Discover the Astonishing Ways Animals Sense Their Surroundings and Uncover Hidden Realms

Animals inhabit a diverse range of environments and have evolved extraordinary senses to navigate and survive in their respective ecosystems. While humans primarily rely on our five basic senses -- sight, hearing, touch, taste, and smell -- to understand the world around us, animals possess an array of additional senses that unlock hidden realms beyond our perception. In this article, we delve into the astonishing ways in which animal senses go beyond human capabilities, revealing the hidden dimensions of the natural world.

1. Echolocation: A Sonic World

Imagine living in a world where your ability to see is limited or nonexistent. Bats, dolphins, and certain species of birds possess a remarkable skill known as echolocation, enabling them to perceive their surroundings through sound waves. By emitting high-pitched sounds and listening for echoes, these animals can create intricate mental maps, navigate through pitch darkness, and even detect prey with remarkable precision.

2. Magnetic Fields: A Sixth Sense

While humans may marvel at the way migratory birds flawlessly navigate over vast distances, the secret lies in their remarkable ability to sense the Earth's magnetic fields. Through tiny, specialized cells called magnetoreceptors, these birds can detect subtle changes in the planet's magnetic field, allowing them to orient themselves during migration routes and find their way home with unerring accuracy.

3. Infrared Vision: Spotting Hidden Heat

Reptiles, such as snakes and certain types of insects, have an exceptional ability to sense infrared radiation. This means they can detect the heat emitted by living organisms and even perceive temperature variations in their environment. By visualizing this hidden heat, these animals can locate prey, navigate through cluttered environments, and successfully camouflage themselves from potential threats.

4. Electric Fields: Sensing the Unseen

While electricity may remain undetectable to human senses, electric fish have evolved an extraordinary ability to sense and interpret weak electric fields surrounding them. These fish possess specialized electroreceptors that allow them to locate prey, navigate through dark waters, and even communicate with one another through electrical signals. By detecting distortions in these electric fields, they can decipher complex information about their environment.

5. Ultraviolet Perception: A Colorful World

While humans perceive a limited range of colors, many birds, insects, and even some reptiles can see ultraviolet light, revealing a whole new dimension of colors and patterns in the natural world. For example, ultraviolet perception helps bees identify nectar-rich flowers, birds to recognize potential mates based on plumage patterns invisible to us, and allows reptiles to communicate through subtle visual cues.

The diversity of animal sensory systems never ceases to amaze us. While our human senses provide a window into the world, animals possess a multitude of sensory abilities that enable them to perceive hidden dimensions and navigate their respective environments with unparalleled precision. Exploring and understanding the unique senses of animals not only enriches our knowledge, but also humbles us as we realize just how much is hidden from our perception.

Enter a new dimension—the world as it is truly perceived by other animals—from the Pulitzer Prize-winning, New York Times bestselling author of I Contain Multitudes.

“A stunning achievement, steeped in science but suffused with magic.”—Siddhartha Mukherjee, author of The Gene

The Earth teems with sights and textures, sounds and vibrations, smells and tastes, electric and magnetic fields. But every kind of animal, including humans, is enclosed within its own unique sensory bubble, perceiving but a tiny sliver of our immense world. 

In An Immense World, author and Pulitzer Prize–winning science journalist Ed Yong coaxes us beyond the confines of our own senses, allowing us to perceive the skeins of scent, waves of electromagnetism, and pulses of pressure that surround us. We encounter beetles that are drawn to fires, turtles that can track the Earth’s magnetic fields, fish that fill rivers with electrical messages, and even humans who wield sonar like bats. We discover that a crocodile’s scaly face is as sensitive as a lover’s fingertips, that the eyes of a giant squid evolved to see sparkling whales, that plants thrum with the inaudible songs of courting bugs, and that even simple scallops have complex vision. We learn what bees see in flowers, what songbirds hear in their tunes, and what dogs smell on the street. We listen to stories of pivotal discoveries in the field, while looking ahead at the many mysteries that remain unsolved. 

Funny, rigorous, and suffused with the joy of discovery, An Immense World takes us on what Marcel Proust called “the only true voyage . . . not to visit strange lands, but to possess other eyes.”
