the naked eye. These particular larvae have been cryopreserved and stored at roughly minus 180 degrees Celsius since March. At the Sunflower Star Laboratory (SSL) in Moss Landing, California, scientists thawed the larval pink sea stars and coaxed them to successfully develop into juveniles this summer—a first for any sea star species. In October, the scientists thawed another batch of larvae from the same cohort to test larval growth and survival under different freezing conditions and thawing protocols. The breakthrough, however, isn’t really about the giant pink star, a species that’s common in the wild. Instead, these larvae serve as a crucial stand-in for the far more imperiled sunflower sea star (Pycnopodia helianthoides)—a vanishing species for which larvae are precious, limited and increasingly difficult to obtain. Perfecting cryopreservation methods on pink stars—ensuring they can survive freezing, resume feeding and grow into juveniles—lays the scientific groundwork for facilitating a return of Pycnopodia. The contents of a thawed vial are placed under a microscope to assess viability of the larvae. Avery Schuyler Nunn The discovery arrives at a precarious time, as sunflower stars have disappeared at a pace rarely seen in marine ecosystems. As a mysterious pathogen ravaged their population along the western shores of North America beginning in 2013, the creatures collapsed from an estimated six billion individuals to functional extinction in parts of their range—all within just a few years. Their loss left kelp forests with dramatically fewer predators, destabilizing ecosystems across the Pacific coast and allowing urchins to proliferate and graze formerly lush underwater canopies into barren rock. Now, scientists hope that “freezing” their larvae will offer a new avenue for bringing the species back. “Cryopreservation is particularly important on the population level when thinking about recovery for this endangered species, because it had major population losses,” says Marissa Baskett, an environmental scientist at the University of California, Davis, who was not involved in the project. The process lets scientists preserve the sea stars’ existing genetic diversity for future reintroduction to the wild, she adds. “Especially given the uncertainty about different disease outbreaks, having that stock to return to is incredibly valuable.” A mysterious and “complete collapse” Sunflower sea stars have long lived in abundance up and down the rugged Pacific coast—from Alaskan archipelagoes to Baja California. The 24-limbed echinoderms sprawled across the seafloor in shades of ochre, crimson and violet. Among the fastest-moving and largest of all sea stars—capable of stretching nearly three feet across—these radiant predators coursed through kelp forests, voraciously hunting purple sea urchins and preventing them from over-grazing on the holdfasts that root towering golden canopies of kelp. An adult sunflower sea star has 24 limbs and can be more than three feet wide. This one was photographed off Point Dume State Beach near Los Angeles. Brent Durand via Getty Images “In Northern California and Oregon, there historically would have been multiple keystone predators within the kelp forest ecosystem who are punching on purple urchins and keeping their population in check,” says Reuven Bank, board chair of SSL. “But the southern sea otter was extirpated across its historic range, so we were left with sunflower stars being the last major keystone predator of purple urchins across over 100 miles of coastline.” “And sunflower stars didn’t just eat urchins, they scared them,” Bank adds. “Urchins can smell a sunflower star approaching, and in healthy kelp forests they hide more and graze less. Even without consuming them, sunflower stars helped keep urchin behavior, and therefore kelp forests, in balance.” Then, in June 2013, tidepool monitors along Washington’s Olympic Peninsula documented an unprecedented sight. The once-sturdy sea stars had turned soft, pale and contorted, their arms curling and detaching from their bodies. By late summer, the same mysterious affliction had surfaced in British Columbia, and it began sweeping both north and south with startling speed. The emerging epidemic, which caused the invertebrates to literally disintegrate, would soon be known as sea star wasting disease. An infamous marine heatwave—nicknamed “The Blob”—had settled over the Pacific by 2014, thrusting the coast into a fever. Ocean temperatures spiked, likely speeding up the disease progression in already stressed sea stars and leading to higher mortality. In the warm, stagnant water, infected sunflower stars dissolved at an eerily rapid pace, leaving behind ghost-white films of bacterial mass where the vibrant predators had been just days before. “You’d have apparently healthy stars basically melt away into puddles of goo within 48 hours,” says Andrew Kim, lab manager at SSL. “It happened so quickly, and I don’t think folks were prepared for the ensuing ecosystem shift. You don’t often expect diseases to come through and totally reshape ecosystem dynamics within such a short period. But that’s what we saw.” Without sunflower sea stars to keep those spiny purple urchins in check, the balance began to falter, setting the stage for an unprecedented chain reaction. Urchin populations skyrocketed, grazing on kelp without limits, and once-thriving underwater forests collapsed into barren rock. A dense group of purple sea urchins, which exploded in population after the sunflower sea stars disappeared, photographed near Mendocino Headlands State Park, north of San Francisco. Brent Durand via Getty Images In California, with 