The Exotic Pet Trade Harms Animals and Humans. The European Union Is Studying a Potential Solution

News Feed
Monday, September 15, 2025

By the time a sugar glider named Mango entered an animal sanctuary in the Netherlands in 2023, life as a pet had taken a terrible toll. Mango lost both his brothers and his right eye due to health issues, despite being kept by a veterinarian for seven years. These days, Europeans keep tens of millions of exotic pets — as do people in other countries around the world.  Although beloved by their owners, experts say most of these animals, like Mango, do not adapt well to life in captivity and often face health problems and premature death as a result of this legal trade.

Courtesy Animal Advocacy and Protection Globally, the business involves an estimated 13,000 species, many unsuited to being companion animals, says Michèle Hamers, EU policy officer at the nonprofit Animal Advocacy and Protection. The organization runs the sanctuary where 9-year-old Mango lived — alongside fellow sugar gliders Radagast, Didache, Duizeltje, and Sushi — until his sudden death on July 21, likely from a hematoma. “Something needs to change,” says Hamers. For her organization, that change would involve the introduction of an EU-wide “positive list” for exotic pets — a limited inventory of approved pet species suited to captivity. They’re not the only ones asking for this. In recent years, momentum has grown toward making this a reality. The Pet Trade in Europe Sugar gliders are marsupials native to Australia, Indonesia, and Papua New Guinea named for their ability to “glide” through the air between trees on fleshy membranes connecting their front and back legs. Their arboreal, nocturnal lifestyles are among the traits that make them unsuitable for living in a cage in someone’s house, Animal Advocacy and Protection says. By their very nature of being wild, many other species don’t do well in captivity. As a result, the nonprofit’s rescue centers in the Netherlands and Spain take in as many exotic pets as they can. It’s never enough: they typically have a waiting list in the hundreds. Hamers says relinquished or seized animals typically arrive with behavioral and physical problems, including bone malformations, malnutrition, and stress-related issues like self-mutilation.

Photo: Elekes Andor via Wikimedia Commons To tackle the root cause of the situation, the organization and other concerned NGOs are pushing for EU-wide legislative change, preferably a “preventative approach” to regulating the trade. Hamers says this would establish a selective list of animals who can be kept, with all others banned by default. This type of system is known as positive, reverse, or whitelisting. Only animals who “can thrive in captivity and are safe to be kept” should make the cut, explains Hamers. Presently, the EU has no regulation designed to address the pet trade, although the market sometimes falls under laws concerning animal health, “invasive alien” species, and trade in threatened wildlife. Mostly, though, member states decide their own rules on exotic pets, which can vary greatly from country to country. Some EU nations don’t regulate the exotic pet trade at all, while others use a negative list system, meaning they create lists of banned species. The remaining member states — 12 out of 27 — have some form of positive list in place or the legal basis to develop them, says Hamers. In recent years European lawmakers have signaled support for an EU-wide positive list through varied resolutions and action plans. As a result the European Commission, which is the bloc’s executive body, commissioned a study on its feasibility in late 2023. The results are due later this year. On June 19, as part of a proposed regulation on the trade in pet cats and dogs, the European Parliament also voted in favor of establishing an EU-wide positive list for exotic pets, providing that the feasibility study shows the measure to be valuable and legally possible. One Trade, Many Problems In the proposed regulation, EU lawmakers warn that “the absence of a common Union framework” leads to “inconsistencies, gaps in enforcement, confusion for consumers and, often, to serious animal welfare consequences for species that are unsuitable to be kept as pets, as well as risks to biodiversity, human health and safety and nature conservation.” This statement illustrates why support for a positive list is gaining steam: the exotic pet trade is associated with several problems, not solely animal welfare. For Animal Advocacy and Protection, the welfare of kept animals is a priority. Whether captivity can meet animals’ physical and psychological needs should be the main criteria for considering who gets on the list, says Hamers. But, she adds, the criteria should include other factors, such as risks to biodiversity and public health and safety. A 2021 report by nonprofits Born Free and the RSPCA highlighted the potential risks exotic pets pose to public health. They include injuries and transmission of zoonotic pathogens: diseases like Covid-19 that can be passed between humans and other animals.

