National Geographic filmmaker Bertie Gregory returns to All Creatures Podcast to share the story behind Wolves Up Close, filmed in the bitter cold around Hudson Bay. He shares what seven years following Kona’s pack taught him about how wolves lead and hunt, and recounts a close encounter with a polar bear. Chris and Bertie explore why we love dogs yet fear wolves, how wolf kills feed other wildlife, and what it takes for people and wolves to coexist.

Wolves Up Close premiered November 6 in the U.S. on National Geographic, Disney+ and Hulu.

El Niño is strengthening across the Pacific, and its effects can ripple far beyond the ocean.

Chris breaks down what El Niño actually is, how it shifts weather patterns around the world, and why this event matters for people, wildlife, and ecosystems.

From drought, flooding, and heat to disrupted marine food webs, coral bleaching, wildfire risk, and changing breeding patterns, this episode explores how one natural climate cycle can influence life across the planet.

Chris also looks at how human-caused climate change is altering the background conditions in which El Niño now occurs, and why forecasting, preparation, and resilient ecosystems matter more than ever.

Imagine living for more than 200 years in one of the harshest environments on Earth. Meet the bowhead whale, the longest-lived mammal known to science and an extraordinary survivor of the Arctic.

Chris and Angie discover what makes bowheads so special, from enormous, ice-breaking skulls and blubber nearly half a metre thick to the longest baleen plates of any whale. These Arctic giants sustain their massive bodies largely on tiny crustaceans, including copepods and krill.

Their conservation story combines recovery with continuing concern. Commercial whaling devastated bowhead populations, but protection has allowed some to rebound. Today, fishing-gear entanglement, ship strikes, underwater noise and a rapidly changing Arctic present ongoing challenges for these remarkable whales.

Chris and Angie return after a National Geographic event with photographer Amy Vitale and introduce an episode on sand dollars, prompted by Angie finding live sand dollars with her family and wanting answers to her kids’ questions.

They describe sand dollars as flat, burrowing echinoderms with an internal calcium-carbonate “test,” tiny spines and cilia, petaloid patterns with tube feet for respiration, slow movement and burrowing.

They also discuss global distribution, size variation, feeding as deposit feeders. Major threats include bottom trawling/dredging and ocean acidification; they suggest using Monterey Bay Aquarium’s Seafood Watch and highlight the National Marine Sanctuary Foundation and practical pollution-reduction steps.

Imagine a shark swimming through the Arctic today that was already alive before the United States existed. Greenland sharks are thought to be the longest-lived vertebrates on Earth, with research suggesting they can live for around 400 years—and potentially longer. Even more astonishing, females may take approximately 150 years to reach reproductive maturity. These slow-growing inhabitants of the cold North Atlantic and Arctic oceans live on a timescale that is almost impossible to comprehend.

We’re revisiting this classic All Creatures Podcast episode following renewed headlines about a controversial proposal to kill 1,000 Greenland sharks. Earlier this year, Greenland’s Avannaata municipality approved a bounty scheme in response to fishers’ concerns about damaged equipment and lost catch. The scheme was subsequently dropped because the municipality lacked the legal authority to implement it, but the debate over killing these extraordinary animals continues.

Greenland sharks are classified as Vulnerable on the IUCN Red List. Historically hunted for their liver oil, they now face ongoing threats from accidental capture in fishing gear, while climate change may alter their Arctic habitat. Their population size remains poorly understood, and their exceptionally slow growth and late maturity make them particularly susceptible to overfishing. Join us as we revisit one of the ocean’s most remarkable animals—and why protecting a creature whose life spans centuries requires thinking far beyond our own lifetimes.

From the archives of All Creatures Podcast, we're revisiting our inspiring 2021 conversation with Dr. Paula Kahumbu, one of Africa's most influential wildlife conservationists, a National Geographic Explorer, and recipient of the prestigious Whitley Gold Award.

As a leading voice in elephant conservation, Dr. Kahumbu has dedicated her career to protecting Africa's wildlife, combating the illegal ivory trade, and inspiring a new generation of conservationists. Through her leadership at WildlifeDirect and her groundbreaking television series Wildlife Warriors, she has helped bring African conservation stories to millions while championing local communities and African-led conservation efforts.

Fresh off our own live podcast event at National Geographic, we're celebrating another extraordinary Explorer whose passion, determination, and leadership remind us that protecting wildlife begins with empowering the people who share their world.

Chris recounts the recovery of New Zealand’s Chatham black robin (karure/keruru), an island species devastated by habitat clearing and introduced predators like rats and cats, until its range shrank to tiny Mangere Island.

Numbers fell from 18 birds in 1972 to seven in 1976, then to five by 1980 with only one breeding female, “Old Blue,” paired with “Old Yellow,” leaving the species’ future dependent on her.

Chris tells the story of how conservationists and the New Zealand Wildlife Service team, led by figures like Don Merton, combined translocation, predator control, habitat restoration (including planting about 120,000 trees), and pioneering cross-fostering led to this species survival.

What kind of animal can see light we cannot and strike with enough force to crack a crab’s shell? In this classic episode from 2022, Chris and Angie meet the mantis shrimp: a small marine predator with extraordinary eyes and one of the most powerful hunting strikes in the animal world. Some species smash hard-shelled prey, while others use sharp, spear-like limbs to catch fish.

“Mantis shrimp” refers to hundreds of species, so there is no single conservation status for them all. Some face pressure from fishing and the loss of the reefs and seabed habitats they call home. Join us for one of our favorite classic episodes and discover why this remarkable creature deserves attention far beyond its famous punch.

In this classic episode from 2019, Chris and Angie explore the cheetah’s incredible speed, from its flexible spine and gripping claws to the long tail that helps it turn during a chase. But there is much more to this remarkable cat than its sprint.

Cheetahs are currently listed as Vulnerable globally, while the remaining Asiatic cheetahs in Iran are Critically Endangered. Across their range, shrinking and fragmented habitat leaves cheetahs with less space and fewer wild prey. Many live alongside farmers, where conflict over livestock can lead to cheetahs being killed; cubs are also taken for the illegal pet trade.

Join us to discover why the cheetah’s future depends on protecting connected landscapes and finding ways for people and wildlife to live together.

Chris speaks with Atlanta Journal-Constitution reporter Drew Kann about Georgia’s Okefenokee Swamp and its new status as a UNESCO World Heritage Site.

They explore the swamp’s blackwater wetlands, remarkable wildlife, and delicate balance of fire and water. Drew explains how a proposed titanium mine raised concerns about water loss, severe fires, and damage to nearby rivers—until public opposition and a conservation land purchase stopped the project. They also discuss the power of local journalism and why continued protection remains essential.