99 percent loss, sunflower sea stars are now considered functionally extinct. “Even though there may be a few remnant individuals left, they can no longer fulfill their historic role in the ecosystem,” Bank says. As sunflower stars unraveled in the wild, another species—its thick-armed cousin, the giant pink star—offered an unexpected foothold for hope. The pink stars share a nearly identical geographic range and life history with sunflower stars, and crucially, their larvae can be raised in aquaria. If scientists could learn to freeze and revive the pink star in its early life stages, they wondered, could that knowledge become a lifeline for the sunflower star? That’s where the small team in Moss Landing stepped in. Freezing sea stars for the future What these scientists did was something no one had ever pulled off with a sea star. Working with giant pink stars, researchers spawned adults at the Aquarium of the Pacific in Long Beach, California, fertilized their gametes to produce thousands of larvae, and shipped those microscopic bodies to the Frozen Zoo—a cryopreserved archive of creatures operated by the San Diego Zoo Wildlife Alliance. There, reproductive scientists plunged the larvae into liquid nitrogen, cooling them to extremely low temperatures and pausing their cells’ biological activity. The larvae, essentially frozen in time, were shielded from ice crystal damage with special cryoprotectant mixtures. Sunflower Star Laboratory researchers remove a vial of pink star larvae from an insulated cooler at around minus 180 degrees Celsius in preparation for thawing. Avery Schuyler Nunn After months in this suspended state, the larvae were sent to the Sunflower Star Laboratory where Carly Young, a San Diego Zoo Wildlife Alliance scientist who advances cryopreservation and reproductive-rescue tools, led the team in thawing the vials. She had fine-tuned the ideal way to keep the larvae alive as they returned to real-world temperatures, carefully testing more than 100 “recipes” with various warming rates, cryoprotectant dilutions and rehydration steps. The pink star larvae not only survived thawing, but have thus far lived all the way through metamorphosis into juveniles. Scientists watched the little stars settle spontaneously along the bottom of their beakers just 19 days after revival. The success prompted the team to apply the same cryopreservation protocols to sunflower star larvae from the Alaska SeaLife Center. The larvae will be frozen in perpetuity, creating the first-ever cryopreserved archive of the species—like a seed bank, but for the baby sea stars. “A famous quote from the ’70s, when the Frozen Zoo in San Diego was established, was, ‘You must collect things for reasons you don’t yet understand,’” says Ashley Kidd, conservation project manager at SSL. “We don’t know when the other shoe is going to drop and what populations are going to look like as the planet changes. So, rather than chasing ghosts around the ocean floor, we really focused on what we can do with animals that are currently under human care somewhere.” While cryopreservation itself isn’t a ready-made restoration tool, it opens the door to conserving genetic diversity of a species and banking rare lineages for potential reintroduction to the wild. In the 1970s and 1990s, researchers began testing cryopreservation of marine invertebrates with sperm and larvae, establishing the basic protocols that this team could apply to sea stars. The breakthrough doesn’t restore kelp forests by itself, but the SSL scientists note that cryopreservation creates something the conservation community has desperately needed: time. Time to hold onto genetic diversity, time to refine captive rearing and time to prepare for future reintroduction at scales big enough to matter. The ultimate test, the researchers say, will be translating the thawing process to sunflower sea stars. Carly Young, at the Sunflower Star Laboratory, looks for movement in the young sea stars. Avery Schuyler Nunn Just this summer, scientists uncovered a piece of the puzzle that had eluded them for more than a decade: the pathogen behind sea star wasting disease. In a four-year international effort, researchers traced the outbreak to a strain of the marine bacterium Vibrio pectenicida. When cultured and injected into healthy sea stars, it reproduced the telltale symptoms—softening arms, rapid disintegration and death within days. The finding, published in Nature Ecology and Evolution in August, gives recovery teams a way to test for the pathogen in labs and hatcheries, tighten quarantine measures and understand disease risks before returning captive-bred sea stars to the Pacific. “It’s massively important to know what to look for, and the fact that we are now able to test for this disease is going to be critical in advancing our ability to move forward with reintroductions and continuing the research,” notes Kim. “We’ve already been able to take fluid samples from all of our stars and get them analyzed for the presence of Vibrio pectenicida, so we’ve mobilized very quickly on the heels of development.” Paired with this new diagnostic clarity, advances in cryopreservation offer a second front in the effort to save the species. Frozen larvae can be stored for decades and offer flexibility for selective breeding of disease-tolerant traits, notes the team. Cryopreservation adds another tool to the scientists’ toolbox as they fight to prevent the species—and, in turn, its ecosystem—from wasting away. “Bringing back sunflower stars,” Bank says, “is the single-most important step we can take toward restoring kelp forest balance.” Get the latest Science stories in your inbox.

