Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. We have hunted them for thousands of years and scratched their icons into our mythologies. They simultaneously fill us with waves of terror, awe and affection - yet we know hardly anything about them. Whales tend to only enter our awareness when they die, struck by a ship or stranded in the surf. They evolved from land-roaming, dog-like creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Yet despite centuries of observing whales, we know little about their evolutionary past. Palaeontologist Nick Pyenson takes us to the ends of the earth and to the cutting edge of whale research as he searches for the answers to some of our biggest questions about these graceful giants. His rich storytelling takes us deep inside the Smithsonian's unparalleled fossil collection, to frigid Antarctic waters, and to the arid desert of Chile, where scientists race against time to document the largest fossil whalebone site on earth. Spying on Whales is an illuminating story of scientific discovery that brings readers closer to the most enigmatic and beloved animals of all time.

"A palaeontological howdunnit...[Spying on Whales] captures the excitement of...seeking answers to deep questions in cetacean science." -Nature Called "the best of science writing" (Edward O. Wilson) and named a best book by Popular Science, a dive into the secret lives of whales, from their four-legged past to their perilous present. Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. They evolved from land-roaming, dog-sized creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and travel entire ocean basins. Whales fill us with terror, awe, and affection--yet there is still so much we don't know about them. Why did it take whales over 50 million years to evolve to such big sizes, and how do they eat enough to stay that big? How did their ancestors return from land to the sea--and what can their lives tell us about evolution as a whole? Importantly, in the sweepstakes of human-driven habitat and climate change, will whales survive? Nick Pyenson's research has given us the answers to some of our biggest questions about whales. He takes us deep inside the Smithsonian's unparalleled fossil collections, to frigid Antarctic waters, and to the arid desert in Chile, where scientists race against time to document the largest fossil whale site ever found. Full of rich storytelling and scientific discovery, Spying on Whales spans the ancient past to an uncertain future--all to better understand the most enigmatic creatures on Earth.
