About the author

Ed Yong is a science journalist who reports for The Atlantic, and is based in Washington DC.

His work appears several times a week on The Atlantic's website, and has also featured in National Geographic, the New Yorker, Wired, Nature, New Scientist, Scientific American, and many more. He has won a variety of awards, including the Michael E. DeBakey Journalism Award for biomedical reporting in 2016, the Byron H. Waksman Award for Excellence in the Public Communication of Life Sciences in 2016, and the National Academies Keck Science Communication Award in 2010 for his old blog Not Exactly Rocket Science. He regularly does talks and radio interviews; his TED talk on mind-controlling parasites has been watched by over 1.5 million people.

I Contain Multitudes, his first book, looks at the amazing partnerships between animals and microbes. Published in 2016, it became a New York Times bestseller, and was listed in best-of-2016 lists by the NYT, NPR, the Economist, the Guardian, and several others. Bill Gates called it "science journalism at its finest", and Jeopardy! turned it into a clue.

Ed cares deeply about accurate and nuanced reporting, clear and vivid storytelling, and social equality. He writes about everything that is or was once alive, from the quirky world of animal behaviour to the equally quirky lives of scientists, from the microbes that secretly rule the world to the species that are blinking out of it, from the people who are working to make science more reliable to those who are using it to craft policies. His stories span 3.7 billion years, from the origin of life itself to this month's developments in Congress. He makes terrible puns and regrets none of them. He has a Chatham Island black robin named after him.

Ed Yong's articles have long been a hit with my students. He has been my favorite science writer for years, and I really enjoy his clear explanations of complex topics mixed with humor and belief in his readers' intelligence. When I heard that he would be offering a young readers' edition of his adult book An Immense World, I knew I would be recommending it widely to both parents and children seeking nonfiction titles.

At this point, I have not yet read the adult version of this book and speak only of this edition. The subject matter is the worldview of various animals and how their senses affect how they understand and interact with the world around them.

The writing is at middle-grade level. The humor is younger than that, so adults might read-aloud to children who haven't yet built their reading skills to this level yet enjoy the subject matter. Like a textbook, An Immense World is broken into various short sections with vocabulary words bolded in the text and repeated in a word box at the end of the section. I especially liked that the units regarding color also color-coded the terms, visually reinforcing the message. Chapters are interspersed with "Ed's Field Notes," dropping us at various locales with scientists. These sections are written in a large, handwritten-style font. The book contains many illustrations. Altogether, the pages turn quickly, moving between exposition, field notes, illustrations, and vocabulary boxes. As an adult, I read the full book in two-and-a-half hours.

I believe many young readers will deeply enjoy this book. Prior to reading it, I would have misrepresented the level of humor in it because Yong's other writing has been so humorous. His wildly popular article on hagfish slime also perfectly hits the cool-meets-funny nexus that has excited so many of my students across different ages, and I was hoping this book would be doing precisely the same thing, but it's more neutrally informative. The book credits a couple other people for designing the Young Readers' Edition, and it was unclear to me if they were saying that Yong wasn't heavily involved in rewriting the book for a younger audience. The pedagogical choices that the team made were lovely.

This edition is for young readers, and I’d note it’s also nice for a (less young) reader who is interested but maybe not committed to picking up a ‘full’ science non-fiction volume.

This book might be a nice companion to Braiding Sweetgrass. While not explicit, I think it has neurodivergent connections.

“To perceive the world through other senses is to find splendour in the familiar, and the sacred in the mundane. … This ability to dip into the sensory worlds of other creature is our greatest sensory skill. … We may not ever know what it is to be an octopus, but at least we know that the experiences of an octopus are different from ours. By observing other animals, and through our curiosity and imagination, we can try to step into their worlds.”

A fascinating dive into mysteries of the animal world but this young readers edition keeps the information engaging for individuals not wanting to get too far into the weeds. I found it to include tons of interesting facts for not just young readers but adults as well. I think the adult edition would be too much for me, this was just right.

Super amazing! I learned a ton about animals!

[Robin Berman · Rating 5 out of 5]

Umwelt. I learned this word from this book. The book, and the word is about how every animal experiences the world and life in a different way.

The book is divided into sections describing the different senses like hearing, sight, smell. And some superpower senses like sensing magnetic fields and electric fields, and echolocation. It describes using senses both on land and underwater.
I enjoyed the "field notes" in each section which described scientists studying each topic on various animals in the wild.

Bees can sense the electric fields around flowers.

