A New York Times Bestseller Do fishes think? Do they really have three-second memories? And can they recognize the humans who peer back at them from above the surface of the water? In What a Fish Knows, the myth-busting ethologist Jonathan Balcombe addresses these questions and more, taking us under the sea, through streams and estuaries, and to the other side of the aquarium glass to reveal the surprising capabilities of fishes. Although there are more than thirty thousand species of fish—more than all mammals, birds, reptiles, and amphibians combined—we rarely consider how individual fishes think, feel, and behave. Balcombe upends our assumptions about fishes, portraying them not as unfeeling, dead-eyed feeding machines but as sentient, aware, social, and even Machiavellian—in other words, much like us. What a Fish Knows draws on the latest science to present a fresh look at these remarkable creatures in all their breathtaking diversity and beauty. Fishes conduct elaborate courtship rituals and develop lifelong bonds with shoalmates. They also plan, hunt cooperatively, use tools, curry favor, deceive one another, and punish wrongdoers. We may imagine that fishes lead simple, fleeting lives—a mode of existence that boils down to a place on the food chain, rote spawning, and lots of aimless swimming. But, as Balcombe demonstrates, the truth is far richer and more complex, worthy of the grandest social novel. Highlighting breakthrough discoveries from fish enthusiasts and scientists around the world and pondering his own encounters with fishes, Balcombe examines the fascinating means by which fishes gain knowledge of the places they inhabit, from shallow tide pools to the deepest reaches of the ocean. Teeming with insights and exciting discoveries, What a Fish Knows offers a thoughtful appraisal of our relationships with fishes and inspires us to take a more enlightened view of the planet’s increasingly imperiled marine life. What a Fish Knows will forever change how we see our aquatic cousins—the pet goldfish included.

Another New York Times bestseller from the author of The Good Good Pig, this “fascinating…touching…informative…entertaining” (Daily Beast) book explores the emotional and physical world of the octopus—a surprisingly complex, intelligent, and spirited creature—and the remarkable connections it makes with humans. In pursuit of the wild, solitary, predatory octopus, popular naturalist Sy Montgomery has practiced true immersion journalism. From New England aquarium tanks to the reefs of French Polynesia and the Gulf of Mexico, she has befriended octopuses with strikingly different personalities—gentle Athena, assertive Octavia, curious Kali, and joyful Karma. Each creature shows her cleverness in myriad ways: escaping enclosures like an orangutan; jetting water to bounce balls; and endlessly tricking companions with multiple “sleights of hand” to get food. Scientists have only recently accepted the intelligence of dogs, birds, and chimpanzees but now are watching octopuses solve problems and are trying to decipher the meaning of the animal’s color-changing techniques. With her “joyful passion for these intelligent and fascinating creatures” (Library Journal Editors’ Spring Pick), Montgomery chronicles the growing appreciation of this mollusk as she tells a unique love story. By turns funny, entertaining, touching, and profound, The Soul of an Octopus reveals what octopuses can teach us about the meeting of two very different minds.

A New York Times Bestseller From world-renowned biologist and primatologist Frans de Waal, a groundbreaking work on animal intelligence destined to become a classic. What separates your mind from an animal’s? Maybe you think it’s your ability to design tools, your sense of self, or your grasp of past and future—all traits that have helped us define ourselves as the planet’s preeminent species. But in recent decades, these claims have eroded, or even been disproven outright, by a revolution in the study of animal cognition. Take the way octopuses use coconut shells as tools; elephants that classify humans by age, gender, and language; or Ayumu, the young male chimpanzee at Kyoto University whose flash memory puts that of humans to shame. Based on research involving crows, dolphins, parrots, sheep, wasps, bats, whales, and of course chimpanzees and bonobos, Frans de Waal explores both the scope and the depth of animal intelligence. He offers a firsthand account of how science has stood traditional behaviorism on its head by revealing how smart animals really are, and how we’ve underestimated their abilities for too long. People often assume a cognitive ladder, from lower to higher forms, with our own intelligence at the top. But what if it is more like a bush, with cognition taking different forms that are often incomparable to ours? Would you presume yourself dumber than a squirrel because you’re less adept at recalling the locations of hundreds of buried acorns? Or would you judge your perception of your surroundings as more sophisticated than that of a echolocating bat? De Waal reviews the rise and fall of the mechanistic view of animals and opens our minds to the idea that animal minds are far more intricate and complex than we have assumed. De Waal’s landmark work will convince you to rethink everything you thought you knew about animal—and human—intelligence.

