Terrestrials
Welcome, nature lovers, to the home of the Terrestrials podcast and family-friendly Radiolab episodes about nature. Every other week, host Lulu Miller will take you on a nature walk to encounter a plant or animal behaving in ways that will surprise you. Squirrels that can regrow their brains, octopuses that can outsmart their human captors, honeybees that can predict the future. You don’t have to be a kid to listen, just someone who likes to see the world anew. You’ll hear a range of nature stories on this podcast. Sometimes these will be brand new Terrestrials episodes, full of o...
The Greeting: Yo-Yo Ma's Humpback Whale Experiment
As one of the most famous cellists of all time, Yo-Yo Ma has spent a lot of time playing music inside. But a few years ago, he decided to take the cello out of the fancy concert halls and into nature, bringing our very own Producerbud Ana along for the ride!
That brings us to humpback whales. Like Yo-Yo, humpbacks are musical. They communicate through melodies, clicks, grunts, whispers, and bellows. Human beings still don’t fully know what the whales are saying to each other, but for Yo-Yo it sounds just like cello music. So, he had...
The Red-Eyed Mascot: Loon Resilience in Minnesota
What do loons have to do with courage and community? In January, we received a letter from two sisters in Minnesota - Jude and Mo. They wrote to us because their city was experiencing a lot of unrest, with immigration agents arresting members of their community and protests ringing loud in the streets as people tried to protect their neighbors. And in the middle of it all, an unexpected symbol began appearing on storefronts, stickers, and even as tattoos: the black and white, migrating waterbird known as the loon. Jude and Mo were curious: why are loons a good s...
The Snowball: Extreme Squirrels in the Arctic (Replay)
Middle schooler, Aanya, has an up-close encounter with a squirrel in the school yard, which leads her to an obsession with one of North America's most common critters. She tells host Lulu Miller all about the overlooked superpowers of squirrels, including one squirrel who lives way up in the Arctic, where the weather gets so cold the squirrels who live there drop their body temperatures down below freezing and somehow, miraculously, survive.
Host Lulu travels to Alaska to meet one of these squirrels as it sleeps, and Lulu talks with biologists Dr. Kelly Drew and Dr. Brian...
The Snoozer: Penguin Slackerzzz Rule
How rested would you feel if you took 10,000 naps a day? Chinstrap Penguins in Antarctica spend their days taking MICRONAPS, each around 4 seconds long. To learn why, Lulu meets one (played by Songbud Alan), who explains how micronaps help them conserve energy and protect their babies from “sky pirates”! Then, in a badgermania, penguin scientists Dr. Eric Wagner and Dr. Dee Boersma answer your questions! Why are penguins black-and-white? Why is their poop pink? What might they dream about? And we learn that what may look like laziness… turns out to be an evolutionary superpower.
Don’t sleep on t...
Build-A-Dragon (Replay)
On February 17, in places like China, Malaysia, Korea and Chinatowns across the globe, dragons will rise in the form of massive puppets. Today we bring you a special Terrestrials episode on dragons to understand what they have to do with the New Year, what the dragon myth means, and explore the tiny chance that dragons could have ever been real.
First, we meet Mr. Lu Dajie, one of China's most renowned dragon dancers, who tells us about the significance of dragons in China. Then producer bud Ana and song bud Alan ask whether there’s any chance tha...
The Portal: Groundhogs Lead Us Into an Underrealm of HOLES
Holes are full of a whole lot of nothin'. Pure, hollow emptiness. At least that’s what Songbud Alan thought before he fell down a rabbit hole of, well, HOLES! In honor of Groundhog Day, he takes Lulu to a fossil-filled pit behind a Chick-fil-A to dig up 66-million-year-old treasure, and deep down to an underwater hole where blobs of colorful microbes reveal a time when Earth’s days were only 6 hours long. We discover eyeless cave fish, fall into a sinkhole of Corvettes, and go house hunting for the perfect animal hole to cozy up in... which leads us t...
