Jellyfish have been swimming in our oceans for well over half a billion years, longer than any other animal that lives on the planet. They make a venom so toxic it can kill a human in three minutes. Their sting—microscopic spears that pierce with five million times the acceleration of gravity—is the fastest known motion in the animal kingdom. Made of roughly 95 percent water, some jellies are barely perceptible virtuosos of disguise, while others glow with a luminescence that has revolutionized biotechnology. Yet until recently, jellyfish were largely ignored by science, and they remain among the most poorly understood of ocean dwellers. More than a decade ago, Juli Berwald left a career in ocean science to raise a family in landlocked Austin, Texas, but jellyfish drew her back to the sea. Recent, massive blooms of billions of jellyfish have clogged power plants, decimated fisheries, and caused millions of dollars of damage. Driven by questions about how overfishing, coastal development, and climate change were contributing to a jellyfish population explosion, Juli embarked on a scientific odyssey. She traveled the globe to meet the biologists who devote their careers to jellies, hitched rides on Japanese fishing boats to see giant jellyfish in the wild, raised jellyfish in her dining room, and throughout it all marveled at the complexity of these alluring and ominous biological wonders. Gracefully blending personal memoir with crystal-clear distillations of science, Spineless is the story of how Juli learned to navigate and ultimately embrace her ambition, her curiosity, and her passion for the natural world. She discovers that jellyfish science is more than just a quest for answers. It’s a call to realize our collective responsibility for the planet we share.
Cod, Mark Kurlansky’s third work of nonfiction and winner of the 1999 James Beard Award, is the biography of a single species of fish, but it may as well be a world history with this humble fish as its recurring main character. Cod, it turns out, is the reason Europeans set sail across the Atlantic, and it is the only reason they could. What did the Vikings eat in icy Greenland and on the five expeditions to America recorded in the Icelandic sagas? Cod, frozen and dried in the frosty air, then broken into pieces and eaten like hardtack. What was the staple of the medieval diet? Cod again, sold salted by the Basques, an enigmatic people with a mysterious, unlimited supply of cod. As we make our way through the centuries of cod history, we also find a delicious legacy of recipes, and the tragic story of environmental failure, of depleted fishing stocks where once their numbers were legendary. In this lovely, thoughtful history, Mark Kurlansky ponders the question: Is the fish that changed the world forever changed by the world's folly?