A FINALIST FOR THE 2017 PEN/E. O. WILSON LITERARY SCIENCE WRITING AWARD LONGLISTED FOR THE ANDREW CARNEGIE MEDAL FOR EXCELLENCE A LIBRARY JOURNAL BEST SCIENCE BOOK OF THE YEAR “[A] curiously edifying book.” —The New York Times Book Review “With the taut suspense of a spy novel, Voigt paints a vivid world of murder, black market deals, and habitat destruction surrounding a fish that's considered, ironically, to be a good-luck charm.” —Discover “[An] immensely satisfying story, full of surprises and suspense....Things get weird fast.” —The Wall Street Journal A riveting journey into the bizarre world of the Asian arowana or “dragon fish”—the world’s most expensive aquarium fish—reveals a surprising history with profound implications for the future of wild animals and human beings alike. A young man is murdered for his prized pet fish. An Asian tycoon buys a single specimen for $150,000. Meanwhile, a pet detective chases smugglers through the streets of New York. Delving into an outlandish realm of obsession, paranoia, and criminality, The Dragon Behind the Glass tells the story of a fish like none other: a powerful predator dating to the age of the dinosaurs. Treasured as a status symbol believed to bring good luck, the Asian arowana is bred on high-security farms in Southeast Asia and sold by the hundreds of thousands each year. In the United States, however, it’s protected by the Endangered Species Act and illegal to bring into the country—though it remains the object of a thriving black market. From the South Bronx to Singapore, journalist Emily Voigt follows the trail of the fish, ultimately embarking on a years-long quest to find the arowana in the wild, venturing deep into some of the last remaining tropical wildernesses on earth. With a captivating blend of personal reporting, history, and science, The Dragon Behind the Glass traces our modern fascination with aquarium fish back to the era of exploration when intrepid naturalists stood on the cutting edge of modern science, discovering new and wondrous species in jungles all over the world. In an age when freshwater fish now comprise one of the most rapidly vanishing groups of animals on the planet, Voigt unearths a paradoxical truth behind the dragon fish’s rise to fame—one that calls into question how we protect the world’s rarest species. An elegant exploration of the human conquest of nature, The Dragon Behind the Glass revels in the sheer wonder of life’s diversity and lays bare our deepest desire—to hold onto what is wild.

Birds are astonishingly intelligent creatures. According to revolutionary new research, some birds rival primates and even humans in their remarkable forms of intelligence. In The Genius of Birds, acclaimed author Jennifer Ackerman explores the newly discovered brilliance of birds. As she travels around the world to the most cutting-edge frontiers of research—the distant laboratories of Barbados and New Caledonia, the great tit communities of the United Kingdom and the bowerbird habitats of Australia, the ravaged mid-Atlantic coast after Hurricane Sandy and the warming mountains of central Virginia and the western states—Ackerman not only tells the story of the recently uncovered genius of birds but also delves deeply into the latest findings about the bird brain itself that are shifting our view of what it means to be intelligent. Consider, as Ackerman does, the Clark’s nutcracker, a bird that can hide as many as 30,000 seeds over dozens of square miles and remember several months later where it put them, or the mockingbirds and thrashers, species that can store 200 to 2,000 different songs in a brain a thousand times smaller than ours. But beyond highlighting how birds use their unique genius in technical ways, Ackerman points out the impressive social smarts of birds. They deceive and manipulate. They eavesdrop. They give gifts. They kiss to console one another. They blackmail their parents. They alert one another to danger. They summon witnesses to the death of a peer. They may even grieve. This elegant scientific investigation and travelogue weaves personal anecdotes with fascinating science. Ackerman delivers an extraordinary story that will both give readers a new appreciation for the exceptional talents of birds and let them discover what birds can reveal about our changing world. Richly informative and beautifully written, The Genius of Birds celebrates the triumphs of these surprising and fiercely intelligent creatures. From the Hardcover edition.

“A bizarre collection of evolution tales . . . the weirder, the better.” —Entertainment Weekly A fascinating exploration of the awe-inspiring, unsettling ingenuity of evolution On a barren seafloor, the pearlfish swims into the safety of a sea cucumber’s anus. To find a meal, the female bolas spider releases pheromones that mimic a female moth, luring male moths into her sticky lasso web. The Glyptapanteles wasp injects a caterpillar with her young, which feed on the victim, erupt out of it, then mind-control the poor (and somehow still living) schmuck into protecting them from predators. These are among the curious critters of The Wasp That Brainwashed the Caterpillar, a jaunt through evolution’s most unbelievable, most ingenious solutions to the problems of everyday life, from trying to get laid to finding food. Join Wired science writer Matt Simon as he introduces you to the creatures that have it figured out, the ones that joust with their mustaches or choke sharks to death with snot, all in a wild struggle to survive and, of course, find true love.