The Spellbook: Ancient Recipes for Animals
Where do animals come from? That's something people have been trying to explain for thousands of years. And for a while, scientists and philosophers believed that any ol' person could create creatures if they just had the right recipe. A touch of sand, maybe a drop of blood and POOF: you could create life. That idea was believed to be true for generations until one brave scientist decided to look more closely at an unlikely bug and change the course of science forever. Lulu calls up our biology correspondent, Dr. Avir Mitra, to solve this ancient mystery.

The Present: A Gift from our Furry Friends
To celebrate New Year’s Day, there are all kinds of traditions. Some people eat black eyed peas for good luck, some list out resolutions. But here at Terrestrials, we are taking a cue from the wisdom of pets, who are so, so, so good at sleeping. After a short preamble from Lulu, we’ll turn the microphone over to listeners’ furry friends snoring and snoozing in various positions, places, and locations. The piece will be largely wordless, with some narration from listeners describing their pets, and sound designed as a sort of meditation to rest.
HEY GR...
The Slowpoke: How Sloths Grow Invisibility
Sloths are the slowest mammals on Earth. How can a creature that moves so slowly survive in a world that moves so fast? Zoologist Lucy Cooke helps us rethink everything we know about sloths and their slowness. We follow a sloth named Nacho from a rainforest to a nightclub, trek deep into mangrove swamps to find a rare pygmy sloth and uncover the secret that allows sloths to evade even the deadliest predators. Hint: it has to do with a special kind of invisibility.
For more, check out Lucy’s A Little Book of Sloth and her slo...
The Bridge: How Rainbows Connect Worlds
What is a rainbow? An optical illusion? Or a thing out there in the world? For centuries, cultures around the world believed that rainbows were bridges - pathways to gods and to the afterlife. Then in 1665, during a plague, a young Isaac Newton made a discovery that changed everything : sunlight is made of many colors. He counted 7. But artists, poets and curious children weren’t convinced. How could a rainbow only have seven colors? Their skepticism led to a far stranger discovery that would revolutionize how we understand the universe. - In the end, we learn that rainbows are kin...
The Fuzzy Ruckus: The Power of Lichen
Artist Ashley (Ash) Eliza Williams was so shy growing up that they found it hard to speak to people. Instead, they withdrew from the world of humans and found comfort in the forest, where they spent hours exploring, scavenging, and collecting — eventually discovering lichen. They began painting portraits of lichen’s wild, colorful, and fuzzy shapes.
In time, Ash learned that lichen is actually a composite organism, a mixture of two species — algae and fungi — working together to live. This idea originally challenged evolutionary theory so much that scientists didn’t believe it. But lichen had much more to teac...
A Podcast Turducken: With Wow in the World, Terrestrials and Circle Round
Lulu is hosting a holiday meal. She’s invited the characters from her extended kids podcast family - Wow in the World and Circle Round - for an epic kids podcast crossover special. It’s a potluck of stories and on the table is a turducken. Yes, a turkey stuffed with a duck stuffed with a chicken. Each show brings a wild story about one of these creatures. We learn about a chicken’s unexpected journey back home, a duck mystery in the middle of the Arctic Ocean and an indigenous folktale about how the turkey got its gobble, culmina...
The Hybrid: A Miracle Mule
In the game of life, every species is like an action figure. You got your dogs and your dung beetles, your bald eagles and your blueberries. And for a long time scientists believed it was pretty much impossible for those action figures to mix and make a new kind of action figure that was able to have its own babies (dog beetles? Baldberries? Nah). But, today we tell the story of a four-legged beast in Kentucky whose existence is upending scientific beliefs. If you want a big fat SPOILER, here it is: the creature in question is a mule...
The Night Flyer: How Bats sPOOkily Revive Forests
This Halloween, we’re going to the dark side. Deep in the darkest tropical forests, some of the world’s most elusive bats hang upside down in their winged sleeping bags. On a quest to find one of these flying mammals, Producerbud Ana ventures into a Puerto Rican forest and the back corridors of the American Museum of Natural History with Dr. Angelo Soto-Centeno. Why? Because while they may be scary and look kinda like Dracula, with their sharp fangs and beady eyes, these bats hold something crucial for humanity - the ability to repair entire ecosystems after some of t...
