Capybaras possess such a calm and gentle nature that many other animal species treat them as friends—including the birds who ride on their backs. In this episode, we follow a capybara as she lounges in the lagoon and covers herself in mud to repel bugs. And we’ll listen as she collectively parents her pups with the others in her herd, communicating through a complex language of whistles, clicks, and purrs.

At the southernmost tip of South Africa, where fresh and salt water collide, a tiny seahorse appears to levitate. Seahorses are the ocean’s slowest swimmers, but they have one of the world’s fastest muscle contractions, using it to suction up their prey. In this episode, we meander through eelgrass with a male Knysna seahorse as he twines tails with his partner, changes color to match the sand, and even gives birth to a brood of tiny seahorses.

Against the white expanse of the Arctic tundra, a snowy owl is hardly visible as he pauses to listen for the rustling of small prey. While most Arctic birds migrate south for the winter, this owl can survive through the endless polar nights. In this episode, we follow a snowy owl as he searches for food in the dark, soaring past the footprints of polar bears, howling huskies, and snow foxes that call this wintry world home.

In a quiet forest in Sweden, a cluster of Amanita muscaria mushrooms, with their iconic red caps dotted with white spots, push through a bed of soft reindeer moss. These crimson fungi interact with all manner of species in the forest—including a squirrel, who takes a nibble and wanders away in an altered state. These enchanted mushrooms also form partnerships with the trees, trading nutrients under the soil.

Humpback whales are among the most intelligent animals on Earth. Some scientists believe they might even surpass humans in self-awareness, empathy, and communication skills. In this episode, we swim with a whale as he teams up with other humpbacks to use bubbles to catch fish, rescues a sea lion, and puts his own spin on melodies sung by whales across the Pacific Ocean. This is the world in its natural state, defined by seasons, routines, and cycles. By the time this whale is ready to close one eye and go to sleep, you will be too.

California’s coast redwoods are Earth's tallest living beings, some reaching more than 350 feet high. They can also live for more than 2,000 years, outlasting entire civilizations. In this episode, we spend an evening with an ancient tree. Below ground, its roots tap into a forest-wide network; above ground, its branches harbor life in its many forms.

Get up close and personal with an amazing creature that has invaded our lexicon as well as our restaurants. It breathes with tubes, it has no head or brain, it feeds through a filter, and it is the source of dozens of familiar proverbs ("happy as a clam!"). Clams, it turns out, have been worshipped (by the Moche people of ancient Peru), used as money (by the Algonquin Indians), and consumed by people for thousands of years.

Movement Matters is a collection of essays in which biomechanist Katy Bowman continues her groundbreaking investigation of the mechanics of our sedentary culture and the profound potential of human movement. Here she widens her message and invites us to consider our personal relationship with sedentarism, privilege, and nature.

North Ronaldsay sheep have been roaming the shores of a Scottish isle for centuries. They outnumber people there by more than twenty to one. While most sheep graze in fields, the North Ronaldsay are a breed apart: they forage seaweed on the rocky beach. In this episode, we follow a lamb as she crosses the island’s ancient stone dyke and sees the ocean for the first time.

Sloths are the slowest mammals on earth. They can hardly see. They live in rainforests among jaguars, pumas, and countless other predators. Yet they survive. And they do it by being so incredibly slow, and living a life covered in algae. In this episode, we hang with a sloth in the jungle of Costa Rica as he spends a month digesting one single leaf, and we see the symbiosis and collaboration that surrounds him.

Platypuses are mammals unlike any other on earth. They lay eggs, ooze milk through their skin, and can sense electricity. In this episode, we travel with a platypus as he moves through his nightly routine on the island of Tasmania. He uses electroreceptors to hunt underwater and does a synchronized swimming courtship ritual with his mate, who then digs a burrow 40 feet deep into the riverbank to nest.

Red pandas have thick bushy ringed tails like raccoons, but they aren’t related to panda bears or raccoons—in fact, they have no close relatives anywhere on Earth. In this episode, we wander the Himalayas with a red panda and her cubs as they munch on bamboo, practice walking in the treetops, and settle in to nap together as the first snowfall of the year covers their forest home.

Sixty years ago in the snowy valleys of Japan, a young snow monkey discovered a hotel’s hot spring, and others in her troop soon joined her. Now, generations of families have built their routines around their own hot springs. In this episode, we follow a young snow monkey as her troop leaps from rock to rock toward their favorite activity in winter: a long steamy soak.

In the misty Puerto Rican El Yunque rainforest, coquí frogs no larger than your thumb fill the air with their distinctive two-note song: “co-quí, co-quí.” They alternate routines—one night singing to attract potential mates, the next hunting to fuel up for tomorrow’s performance. In this episode, we follow a singer and a hunter amid the vibrant nighttime chorus.

Crows have long been the subject of folklore, likely because they’re strikingly similar to humans, leading lives rich in personality, intelligence, and relationships. In this episode, we fly the streets of Seattle with a crow as she grooms her mate, delivers what appears to be a gift, and finally commutes miles away from her territory to gather and chat with thousands of other crows before it’s time to roost for the night.

Fennec foxes’ ears can be up to half as long as their bodies. They use them to track movement across the Sahara Desert, including under the sand. In this episode, we follow a fox as he meanders home to his family through the sand dunes as they slowly shift with the wind.

Timothy Morton argues that ecological awareness in the present Anthropocene era takes the form of a strange loop or Möbius strip, twisted to have only one side. Deckard travels this oedipal path in Blade Runner when he learns that he might be the enemy he has been ordered to pursue. Ecological awareness takes this shape because ecological phenomena have a loop form that is also fundamental to the structure of how things are.

The sun sinks over the Rio Grande, the mountains around it glow orange, and the world slows down. The Mexican free-tailed bats inside the Jornada Cave are just starting to stretch and murmur. In this episode, we visit the nursery where all the baby bats stay together, and we accompany a new mother as she journeys into the sky with the rest of her crew for a night of hunting bugs via echolocation.

Elephants are the largest land animals in the world. They are also intensely social and have advanced long-term memories. In this episode, a parade of Asian elephants makes its way through the Sri Lankan forest to a lake for drinks and mud baths, stopping periodically for group naps. The female leading the parade uses infrasonic rumbles—inaudible to humans, but traveling as far as two miles along the surface of the Earth as seismic waves—to invite friends and family around the forest to join her at the reservoir.

Brown bears lead deeply cyclical lives. They need to gain sometimes hundreds of pounds during the warmer months to prepare for winter hibernation, a lifestyle that brings them into frequent contact with many other species’ cycles. In this episode, we meander through the Alaska peninsula with a bear and her cubs as she teaches them to hunt salmon at the falls, dig for clams along the coastal mudflats, and use the regional rubbing tree.
