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.

Chris and Angie explore Cookiecutter Sharks, small deep-sea predators that use suction, sharp teeth, and a twisting bite to leave neat circular wounds on much larger animals.

They discuss their strange appearance, warm-water range, nightly migrations, and glow-in-the-dark underside, which may help them hide or attract prey. The episode also looks at reproduction, rare reported human bites, and why these little-known sharks are so difficult to study. Finally, they place the species in the wider context of shark conservation, including the ongoing impacts of shark finning.

In this classic episode from 2020, Chris and Angie explore the remarkable sun bear—the world’s smallest bear and one of Southeast Asia’s most overlooked animals.

From their distinctive golden chest patch and extraordinary climbing skills to their love of insects, fruit, and honey, sun bears are perfectly adapted to life in tropical forests. But habitat loss, poaching, and the illegal pet trade continue to threaten these elusive bears. Join us to discover why sun bears matter, what makes them so unique, and why protecting their forest home protects so much more.

Sun bears remain listed as Vulnerable, with habitat loss and illegal trade among their major threats. IUCN Red List, Bornean Sun Bear Conservation Centre

Ecologist Dr. Amy McEuen joins Chris to discuss How to Think Like an Ecologist and the power of seeing the world as an interconnected system.

They explore ecosystem resilience, the value of nature connection, Amazon tipping-point debates, Indigenous land rights, biodiversity, freshwater, and nature-based climate solutions. Dr. McEuen also explains why misinformation spreads, why facts alone may not persuade people, and how values-based communication and “pre-bunking” can help. The episode closes with practical hope: collective action matters, and planting native species is one meaningful place to begin.
