An Immense World: How Animal Senses Reveal the Hidden Realms Around Us
Ed Yong
Top 10 Best Quotes
“It tells us that all is not as it seems and that everything we experience is but a filtered version of everything that we could experience.”
“The majesty of nature is not restricted to canyons and mountains. It can be found in the wilds of perception--the sensory spaces that lie outside our Umwelt and within those of other animals. To perceive the world through other senses is to find splendor in familiarity and the sacred in the mundane. Wonders exist in a backyard garden, where bees take the measure of a flower’s electric fields, leafhoppers send vibrational melodies through the stems of plants, and birds behold the hidden palates of rurples and grurples...Wilderness is not distant. We are continually immersed in it. It is there for us to imagine, to savor and to protect.”
“Senses that seem paranormal to us only appear this way because we are so limited and so painfully unaware of our limitations.”
“This concept is intuitive, and yet when we watch extremophiles, from emperor penguins braving the Antarctic chill to camels trekking over scorching sands, it’s easy to think that they are suffering throughout their lives. We admire them not just for their physiological resilience but also for their psychological fortitude. We project our senses onto theirs and assume that they’d be in discomfort because we’d be in discomfort. But their senses are tuned to the temperatures in which they live. A camel likely isn’t distressed by the baking sun, and penguins probably don’t mind huddling through an Antarctic storm. Let the storm rage on. The cold doesn’t bother them, anyway.”
“There is a wonderful word for this sensory bubble—Umwelt. It was defined and popularized by the Baltic-German zoologist Jakob von Uexküll in 1909. Umwelt comes from the German word for “environment,” but Uexküll didn’t use it simply to refer to an animal’s surroundings. Instead, an Umwelt is specifically the part of those surroundings that an animal can sense and experience—its perceptual world. Like the occupants of our imaginary room, a multitude of creatures could be standing in the same physical space and have completely different Umwelten. A tick, questing for mammalian blood, cares about body heat, the touch of hair, and the odor of butyric acid that emanates from skin. These three things constitute its Umwelt. Trees of green, red roses too, skies of blue, and clouds of white—these are not part of its wonderful world. The tick doesn’t willfully ignore them. It simply cannot sense them and doesn’t know they exist.”
“A scientist's data are influenced by the questions she asks, which are steered by her imagination, which is delimited by her senses. The boundaries of our own Umwelt corral our ability to understand the Umwelten of others.”
“A moth will never know what a zebra finch hears in its song, a zebra finch will never feel the electric buzz of a black ghost knifefish, a knifefish will never see through the eyes of a mantis shrimp, a mantis shrimp will never smell the way a dog can, and a dog will never understand what it is to be a bat. We will never fully do any of these things either, but we are the only animal that can try.”
“how all animals see—using light-sensitive proteins that are actually modified chemical sensors. In a way, we see by smelling light.”
“To perceive the world through other senses is to find splendor in familiarity, and the sacred in the mundane.”
“This smorgasbord of eyes brings with it a dizzying medley of visual Umwelten. Animals might see crisp detail at a distance, or nothing more than blurry blotches of light and shade. They might see perfectly well in what we’d call darkness, or go instantly blind in what we’d call brightness. They might see in what we’d deem slow motion or time-lapse. They might see in two directions at once, or in every direction at once. Their vision might get more or less sensitive over the span of a single day. Their Umwelt might change as they get older. Jakob’s colleague Nate Morehouse has shown that jumping spiders are born with their lifetime’s supply of light-detecting cells, which get bigger and more sensitive with age. “Things would get brighter and brighter,” Morehouse tells me. For a jumping spider, getting older “is like watching the sun rising.”