Notes-

1. Dogs smell better than humans because they have a bigger smell chamber behind their nose with more neurons capturing smells, and a larger olfactory bulb in their brain.
2. Snakes smell with their tongues, it's forked so they can sniff 2 different spots at once which can tell them which way prey went.
3. Seabirds, penguins, reef fish, and sea turtles track food by smelling for a gas called DMS - dimethyl sulfide. It's the scent of the "food rich sea" and they use it to find places where there's lots to eat. P. 27
4. Zebras are striped to keep away bloodsucking flies. The stripes confuse the flies.
5. Visual acuity is measured in cpd= cycles per degree. Higher cpd is better Visual acuity. Eagles and other birds of prey are the only animals with vision sharper than humans. P. 41
6. Some sea creatures (sea scallops) eyes can sense movement but don't see images. Some only have photo receptors not eyes (brittle stars).
7. Cats, deer, and others mammals have a tapetum in the eye- a reflective layer. It sends back any light that gets past the photoreceptors. P. 50
8. 2 types of photo receptors- cones allow eyes to see colors and rods are more sensitive, take over when little or no light. Cones only work in bright light.
9. Monochromats- animals that don't see colors, only black, white and shades of gray. Some have only rod cells in their eyes - sloths and armadillos. Other Monochromat animals only have 1 cone cell- Raccoons, sharks and whales. P. 57
10. Dichromats- have 2 kinds of cone cells and see limited range of colors. Dogs & horses.
11. Tricromats- see with 3 cone cells, see 100x more colors than most mammals. Humans & most primates. P. 59
12. Most animals can see UV light, Humans can't.
13. Fish communicate using secret UV patterns. P.63
14. Many birds have UV patterns in their feathers. So M & F look different from each other to them but the same to us, ie mockingbirds, Robins. P. 63
15. Tetrachromats have 4 cone cells, can see colors humans can't. Most birds have this. Hummingbirds see 100x more colors than humans can. Also reptiles, insects, freshwater fish. P. 65
16. There are a few female humans that are tetracromats! P. 65
17. Mantis shrimp are the only animals that can see circularly polarized light. P. 72
18. Nociceptors are neurons that detect harmful things, are activated by harmful stimuli. They are in our skin and other organs.
19. Nociception is the sensory process that detects damage, pain is the suffering that follows. P. 80
20. TRP channels are a group of proteins that are thermosensors - control how animals feel hot or cold.
21. Animals have senses that match the places they live.
22. 3 groups of snakes have heat sensitive organs just below its eyes called pits. They sense heat with them and find prey by detecting the heat in their prey like a warm rodent.
23. Touch depends on cells called mechanoreceptors- that respond to physical stimuli like touch or pressure.
24. Whiskers/vibrissae - where attached it's full of mechanoreceptors and nerves.
25. Harbor seals can track fish using their whiskers on their snout and eyebrows. Fish leave a hydrodynamic wake behind them as they swim. They are so faint we can't feel them, but seals can feel them almost 200 yards away. P. 123
26. Fish use their lateral lines- a network of touch sensors- to detect the flow of water around it as it swims, for coordination. Also used to match the speed and direction of its neighbors swimming in a school. Lateral lines gives fish an awareness of their surroundings.
27. Trichobothria- special hairs that are very sensitive to air movements, found on spiders and other animals.
28. Treehoppers use vibrations to communicate and to attract mates.
29. Elephants listen to underground vibrations with their feet.
30. Spiders are covered in thousands of "slit sensilla" - vibration detecting cracks which they use to sense vibrations flowing through whatever they're standing on. P. 145 An orb weaver sitting in the middle of its web can tell which vibrations are caused by wind, and which are from trapped prey. It can figure out its size and if it stops moving, the spider can find it by plucking the silk strings and feeling for the returning vibrations. The spider controls the webs strength, stiffness, tension and shape for its needs such as being able to feel smaller prey. The web is part of its sensory system, and it thinks with its web. P. 148
31. Many butterflies have ears on their wings to listen for predators/birds.
32. Birds find meaning in parts of their songs that we can't hear or pick out and our brains don't pay attention to. P. 166
33. Lowest frequency humans can hear is 20 Hz. Below that, sounds are infrasounds.
34. Fin whale calls can travel underwater for 13,000 miles. They are very low, 20 Hz.
35. Wild elephants use infrasounds to communicate.
36. Many animals use ultrasonic calls and hearing with frequencies higher than 20,000 Hz - the upper limit of human hearing.
37. Ultrasonic sounds- higher than 20,000 Hz
38. Dolphin sonar works over much larger ranges than bat sonar, because sound travels faster and farther in water. Sounds can move through things in water so dolphins can see inside objects and even through flesh to see organs and bones.
39. Around 350 fish species can produce electricity. They have special organs in some of their muscles and nerves which contain electrocyte cells. They control the flow of ions through the electrocytes creating electricity. The electric eel is one kind.
40. Most "electric" fish produce weak fields which they use for active electrolocation- to sense their surroundings and navigate around objects. They also use electricity to communicate with each other. Electric fields immediately appear and extend in every direction. Electric fish create images of its surroundings. The wraparound nature of electrolocation is most like touch, they act like they're touching their surroundings with electricity. P.202
41. Some electric fish turn their electric fields on & off to produce pulses. The shape of the pulses conveys information about a fish's identity.
42. Passive electroreception- some animals can sense electric fields from other organisms without creating their own electricity. Ex- sharks. All living things produce weak electric fields when underwater, sharks use this ability to find prey even if hiding or buried.
43. Hammerhead sharks heads, and sawfishes snouts "saws" are covered in electroreceptors. Echidnas and platypus have them too.
44. Earth's magnetic field- the Earth's core is solid iron sphere surrounded by metals like molten iron and nickel. The churning movements of that liquid metal turn the entire planet into a giant bar magnet. Earth's magnetic field wraps around the planet, from the South Pole to the North Pole, and its always there. It doesn't change over time or different seasons, isn't effected by weather. P. 210
45. Humans have used the Earth's magnetic field to navigate the globe for thousands of years using compasses. Other animals such as sea turtles, lobsters, songbirds others- have done the same for millions of years, *without * help, as if they have compasses built into their bodies-- this skill is *magnetoreception*-- the ability to sense Earth's magnetic field. It keeps migrating animals on track. P. 210
46. Animals don't produce magnetic fields and they only detect the Earth's magnetic field. They use it to navigate.
47. Sea turtles have TWO magnetic senses. A compass sense which tells them which direction to swim, and a GPS/mapping sense which enables them to know exactly where they are in the ocean. Ken Lohmann discovered this. P. 214
48. Magnetoreception is the sense we know the least about. Scientists don't know how animals sense magnetic fields.
49. Animals don't rely on magnetoreception alone. It's used along with other senses. Animals never use a sense on its own, they're multisensory creatures. P. 218
50. Magnetoreceptors- cells that detect magnetic fields.
51. Light and noise pollution are horrible for wildlife. We need to use less lights and reduce noise. Red lights are better than white and blue. Lights should be switched off when buildings and streets aren't in use. Sound absorbing barriers on land water can help reduce noise pollution.

