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.

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.

Dung beetles might sound dirty, but the ancient Egyptians believed their god took the form of a dung beetle to roll the morning sun across the sky every day. In this episode, we roll with dung beetles around the world as they push their precious dung—often in balls many times larger than they are—over Florida pastures, Armenian highlands, and the vast South African savanna.

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.

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.

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.

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.

Dogs are a familiar and comforting part of many of our lives. In this episode, we take a walk with a pet xoloitzcuintli, or Mexican hairless dog, as he greets his blocks by smell. Along the way, we learn the backstory of squirrels in U.S. cities and observe the very smart and clean neighborhood raccoon.

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.

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.

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.

Bats can hear shapes, plants can eat light, and bees can dance maps. When his life took him to a painfully dark place, the poet behind The CryptoNaturalist, Jarod K. Anderson, found comfort and redemption in these facts and the shift in perspective that comes from paying a new kind of attention to nature. Something in the Woods Loves You tells the story of the darkest stretch of a young person’s life, and how deliberate and meditative encounters with plants and animals helped him see the light at every turn.

We all take for granted the idea that being in nature makes us feel better. But if you were a skeptic who wanted hard scientific evidence for this idea, where would you look? And how would that evidence be gathered? It wasn't until Dr. Kathy Willis was asked to contribute to an international project looking for the societal benefits we gain from plants that she stumbled across a study that radically changed the way she saw the natural world. In the study there was clear proof that patients recovering from gall bladder operations recovered more quickly if they were looking at trees.

A riveting exploration of how microbes are transforming the way we see nature and ourselves - and could revolutionize agriculture and medicine. Prepare to set aside what you think you know about yourself and microbes. Good health - for people and for plants - depends on Earth's smallest creatures. The Hidden Half of Nature tells the story of our tangled relationship with microbes and their potential to revolutionize agriculture and medicine, from garden to gut.

All ancient and indigenous peoples insisted their knowledge of plant medicines came from the plants themselves and not through trial-and-error experimentation. Less well known is that many Western peoples made this same assertion. There are, in fact, two modes of cognition available to all human beings - the brain-based linear and the heart-based holistic. The heart-centered mode of perception can be exceptionally accurate and detailed....

At age sixteen Sophie Strand—bright, agile, fearless—is suddenly beset by unexplained, debilitating illness while on a family trip abroad. Her once vibrant life becomes a tangled miasma of medication, specialists, anaphylaxis, and seemingly never-ending attempts to explain what has gone so terribly wrong. And, for many years thereafter, Sophie's life becomes subsumed with ideas not of "health," but of explanation, and the narrative of how and why she became sick. But slowly, she comes to another, more fundamental understanding of what has happened to her body.

In Bite, zoologist Bill Schutt makes a surprising case: it is teeth that are responsible for the long-term success of vertebrates. The appearance of teeth, roughly half a billion years ago, was an adaptation that allowed animals with backbones, such as fish, amphibians, reptiles, birds, dinosaurs and mammals—including us—to chow down in pretty much every conceivable environment.