Photo: Michael Hoefner/Wikimedia Commons More than 85% of live animals traded globally are not native to the countries importing them, according to a 2023 analysis, which can pose a risk to environmental health. Hundreds of imported species have ended up being released into the wild, sometimes with dire consequences for native wildlife. For instance, scientists have implicated the trade in live amphibians for pets and meat in the global spread of the disease chytridiomycosis, which is linked to widespread amphibian population declines and 90 documented extinctions. On the flip side, trade can pose a threat to exploited species themselves. Scientists have calculated that 25% of the over 800 amphibian species traded as pets are threatened. They said further regulation and other measures are “urgently needed to slow the decline of populations and loss of species as a consequence of unsustainable, and largely unmonitored trade in wildlife.” Likewise, the industry is notorious for scooping up newly described species, often ones with limited ranges, to support collectors’ voracious desire for novelty. Positive lists could help to nip this unscrupulous inclination in the bud, because commerce in such species would be banned by default. Exotic pets are both sourced from the wild and bred in captivity. Breeding operations can relieve pressure on wild populations. But they can also be associated with illicit activity, such as the laundering of wild-caught animals into the captive-bred trade. In 2019, Belgium’s federal body for health, food chain safety, and environment, pointed to further links between captive breeding and illegality in a factsheet about the live amphibian trade. It stated, “illegal specimens are assumed to be the founding stock for many captive specimens, including within the European Union.” Illegal trade is a significant issue in the exotic pet business. A report by Traffic highlighted that 28% of all animals seized by EU countries in 2023 were likely destined to be pets, amounting to some 3,500 individuals. The lack of uniform regulation across the EU is a “massive problem” in this regard, says Hamers. Market fragmentation in a free trade bloc creates a ripe environment for illegal trade, she explains, because people can purchase animals banned in their own country from other EU states with relative ease. The United States has the same issue. In a 2023 paper, researchers noted that state and local regulations govern much of the trade, despite federal rules having some bearing on it, such as the Lacey Act’s prohibitions on the importation of certain “injurious” species. Differing and incomplete rules across states, alongside lackluster penalties for wrongdoing, have “facilitated continued possession of exotic pets in states where these animals are banned,” the researchers warned. They concluded the U.S. would benefit from a nationwide positive list system, too. Making Positive Lists Meaningful Even with captive breeding, many exotic pets being traded across the EU and the U.S. originated from countries elsewhere, says Peter Lanius, director of the Australian nonprofit Nature Needs More. Lanius’ organization released a report in June outlining how a global positive list for exotic pets could be introduced by the global wildlife trade treaty body, the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Alongside yardsticks like considering species’ welfare needs and mortality rates in captivity, it argues that a determining factor should include whether trade is easy to monitor.   View this post on Instagram   A post shared by ShaldonZoo (@shaldonzoo) This ties to the report’s broader theme: the importance of establishing a robust regulatory architecture around positive lists, which the authors say is generally lacking even for the few that already exist. Pet industry advocates have described existing lists in European countries and elsewhere as “unenforceable,” the report notes. “If you stop at the point where you just list what can be traded, but there’s no infrastructure… it’s symbolic, not practical,” insists Lynn Johnson, Nature Needs More’s founder and CEO. Positive lists must be accompanied by “dedicated monitoring and enforcement capacity,” according to the report. Nature Needs More also calls for businesses to be registered, licensed, and required to provide end-to-end traceability for the animals they trade. Owners should be required to register exotic pets too, the report says, with the veterinary profession engaged in maintaining care standards. Other outlined provisions include creating a listing authority to determine and perpetually review the positive list, as well as interventions to reduce consumer demand for banned species. The organization also calls for legislation to compel social media companies to police commerce on their sites by making them liable for traded animals. The organization says financing these provisions should come from a business levy on traders. None of these ideas are revolutionary, the nonprofit stresses. Nations have imposed similar regulatory measures on the pharmaceutical and chemical industries. But the model would be a massive step for the wildlife trade, which typically lacks adequate monitoring and enforcement. A Trivial Trade in Living Beings This January the European Pet Organization — which bills itself as “the voice of the pet sector at European level” — released a position statement on positive lists. In contrast to ornamental fish trade veteran Tim Haywood, who told The Revelator last year that the number of species in the pet fish trade must shrink, the pet organization rejected the idea of “restrictive measures” such as positive lists. The group suggested poor welfare and illegality in the trade are limited and could be dealt with through improved enforcement of existing legislation and education of consumers. It also argued that restricting petkeeping through positive lists wouldn’t stop determined owners from buying forbidden exotic animals. However, a Finnish study found that many hobbyists are put off from buying exotic pets when the animals are subject to trade restrictions. Hamers has further reason to doubt that a positive list system will lead to significant rises in illegal petkeeping. The trade is “hyper-commercialized,” she explains, and “many purchases are done on the whim,” often driven by popular culture trends like movies or social media. “Once species aren’t for sale anymore through common channels, the possibility to buy an animal on an impulse also disappears,” says Hamers. For Nature Needs More, the often-trivial nature of modern-day pet purchasing makes positive listing so necessary. Although the keeping of exotic pets has occurred for centuries, substantially more people can casually engage it now due to having the money, time, and access to animals in “our globalized, industrial society,” its report says. “When a trade in living beings is allowed to function by the rules of the throw-away consumer society, then we have a serious problem,” the organization warns.