Maggies: The Healing Power of Baby Flies
Maggots are disgusting, right? Lulu has a hard time even saying the word maggot.
But in this episode, we’re asking you to join us in setting our “ick” aside. If you stick with us, we promise that you’ll go from thinking these bugs are the grossest things ever to actually kinda liking them. Maybe even loving them.
ER doctor Avir Mitra leads us down a rabbit hole of scientific discovery, explaining how these revolting critters have a history - and future - of saving human limbs and lives. Plus, a musical lesson in wound trea...
The Travelers: How Moon Trees Hide Among Us
In 1971, a red-headed, tree-loving astronaut named Stu ‘Smokey’ Roosa was asked to take something to the moon with him. Of all things, he chose to take a canister of 500 tree seeds. After orbiting the moon 34 times, the seeds made it back to Earth. NASA decided to plant the seeds all across the country and then… everyone forgot about them. Until one day, a third grader from Indiana stumbled on a tree with a strange plaque: "Moon Tree." This discovery set off a cascading search for all the trees that visited the moon across the United States. Science writer, and our ve...
The Builders: How Beavers Mend Our Planet
Few mammals have a bigger positive impact on the planet than the beaver. With its bright orange buck teeth, the creature is an expert engineer that brings life wherever it waddles and even fights fires. Our story begins in the Bronx river, once known as the “open sewer” of New York City. After some humans decide to clean it up, we meet one of the river’s residents - José the beaver. We learn about the US government parachuting beavers out of planes into the mountains. And finally head to California where we discover how one beaver family saved acres of...
The Unimaginable: How Gravitational Waves (Literally) Rocked Our World
Over a billion lightyears ago, in the darkness of outer space, a collision of black holes sent out a fleet of invisible waves that were headed right toward planet Earth. The waves were so powerful they could ripple spacetime but most people on Earth didn't believe the waves were real. SPOILER ALERT: The waves are called gravitational waves and…they are real! Astrophysicist Dr. Wanda Díaz Merced tells the story of what happened when they hit Earth in 2015 and how scientists came to learn to use senses beyond eyesight to detect the waves. We also learn from Dr. Sta...
PIZZA BFF
Pizza is one of the world’s most beloved foods. But as much as we love the way it tastes, the secrets of its ingredients are even yummier to discover. We explore the surprising sounds tomatoes make when they’re stressed, how wheat became integral to human survival and how mold is sometimes... delicious? This episode also features live tap-dancing, mind-melting cheese facts and what might be the Songbud’s catchiest song yet.
Special thanks to Little Island for having us. If you’re in NYC, go check them out. It’s free to wander around, there are hidden m...
The Horseshoe Crab's Secret
We’re back with an episode from the Radiolab archive. Horseshoe crabs have been around for a long time. They outlived the dinosaurs, survived all mass extinctions and witnessed the sprouting of the Earth’s first trees. The secret to their longevity? Their baby blue blood. Which has been saving both their lives and ours.
Lulu and Radiolab co-host, Latif Nasser, head to one of these bleeding facilities to learn how horseshoe crab blood became indispensable for modern medicine. And how this vampirish relationship humans have with the crabs might also be crucial to keeping them alive.

CHOWDA: A Souper Fascinating Tale
Today we’re bringing you a live episode we taped in Boston. It’s about clam chowder. We’re sharing it now because we’re doing ANOTHER LIVE SHOW at Little Island in NYC on August 6th + 7th - and that one’s about PIZZA! The show’s free. There will be pizza. Join if you’re in NYC (or make this the reason you visit). Check out all of our other performances here.
Lulu is a Bostonian who has never had clam chowder. Read that again. For some reason it always felt gross to her. So as an extreme...
The Sea Troll: An Everlasting Shark?
The Greenland shark is ugly. Its eyes look cloudy and dead. Its snout and fins are stubby. Its meat is poisonous. And that may be part of why most people have overlooked these sharks for so long. But there was a rumor circulating among Greenland villagers that this deepsea dweller could survive for centuries. Scientist John Steffensen went on a hunt to see if this was true and discovered that the Greenland shark can live for more than 500 years, making it the longest living vertebrate on the planet. Biologist Steve Austad explains how the shark avoids death for so...