A compelling and endlessly interesting book exploring how animals, insects and humans experience life through their individualized sensory "bubble." Each of us experiences the world differently through our senses, and that individualized sensory experience is known as an "umwelt." (Pronounced umvelt - the word is originally German/) This sensory experience varies not just between people, but drastically between species.

Written in a way that is understandable to young children, this young readers' adaptation of Ed Yong's novel is accomplishes the feat of accessibly explaining oftentimes complex and nuanced concepts. The illustrations and design of the book are visually appealing and break up the information into digestible sections.

I received an advanced reader copy of this book on Netgalley from Random House Children's. I will note that at first it was difficult to get any of my children to sit down and read it for any extended period of time, due to competing demands with the end of school and summer vacation. However, I knew they'd be interested once they got into it, and taking into consideration my own preference for nonfiction in audiobook format, after the book's publishing date I checked the audiobook out from my local library on Libby and played the book during a car trip as well as running errands around town.

Not only did I absolutely love it,but every single one of my kids ages 5-16 were completely silent and interested whenever the book was on. (This NEVER happens.) There was zero fighting in the car, even on a long car ride. My 11 year old, who wants to be an animal biologist one day, picked up the e-ARC and started reading it herself. I highly recommend trying the audiobook version if the print version doesn't work for your young readers. The narrator does an excellent job, and this book packed in a ton of extremely interesting and insightful information in a surprising small package

We've started re-reading the book (see previous paragraph: Mom will do anything to keep peace during long car rides). My 5-year-old, after listening to a few chapters yesterday, asked me, "Mom, does everyone have their own umwelt?" in the sweetest little voice. She gets it! she's interested, and it's starting wonderful conversations in our family about how we experience things, how we are different and similar, and has created a greater understanding in my children of other humans as well as animals. We've had discussions about how we each experience different senses (such as hearing or sight) differently, and we've all be very interested as we have learned about how animals and insects experience things, sometimes quite differently.

