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.

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.

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.

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.

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.

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.

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.

Axolotls are nature's ultimate Peter Pan—amphibians that never transform past the larval stage. Found only in Mexico’s ancient lake system of Xochimilco, they've survived since the time of the Aztecs, a people who considered them sacred. In this episode, we glide through the cool, dark water with an axolotl, meandering through the floating gardens these charming creatures call home.

By the time I turned 30, my health was slipping into dangerous territory. That was when I decided to reclaim my life, not as a patient, but as a curious postdoctoral researcher and sensible biohacker. This book is the story of how two ...

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.