We’re doing a bunch of LIVE SHOWS at Little Island in NYC on August 6th-7th. For free. Come join! Check out all of our performances here.
Today we’re bringing you an episode we taped LIVE at The Greene Space at WNYC. In a room filled with all types of critters — scorpions, hissing cockroaches, a tarantula named Isabel and our main star… the jumping spider. Entomologist and bug lover Dr. Sebastian Echeverri tells us all about his love for the jumping spider’s dance moves. Lulu and the audience learn about the creepy crawlies, pet them and t...
The Howler: The Dog Who Joined a Coyote Pack
On the outskirts of the Nevada desert, a young dog named Hades jumped his fence and ran away from home. His family lost hope, until one night, they saw Hades on the news. For almost seven months, he had been sleeping, eating and howling with a pack of coyotes.
We usually view coyotes as vicious, bloodthirsty beasts. But turns out, they can be pretty friendly. They form unlikely alliances with other animals all the time. They’re so flexible they can eat almost anything and live everywhere from open prairies to city streets, where they lurk unseen li...
The Invaders: Coquí Frogs Just Won't Die
Coquí frogs are synonymous with Puerto Rican identity. Residents of the island doze off to the high-pitched calls of coquís from dusk to dawn. There are even playlists of hours of coquí calls that lull listeners to sleep.
That’s why ProducerBud Ana, a proud Puerto Rican, was confused when she saw a poster calling for the eradication of coquí frogs at a Hawaiian airport. Turns out, residents of Hawaiʻi see coquís as a nuisance, disrupting not only their sleep but their precious ecosystems.
Listen as Ana explores how different islands can view these...
The Snow Beast: A Mystery Animal with Latif Nasser
Today we bring you a story stranger than fiction. In 2006, paleobiologist Natalia Rybczynski took a helicopter to a remote Arctic island near the North Pole, spending her afternoons scavenging for ancient treasures on the ground. One day, she found something the size of a potato chip. Turns out, it was a three and a half million year old chunk of bone. SPOILER ALERT BELOW.
Keep reading if you’re okay with us spoiling the surprise.
It’s a camel! Yes, the one we thought only hung out in deserts. Originally from North America, the camel trot...
The Windbreaker: Why Farts Make the World Go Round
Farts. Trouser trumpets. Sulfur squeaks. Or toots, as Lulu insists on calling them. Smelly bubbles of air we don’t like to talk about. But Songbud Alan and Producerbud Ana are not ones to shy away from the stinky sidelines of science.
First, they take us to a concert hall to meet a FARTchestra and hear how behind some of the world’s greatest works of art lies the power of farts. Next Dr. Juan Pablo Zhenlio takes us through the ecosystem of human digestion, meeting trillions of microscopic organisms to learn why we fart. Then we jump...
The Shadow Creature: Rats Who Save Human Lives
Rats have a bad reputation. They’ve been called evil, terrifying and wicked. The lowliest and most abominable of creatures. Songbud Alan felt the same way until he heard of one rat from Tanzania named Magawa. We meet Pendo, Magawa’s human friend and trainer, who wanted to train Magawa for a battlefield of sorts. A battle to save human lives.
You see, some countries have explosive landmines placed there during war. When the war is over, the landmines remain, meaning people continue to live in danger, afraid they might step on one. Pendo hoped to train Magaw...

The Bullseye: Treasure Hunt to Recursive Islands
Have you ever seen an island on a lake? On an island? On a lake? On another island? Josh Calder has. Working in a dusty room of a library, he first saw one on a map, and has been fascinated with these “recursive islands” ever since. Song bud Alan Goffinski takes us on a wild journey into these secret bullseyes hiding all over planet Earth. We learn from ecologist Elba Montes why recursive islands breed species found nowhere else on Earth, and thus are hotbeds of evolution.
Check out Josh Calder’s website for more island information and tr...
An Ocean in Space
BLAST OFF! NASA just sent a spacecraft to Europa, one of Jupiter's moons, and on the side of that spacecraft, they included a poem. Not just any poem — a poem by U.S. Poet Laureate Ada Limón. A poem that’s supposed to represent all of humanity to the universe. No biggie.