Costa Rica Shifts Toward Regenerative Tourism Alongside Other Nations

Costa Rica has long stood out for its commitment to protecting natural areas through tourism. Now, our country joins a growing number of nations that push beyond basic protection.

Costa Rica has long stood out for its commitment to protecting natural areas through tourism. Now, our country joins a growing number of nations that push beyond basic protection. They aim to restore and improve ecosystems damaged by past activities. This approach, called regenerative tourism, changes how visitors interact with places they travel to. In Costa Rica, tourism generates over 8 percent of the national economy and supports hundreds of thousands of jobs. For decades, the focus stayed on sustainability—keeping beaches clean, forests intact, and wildlife safe without causing more harm. But recent efforts show a clear move to regeneration. Local projects work to rebuild habitats, boost biodiversity, and strengthen communities hit hard by environmental changes. Take Punta Leona, a coastal area in Puntarenas. Hotels there add a small fee to each booking, with funds going directly to conserve local plants and animals. This has helped protect scarlet macaws and other species facing threats from habitat loss. In the Arenal area, Rancho Margot operates as a self-sustaining farm and lodge. It grows its own food, recycles water, and teaches guests how to plant trees that restore soil eroded by old farming practices. These actions do more than maintain the status quo; they repair what was lost. Costa Rica’s government backs this trend. The Tourism Board promotes programs that encourage visitors to join conservation work, such as planting mangroves along the Pacific coast or monitoring sea turtles in Tortuguero. A group called Costa Rica Regenerativa advises businesses on how to integrate regeneration into their operations. They focus on holistic plans that cover social, cultural, and environmental needs. As a result, areas like Monteverde see improved cloud forest health, with reforestation efforts bringing back native species absent for years. This shift aligns with global patterns. New Zealand sets a strong example. Its tourism authority invites travelers to participate in restoring native forests and waterways. In places like Rotorua, canopy tours fund projects that remove invasive plants and protect geothermal sites. The country reports higher visitor satisfaction when people contribute to these efforts, leading to longer stays and more repeat trips. Saudi Arabia takes a different path but shares the goal. It invests in large-scale regeneration in desert regions, turning arid lands into green spaces through water management and planting programs. Tourism there now includes experiences where guests help with these restorations, drawing interest from eco-conscious travelers. Finland emphasizes carbon neutrality in its northern landscapes. Cities like Helsinki offer tours that involve cleaning up lakes and planting boreal forests. This not only offsets travel emissions but also enhances wildlife corridors for species like reindeer. Ecuador’s Galápagos Islands provide another case. Strict rules limit visitor numbers, but regenerative programs let people assist in removing invasive species and monitoring marine life. Revenue from these activities funds habitat restoration, helping giant tortoises and other endemic animals thrive. In Mexico, Playa Viva on the Pacific coast runs as a regenerative resort. It restores mangroves and coastal dunes while involving local communities in decision-making. Guests leave with a sense of having improved the place they visited. These examples show regenerative tourism spreading across continents. It responds to rising awareness of climate change and biodiversity loss. Travelers today seek meaningful trips that give back, and nations like Costa Rica benefit from this demand. Studies from the World Travel & Tourism Council indicate that regenerative practices can increase tourism revenue by up to 20 percent in participating areas, as they attract higher-spending visitors. Challenges remain. Mass tourism can strain resources, as seen in some Costa Rican beaches where overcrowding leads to pollution. To counter this, experts call for better regulations and education. Community involvement stays key—local people must lead these initiatives to ensure they meet real needs. Looking ahead, Costa Rica plans to expand regenerative models nationwide. Partnerships with international organizations aim to share knowledge with other countries. This positions the nation as a guide in the field, showing how tourism can heal rather than just preserve. As more nations adopt this model, the travel industry may see lasting change. For us here in Costa Rica, it means building a healthier future for our land and people.

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.