Archaeologists Are Unraveling the Mysteries Behind Deep Pits Found Near Stonehenge

Based on a comprehensive study, researchers are now convinced the shafts were human-made, likely dug during the Late Neolithic period roughly 4,000 years ago

Archaeologists Are Unraveling the Mysteries Behind Deep Pits Found Near Stonehenge Based on a comprehensive study, researchers are now convinced the shafts were human-made, likely dug during the Late Neolithic period roughly 4,000 years ago Sarah Kuta - Daily Correspondent December 10, 2025 9:59 a.m. The pits are evenly spaced around a large circle. University of Bradford In 2020, archaeologists in the United Kingdom made a surprising discovery. At Durrington Walls, a large Neolithic henge not far from Stonehenge, they found more than a dozen large, deep pits buried under layers of loose clay. The pits are mysterious. Each one measures roughly 30 feet wide by 15 feet deep, and together they form a mile-wide circle around Durrington Walls and neighboring Woodhenge. They also appear to be linked with the much older Larkhill causewayed enclosure, built more than 1,000 years before Durrington Walls. For the last few years, archaeologists have been puzzling over their origins: Were they dug intentionally by human hands? Were they naturally occurring structures, like sinkholes? Or is there some other possible explanation for the existence of these colossal shafts? Quick fact: The purpose of Durrington Walls While Stonehenge is thought to have been a sacred place for ceremonies, Durrington Walls was a place where people actually lived. In a new paper published in the journal Internet Archaeology, archaeologists report that they have a much better understanding of the pits’ purpose, chronology and environmental setting. And, now, they are confident the shafts were made by humans. “They can’t be occurring naturally,” says lead author Vincent Gaffney, an archaeologist at the University of Bradford, to the Guardian’s Steven Morris. “It just can’t happen. We think we’ve nailed it.” Chris Gaffney, an archaeologist at the at the University of Bradford, surveys the ground near Durrington Walls. University of Bradford For the study, researchers returned to the site in southern England and used several different methods to further analyze the unusual structures. They used a technique known as electrical resistance tomography to calculate the pits’ depths, and radar and magnetometry to suss out their shapes. They also took core samples of the sediment, then ran the soil through a variety of tests. For instance, they used optically stimulated luminescence to determine the last time each layer of soil had been exposed to the sun. They also looked for traces of animal or plant DNA. Astonishing' Stonehenge discovery offers new insights into Neolithic ancestors. Together, the results of these analyses indicate humans must have been involved, which suggests the pits could be “one of the largest prehistoric structures in Britain, if not the largest,” Gaffney tells the BBC’s Sophie Parker. Researchers suspect the circle pits were created by people living at the site over a short period of time during the Late Neolithic period roughly 4,000 years ago. They were not “simply dug and abandoned” but, rather, appear to have been part of a “structured, monumental landscape that speaks to the complexity and sophistication of Neolithic society,” Gaffney says in a statement. For example, the pits are fairly evenly spaced around the circle, which suggests their Neolithic creators were measuring the distances between them somehow. “The skill and effort that must have been required to not only dig the pits, but also to place them so precisely within the landscape is a marvel,” says study co-author Richard Bates, a geophysicist at the University of St Andrews, in a statement. “When you consider that the pits are spread over such a large distance, the fact they are located in a near perfect circular pattern is quite remarkable.” Researchers used multiple methods to investigate the pits at Durrington Walls. University of Bradford But who dug the pits? And, perhaps more importantly, why? Archaeologists are still trying to definitively answer those questions, but they suspect the shafts were created to serve as some sort of sacred boundary around Durrington Walls. Their creators may also have been trying to connect with the underworld, per the Guardian. “They’re inscribing something about their cosmology, their belief systems, into the earth itself in a very dramatic way,” Gaddney tells the BBC.

Is red meat bad for you? Limited research robs us of a clear answer.

We’d all appreciate more definitive guidance. Eating a varied diet is a wise move while we wait.