This book is unique, one-of-a-kind, and I feel it's interesting for anyone ages 5 to 105, or anyone who wants to learn more about humans and animals' sensory experience and perceptions, or more about the natural world.

Yong’s fascinating and personal foray into the world of animal senses (from 2022) reconfigured for a teen audience. Inspired by observations of his beloved corgi Typo, Yong wonders about how animals' perceptions of the world are different from our own and how we underestimate their experiences and abilities. He opens his book with an exploration of zoologist Jakob von Uxeküll’s 1909 theory of umwelt or sensory bubble, “the part of an animal’s surroundings that it can sense and experience. Your Umwelt could be completely different from that of another animal that’s standing right next to you.” Yong divides his book among the 5 well-known senses but also adds in others, including sensitivity to pain, heat, and vibration. The book’s full color digital illustrations give it an appealing and playful feel, which along with its widely spaced text and ample blank space, will make it accessible to middle school, high school, and even adult readers who might be intimidated by the original 464-page volume. The pages also have color-coded edges, making it easy to tell which sense we’re in, with each sense broken down on its introductory page into subsections. For example, chapter ten (“Living Batteries and Compasses: Electric and Magnetic Fields”) includes 4 sections: “Powerful Fish”, “The Various Uses of Voltage”, “They Know the Way”, and “The Mystery Sense Organ”. Young also inserts “Ed’s Field Notes” segments in which he visits scientists actively investigating gray whales, red-eyed tree frogs, and hermit crabs (just to name a few of his forays into the natural world). Of course, these interludes celebrate individual scientists, but they also allow readers to see a science journalist at work. Further enhancements include “Words to remember” lists, occasional color photos, and an index. This attractive and highly readable book, with its light touch and personal storytelling, will be an excellent option for nonfiction recreational readers as well as patrons doing research on zoology.

This book does a really fantastic job of translating the science-heavy text of an Immense World into kid-friendly language. There are lots of exclamation points, italics for emphasis, and bold used to indicate vocabulary words (with definitions provided, as in a middle-school textbook). There are also lots of illustrations. All of this combines to make what seems rather long into a very quick read.

My kiddo (11) actually listened to the audiobook of an Immense World with me (the original version) and then we came back to this one to see how they compared. His assessment: "This version has a LOT fewer words in it." He much preferred the original, and declined to continue reading this one after the first several chapters.

He is correct in his assesment - entire chapters of the original text get boiled down to just a few pages of occasionally over-excited language here. And of course, there are copious exclamation points. But, I think that's actually a good thing. My kiddo has always been a science nerd and at 11 is listening exclusively to science nonfiction meant for adults. For most kids, without his extensive background of science reading, this would be an exciting introduction into the worlds of different animals' senses.

It is a very easy read, with chapters only a few pages long and conversational language. I would recommend it to be read aloud to kids 6-9 who are interested in animals and science and for kids 10-14 to read themselves.

And of course the subject matter is fascinating. Ed Yong does a wonderful job making animal senses and the way they perceive the world seem fascinating and full of wonder.

Highly recommend to children, and also to teens and adults intimidated by the full text of the original.

4 1/2 stars. Why no sources or further reading. or were those just missing in the ARC?

We know the world through our senses, but that is a mere slice of reality. Exploring the perceptions of other animals reveals an unimagined and immense world. Twelve chapters explore animal senses, typically opening with the author interacting with an animal and the researcher who studies it, giving readers a powerful sense of how cutting edge much of this knowledge is. Each titled chapter is subdivided into helpfully specific sections. Well-crafted prose, plenty of metaphors, and jokey asides help create context, allowing readers to imagine what is beyond our range of experience. Color blocking, field notes, puzzlers, emboldened quotes, and words to remember help to break up the text. Photographs, line drawings and frequent full-color illustrations add interest, but the heavily digitized artwork seems discordantly bland in a work exploring diverse specificity. Back matter includes author's note, photo credits and index, but no sources or further reading. Review based on an ARC. Thanks to NetGalley and Bright Matter for a review copy in return for an unbiased review.

Having read and loved the original version, I wanted to check the young readers edition and I'm so happy I did. The adaptation is what a true young readers adaptation SHOULD look like (publishers take note because oftentimes it's never adapted and turns into a money grab but nothing is shifted including visuals or narrative for a younger audience). THIS, this is exactly the shift necessary to bring complex scientific information that also includes a touch of the magic and beauty of the animal world to a different audience. The information is one thing but the visual shift is another and this one is eye-catching and helpful: defining words, bolding information that should be remembered, and providing context clues and images to supplement the material.

