“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.