Host Lulu Miller opens up the floor to kids from all over the country to ask Limón and NASA scientist Cynthia Phillips questions about the mission, outer space, poetry and what a space slushie might taste like. Listen to find out the answers to all...
The Crystal Ball: Giant Honeybees Who Predict the Future
The honeybee. The ever-important pollinator for our plants is disappearing. Some call it the silence of the bees, others call it colony collapse disorder. Dr. Sammy Ramsey, our official bug correspondent, wondered, could it be due to parasites? And if so, how do we catch all of them? This question takes Dr. Sammy to the heart of a jungle in Bangladesh to look for overlooked honeybees impervious to parasites. The only problem? He can't find them. With help from a local guide named Babulall, he learns how the most overlooked bees could possibly save all the honey bees in...
The Stumpisode: The Wild World of Tree Stumps!
As dead as they seem, tree stumps are hubs of life and relationships. From stumps to snags, deadwood provides habitat for rodents, falcons, insects, and even humans! Stumps hold together the forest floor, give hunting perches to birds of prey in flatlands, prevent erosion and the encroachment of invasive species, usher in sunlight, provide nutrients, can be wells of renewable fuel, and hold onto stories human beings might have forgotten. Without these ghosts of trees past, nothing would be the same. Scottish author, artist and lover of tree stumps, Dr. Amanda Thomson, leads host Lulu Miller on a “tour de...
The Water Walker: One Surfer’s Epic Escape
The ocean can be a scary place: the waves are so strong, the water so deep. But surfer and illustrator AJ Dungo tells the story of an earthling who figured out how to walk on water and literally defy the rules of gravity. If you want a big SPOILER, here it is: It’s only human for the season, the grandfather of modern-day surfing, Duke Kahanamoku. Duke’s great grandniece, Heather Kina’u Paoa tells us about what Duke’s life was really like. We learn about the physics of surfing, and how surfing is an escape, not just on a spi...
The Trio: A Bald Eagle Love Story
High above the banks of the Mississippi river, a nest holds the secret life of one of America’s most patriotic creatures. Their story puzzles scientists, reinforces indigenous wisdom, and wows audiences, all thanks to a park ranger named Ed, and a well-placed webcam. If you want to spoil the mystery, here ya go: it’s a bald eagle. Actually, it’s three bald eagles. A mama bird and daddies make a home together for over a decade and give new meaning to our national symbol.
Learn about the storytellers, listen to music, and dig deeper into the sto...
The Guardian: Tsetse Fly Defenders
A singing entomologist, Dr. Sammy Ramsey, and a biologist with a knack for inventing things, Dr. Paul Mireji, tell us about one of the most fearsome animals on our planet. If you want a SPOILER of what it is, read on: It sucks our blood, spreads diseases; it's the tsetse fly. Both Sammy and Paul were afraid of this creature, but share the story of what can be gained by looking close at what scares you. In the case of the tsetse fly, we learn that these creatures give live birth, produce milk, protect entire ecosystems, and just might ho...
Vanished Moon!
The moon has disappeared. Ok, just kidding. Happy April Fool’s Day. But what if the moon actually vanished?
After songbud Alan saw a movie about stealing the moon, he wondered what would actually happen if the moon disappeared. He found the perfect person to talk to – Mika McKinnon who has a masters in disasters. We learn about eerie silences, ocean stench, hurricanes, and ecosystems in total flux.
Also a whole new season of Terrestrials is coming out soon! New stories, new songs and new wild beasts. Watch out for it on April 17th.

Gettin' Crabby
If someone calls you crabby, it’s not a compliment – they’re calling you grumpy, grouchy or snappy. But let’s reconsider this stain on the humble crab’s reputation. Look closely at a crab’s gnarled shell and you’ll see an incredible creature. Today, we bring you two very different crab stories. The first comes from former Radiolab producer Rachael Cusick about a woman who replicated the ocean to breed hermit crabs. Next, how crabs may hold a secret to surviving the chaos of the universe.
Radiolab was created by Jad Abumrad and is edited by Soren Wheel...
