In a world where news about endangered species is often bleak, a sprawling underwater canyon off the coast of Nova Scotia is offering something rare: hope. There, in the dark, nutrient-rich waters of the Gully, a vast submarine canyon roughly the size of the Grand Canyon, Canada’s northern bottlenose whales are making a remarkable recovery. Once hunted to near collapse, these deep-diving whales are now rebounding after decades of protection, a new study published in the Journal of Applied Ecology found. “This study really does provide excellent evidence that knowledge of a species, its needs and its threats can be used to generate conservation success,” said Ari Friedlaender, a marine ecologist at the University of California, Santa Cruz, who was not involved in the research. What makes the Gully special The Gully’s dramatic topography consists of steep walls, deep channels, and strong ocean currents, and creates ideal conditions for marine life to flourish. “At the broadest scale, submarine canyons stir up the oceanography, and that typically translates into more productivity, life and food—good for everything!” said Hal Whitehead, marine biologist at Dalhousie University and co-author of the study. This makes the Gully a perfect year-round home for the Scotian Shelf population of northern bottlenose whales, a group classified as endangered by the Committee on the Status of Endangered Wildlife in Canada. Whitehead first encountered these whales in 1977 and was struck by their unusual friendliness. “These wonderful whales came up to the boat. Unlike most whales, they were friendly,” he recalled. “I thought, wow, that’s very cool.” Unfortunately, that same friendliness made them easy targets during the commercial whaling era. Before Canada banned whaling in 1972, whalers exploited their curious nature. “The whales would come around, and they just slaughtered them all,” Whitehead said. From collapse to cautious optimism By the mid-2000s, decades of whaling and continued threats from fishing gear and ship strikes had pushed the Scotian Shelf population to just 130 individuals. But in 2004, a turning point came when Canada designated the Gully as a Marine Protected Area (MPA) under legislation first passed in 1996. This law gave the government authority to protect ecologically valuable marine zones. “We worked with experts to find places that are high value for conservation and good science,” said Paul Macnab, senior oceans biologist and project lead for the Gully MPA. Though not involved in the study, Macnab noted the Gully was chosen as a place where the effectiveness of marine protection could be properly tested. In the Gully’s core zone, commercial fishing and other harmful activities were banned, protecting both the whales and the prey they rely on. Tracking the impact of protection To understand whether the protections were actually helping, researchers used 35 years of observational data, analyzing both whale sightings and human activity in the area. What they found was promising. Fishing and vessel traffic had declined significantly in the heart of the MPA. Meanwhile, the whale population grew by nearly two-thirds, reaching an estimated 210 individuals by 2023. That’s more than were present when Whitehead first studied them nearly five decades ago. A rare marine conservation win Globally, northern bottlenose whales still face challenges. Low birth rates and ongoing risks like fishing gear entanglement continue to slow recovery in other regions. But in the Gully, years of consistent protections and monitoring have paid off. “The Gully is one of the few places where we’ve been able to track a distinct population long enough to see real trends,” said Whitehead. Still, as encouraging as the rebound is, scientists caution that a single protected canyon is not enough. Many marine species, including whales, migrate across vast ocean areas. “For many other species, it’s only part of their habitat, and we have to protect them in a lot of other ways,” Whitehead said. That means developing networks of protected zones that safeguard marine life not just where they feed, but where they travel. The bigger picture The Gully’s whales show what’s possible when science, policy, and long-term monitoring come together. It also highlights how marine protected areas, if properly enforced, can make a measurable difference for endangered species. At a time when biodiversity loss dominates global headlines, the story from this deep-sea canyon is a reminder that recovery is possible with the right tools and commitment. And that, sometimes, protection pays off, not just for whales, but for the planet.

For our Best of 2025 Science roundup, we’re celebrating the breakthroughs that didn’t just advance human knowledge; they sparked possibility, opened new frontiers, and reminded us why curiosity is a superpower. Dolphins have long fascinated scientists for their intelligence, empathy, and complex social behaviors. Now, researchers believe they may be on the verge of decoding a more intricate piece of dolphin communication: a system that bears resemblance to human language. In a groundbreaking study, scientists at the Woods Hole Oceanographic Institution (WHOI), along with partner institutions like the Sarasota Dolphin Research Program (SDRP), have found the first potential evidence that bottlenose dolphins might use shared, word-like sounds known as non-signature whistles (NSWs). “Bottlenose dolphins have long fascinated animal communication researchers,” said Dr. Laela Sayigh, the study’s lead researcher at WHOI. “Our work shows that these whistles could potentially function like words, shared by multiple dolphins.” Beyond names: decoding the non-signature whistle Much of past research on dolphin communication has centered around “signature whistles” (SWs), distinctive sounds used by individual dolphins as personal identifiers, similar to names. But NSWs, which make up about half of dolphin vocalizations, have remained largely understudied. Thanks to a 50-year acoustic archive built by the SDRP in Sarasota, Florida, researchers were able to analyze the rarely examined NSWs. In their work, the team catalogued 22 distinct NSW types, including two whistles they labeled NSWA and NSWB, which are produced by at least 25 and 35 dolphins, respectively. These shared whistles, unlike the individualistic SWs, are stereotyped; they repeat patterns that could serve as universal signals within the dolphin community. A new whistle, a possible meaning To study the function of these sounds, the team used underwater digital tags and suction-cup hydrophones to capture vocalizations from identified dolphins. They then conducted playback experiments in the wild to observe dolphin responses. “We found that [NSWA] typically elicits avoidance responses, leading us to believe that it may have an alarm-type function,” Sayigh explained. The other call, NSWB, appears to function more like a query. “This whistle may be produced in response to an unexpected stimulus, perhaps as a way of inquiring what it is,” she said. Sayigh emphasized that these interpretations are still hypotheses, noting that dolphins’ reactions to NSWB have been mixed. “Responses to playbacks of NSWB have been variable, which could support a variety of functions, including our suggested function as a query.” Are dolphins using a form of language? The implications of these findings are significant. Since dolphins are known for lifelong vocal learning, a rare trait among mammals, and use referential SWs, the researchers believe it’s plausible that NSWs are also learned and convey meaning. “Our study provides the first evidence in dolphins for a wider repertoire of shared, context-specific signals, which could form the basis for a language-like communication system,” the study authors wrote. Still, Sayigh is cautious. “We have only suggested that NSWs may be word-like, in the sense that they may have specific meanings that are understood by multiple animals,” she said. More research is needed to determine whether dolphins truly use language-like structures. Global recognition for pioneering work The study has earned the research team the inaugural Coller Dolittle Challenge prize. Jeremy Coller, the challenge’s founder, praised the team for helping bridge the communication gap between humans and animals. “Humans share this planet with millions of other species, but for far too long we’ve only talked among ourselves,” he said. The researchers hope to use artificial intelligence to further analyze their extensive dataset and deepen our understanding of dolphin communication. As Sayigh put it, “We don’t want to leave any patient behind, no matter how small they are.” Her sentiment reflects a growing scientific curiosity and ethical imperative to listen more closely to the creatures with whom we share the oceans.
