A thrilling tale of encounters with nature’s masters of biochemistry From the coasts of Indonesia to the rainforests of Peru, venomous animals are everywhere—and often lurking out of sight. Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world. Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out. Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated. Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

This book introduces the reader to herbal medicine; how to prepare and use herbal remedies. Includes notes on dosage and preparation and application of the remedies.

Many animal species have developed a deadly adaptation to thwart their predators: poison! Some infamous spiders and snakes are feared, and rightly so, for their toxic defenses. However, many other animals are just as deadly. In this fascinating volume, readers will find out the difference between poison and venom. They’ll learn about several creatures and the toxins they use to survive in the wild, such as the pufferfish, the poison dart frog, the cone snail, and the blue-ringed octopus. Beautiful color photographs, a graphic organizer, and fact boxes with stunning information augment this exciting volume.

Venom brings readers face to face with some of the most dangerous creatures on the planet, including jellyfish, snakes, and wasps, as it uncovers the story of venom. The book explores how venom is used for predation, defense, competition, and communication by an incredible diversity of species. It examines the unique methods that these species have evolved to create and deliver their deadly toxins. The book traces venom back to its origin in early jellyfish and sea anemones, and reveals how venoms have evolved dozens of times independently all across the animal kingdom since that time. And finally, it examines the relationships between these dangerous creatures and humans. Humans have not only learned to live with them, but also to benefit from them: scientists increasingly are harnessing the power of venom to create new drugs, treatments, and anti-venoms.

This book of photography represents National Geographic's Photo Ark, a major cross-platform initiative and lifelong project by photographer Joel Sartore to make portraits of the world's animals -- especially those that are endangered. His message: to know these animals is to save them. Sartore intends to photograph every animal in captivity in the world. He is circling the globe, visiting zoos and wildlife rescue centers to create studio portraits of 12,000 species, with an emphasis on those facing extinction. He has photographed more than 6,000 already and now, thanks to a multi-year partnership with National Geographic, he may reach his goal. This book showcases his animal portraits: from tiny to mammoth, from the Florida grasshopper sparrow to the greater one-horned rhinoceros. Paired with the prose of veteran wildlife writer Douglas Chadwick, this book presents an argument for saving all the species of our planet.