High praise for this adaptation whether you ever read the original adult version or just this one, readers will learn about the five senses and beyond through animals and humans both past and present.

[Alexa Hamilton · Rating 5 out of 5]

What a phenomenal look at the world of animal senses. This is so well adapted for young readers, from the images to the way that they have pulled out vocabulary words. I think it's such a nice way to think about how everyone and everything sees the world differently. I learned an incredible amount about the way different animals might sense things. It reads very easily from beginning to end, but you could also pull out different sections to read and they would make sense alone. An incredible title. I'll have to go check out the adult edition just to see what else they include because this book feels complete.

[Mary · Rating 5 out of 5]

This book makes Yong's amazing work accessible to young people. It is also great for adult readers who may need something shorter or simpler. (Me!)
The immensity of the world, the way animals and plants interact with the world, and the limitations of human senses are explained in short chapters, colorful illustrations, highlighted/defined vocabulary, and Ed's field notes detailing some of the author's experiences.
While the book might appeal to some upper elementary readers, it is probably more useful for a middle school library.

An absolutely wonderful book; one of the top five of the year for me. If you love animals, nature, and cool scientific facts, you'll love it. But you may also like it if you're interested in questions of perception and philosophy. Highly recommended. The illustrations are good, too. There's plenty in this junior version to inspire and delight older teens and adults, though it's squarely aimed at middle graders. I'm not sure the adult version can top this, but I'm going to give it a read, anyway. ;)

Are you looking for a unique gift for someone who has not been into reading lately but just needs the right book to get back into it?

Ed Yong's young readers' edition of An Immense World will help them look at the world in a new and refreshing way - and they'll know a lot of cool things about how animals sense the world.

The format of the book is so appealing to readers who need or prefer to have text broken up into manageable chunks. The people who helped Ed make this young readers' edition are geniuses!

[Kristina Tutt · Rating 4 out of 5]

I had originally wanted to read the regular edition, but I’m glad I ended up reading this young readers edition instead. I thought it was a perfect example of accessible nonfiction. The illustrations were beautiful and complimented the text, but I would have liked to see some labeled diagrams and charts, too. I could see some of my upper elementary students enjoying this, but it’s probably best for middle school and up.

What an amazing book. I read it in a state of wonderment as I learned all the ways that the inhabitants of the natural world use a white variety of senses that we lack to know where they are, what’s around them and where to find their food and mates. This book not only opens dimensions of existence most humans are oblivious to but it also reminds us how important scientists are to understanding how to keep our planet earth healthy.

Wonderful Young Readers adaptation of Ed Yong's book. Honestly I think they improved the format of the original book, leaning into textbook-like qualities, such as definitions, illustrations and small example spotlights. These sections break up an otherwise dense text and make it appealing to a younger audience. The readability of this subject is high, and everything is broken down into digestible terms. Highly recommend for curious readers.

5 stars from both me and C - and honestly this young readers version was more my comprehension level than my attempt to listen to the adult version :) Animals are fascinating in so many ways that I can only barely begin to understand!

I learned so much! Author Ed Yong explores the sensory systems of animals, showing how they differ from our own and how much we miss when we think about animals based on our own sensory experiences. The Young Readers edition is beautifully illustrated and gets to the point - I learned plenty without drowning in scientific detail. Perfect for that nonfiction upper middle grade reader.

Well written and fun reading with loads of information I've never read before. I appreciate the authors ease of explaining very complicated concepts to younger readers without it feeling too simple. The liked the illustrations very much and Ed's Notebook is a nice way to break up the text.

I read the original version of An Immense World back in 2022 and was so excited when I learned this version for young readers was published. While I loved, and will always love the original, this is the version I will recommend to most people, young or old, due to its accessibility and length.

I used to be a middle school teacher, and one challenge was teaching the concept of worldview. The concept of umwelt (pronounced OOMvelt) makes me think of that same challenge, but applied to different species instead of different cultural backgrounds. How blind must we seem to a creature who is used to sensing ultraviolent light? How deaf we must seem to a creature who is used to hearing infrasonic sounds? This book made me feel such wonder about the world around me and through that, also think about my role in it.

This book earns a definitive five stars.

A very rich basic science content in the animal kingdom. It shouldn't be considered as a source of information for only middle grade but adults as well. Lots of animal senses wasn't really clear for me but they were explained smoothly in simple language. The graphics in the book was a complete joy.
