Endorsed by His Holiness the Dalai Lama – ‘Balcombe vividly shows that fish have feelings and deserve consideration and protection like other sentient beings’

What’s the truth behind the old adage that goldfish have a three-second memory? Do fishes think? Can they recognize the humans who peer back at them from above the surface of the water? Myth-busting biologist and animal behaviour expert Jonathan Balcombe takes us under the sea, through streams and estuaries to the other side of the aquarium glass to answer these questions and more. He upends our assumptions, revealing that fish are far from the unfeeling, dead-eyed feeding machines so many of us assume them to be. They are, in fact, sentient, aware, social and even Machiavellian – in other words, rather 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. Teeming with insights and exciting discoveries, it offers a thoughtful appraisal of our relationships with fish and inspires us to take a more enlightened view of the planet’s increasingly imperilled marine life. What a Fish Knows will forever change how we see our aquatic cousins – the pet goldfish included.

‘Many of us have a soft spot for dolphins and whales, but Balcombe makes it embarrassingly clear how absolutely ignorant (and arrogant) we are when it comes to the vast world of our oceans and their inhabitants.’

"

‘As cogent, salutary and substantial a study of piscine behaviour as I have read in years…This is a book full of wonders.’

"

‘Eye-opening…What a Fish Knows is far more than a mass of would-you-believe-it facts, marvellously entertaining though they are...passionate and persuasive.’

"

‘Surprisingly, this compelling book is the first ever published that is devoted to fish behaviour.’

"

‘Remarkable.’

"

‘[A] sparkling exposition on “our underwater cousins”…[and] a compelling pitch for greatly expanding fish conservation.’

"

‘As ethologist Jonathan Balcombe notes in this engrossing study, breakthroughs are revealing sophisticated piscine behaviours. Balcombe glides from perception and cognition to tool use, pausing at marvels such as ocular migration in flounders and the capacity of the frillfin goby (Bathygobius soporator) to memorize the topography of the intertidal zone.’

"

‘Balcombe covers the waterfront, so to speak, from fish cognition and perception to their social structures and breeding practices, all the while drawing on a dizzying array of experiments and studies. In the hands of a lesser writer, the sheer weight of material could have overburdened the reader. But Balcombe’s prose is lively and clear, showcasing his gift for pithy sentences.’ 

"

‘With the vivacious energy of a cracking good storyteller, Balcombe draws deeply from scientific studies and his own experience with fish to introduce readers to them as sentient creatures that live full lives governed by cognition and perception…Balcombe makes a convincing case that fish possess minds and memories, are capable of planning and organizing, and cooperate with one another in webs of social relationships.’

"

‘[Balcombe] offers an enjoyable, surprising and sometimes gruesome exploration of the world of fish, written with clarity and humor and grounded in many scientific studies...The breadth and depth of his research and his enthusiastic storytelling may permanently alter how [readers] look at a pet goldfish or a can of sardines.’

"

‘Balcombe...wants people to care about fish as individuals, to think of them much as we would a pet cat or dog...This might sound like a fool’s errand. To most people, it probably seems doubtful that a fish has any sort of inner life, much less a rich one. But Mr. Balcombe builds a persuasive argument...through a compendium of fascinating anecdotes and scientific findings that illustrate the complexity and creativity of fish behavior. Dozens of startling revelations emerge, including playful marine fish riding bubbles to the top of an aquarium, elephantfish “singing” courtship duets using electric pulses, and parasite-picking cleaner fish engaging in convoluted “economic” interactions with their “clients.”’