Over and over, we ask the question: Is Food X good or bad for you? And, over and over, belief in the answer — whether it’s yes or no — is held with conviction totally out of proportion with the strength of the evidence.Today’s illustration: red meat. It has become one of the most-disputed issues in food. It’s so polarizing that some people decide to eat no meat at all, while others decide to eat only meat. It’s poison, or it’s the only true fuel.The latest salvo in the Meat Wars was kicked off by a new report that outlines the optimal diet for both people and planet. The EAT-Lancet Report comes down hard on red meat; its recommended daily intake is a mere 14 grams — that’s half an ounce.Read on, and the news gets worse: “Because intake of red meat is not essential and appears to be linearly related to higher total mortality and risks of other health outcomes in populations that have consumed it for many years, the optimal intake may be zero.”Note that word: “related.” It’s the source of the problem with the report and its recommendation.The EAT-Lancet report, by researchers from 17 countries, bases its recommendation solely on observational data. When you do that, meat comes out looking pretty bad. In study after study, people who report eating a lot of meat have worse health outcomes than people who eat little. Meat-eating correlates with increased risk of heart disease, some cancers and all-cause mortality.But, as always with observational research that attempts to connect the dots between diet and health, the key question is whether the meat itself, or something else associated with a meat-heavy lifestyle, is actually causing the bad outcomes.That’s a hard question to answer, but there are clues that people who eat a lot of meat are very different from people who eat a little.Let’s look at a study, published in JAMA Internal Medicine, cited by the EAT-Lancet report; it has a convenient demographic summary. According to it, people in the top one-fifth of meat eaters are different from people in the bottom fifth in a lot of important ways: They weigh more, they’re more likely to smoke, they’re not as well-educated, they get less exercise, and they report lower intakes of fruit, vegetables and fiber. On the plus side, they report drinking less alcohol. But other than that, we’re looking at a litany of markers for a lifestyle that’s not particularly health-conscious.So, to suss out whether it’s the meat that’s raising disease risk, you have to somehow correct for any of the differences on that list — and most of that information also comes from observational research, so even the confounders are confounded.Then there are the things you can’t correct for. Sleep quality, depression and screen time, for example, all correlate with some of the same diseases meat correlates with, but most studies have no information on those.All this confounding explains one of my all-time favorite findings from observational research. It comes from the same study the demographics came from (analyzed in a 2015 paper). Sure enough, the people who ate the most meat were more likely to die of cancer and heart disease, but they were also more likely to die in accidents. And the biggest difference came from the catchall category “all others,” which invariably includes causes of death that have nothing to do with meat.Basically, there’s a very simple problem with relying on observational research: People who eat a lot of meat are very different from people who eat less of it. The meat definitely isn’t causing the accidental deaths (unless, perhaps, they’re tragic backyard grill mishaps), and it isn’t causing at least some of the “all others” deaths, so we know that heavy and light meat-eaters are different in all kinds of ways.That’s where controlled trials come in.In a perfect world, we could figure this out by keeping a large group of people captive for a lifetime, feeding half of them meat, and seeing what happens. Okay, maybe that’s not a perfect world, but it would be the best solution to this particular problem.Instead, we have trials that are short-term (because of logistics and cost), and necessarily rely on markers for disease, rather than the disease itself. For that to be useful, you need a marker that’s a reliable indicator. For a lot of diseases — including cancer — those are hard to come by. For heart disease, we have a good one: low-density lipoprotein (LDL) cholesterol. So, most of the controlled trials of meat-eating focus on heart disease.If you spend some time reading those trials (and I did, so you don’t have to), you find that most of them show some increase in LDL cholesterol, although it’s generally small.A 2025 analysis of 44 controlled trials on meat found that the only ones showing positive cardiovascular outcomes had links to the meat industry, and even then, only about one in five came out positive. Of the independent studies, about three-quarters showed negative outcomes, and the remaining one-quarter was neutral.This isn’t surprising. Red meat contains saturated fat, and we have countless trials that demonstrate sat fat’s ability to raise LDL. But if the meat you eat is relatively lean, that effect is going to be small.The lesson here is that we don’t have a lot of good evidence on meat and health. The observational evidence is hopelessly confounded, and the evidence from clinical trials is woefully limited. There’s so much we simply don’t know. There may be other ways meat raises risk (leading to over-absorption of heme iron and stimulating the production of TMAO, or trimethylamine N-oxide), but there’s little definitive evidence for them. And, of course, there’s the question of what you eat instead. If you’re eating red meat instead of, say, instant ramen, that may be an improvement. If, instead, you’re cutting back on your lentils, not so much.As always, the single-most important thing to remember about nutrition is that what we know is absolutely dwarfed by what we don’t know. Which means that, if you’re making decisions based on what we do know, you could very well be wrong.So what’s an eater to do? Meat is a nutritious food. In fact, animal foods are the only natural sources of a vitamin we need — B12 — which is an indication that we evolved with meat and dairy as part of our diet. It’s very hard to know whether eating some lean meat leads to better outcomes than eating no meat, but I think some meat is a good hedge against all that uncertainty. (The ethical and environmental concerns are also important, but for today let’s focus on health.)But plant foods are also nutritious. And eating a wide variety of them is also a good hedge against uncertainty. Which means the carnivore diet — all meat, all the time! — is a pretty bad bet.Unfortunately, “uncertainty” is not a word that features prominently in the Meat Wars. Instead, we have an unappetizing combination of nastiness and sanctimony, with each camp convinced that the truth and the light are on their side.Not that this is a metaphor for our times or anything.
