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.

Life is beautiful, ruthless, and very, very strange. In the evolutionary arms race that has raged on since life began, organisms have developed an endless variety of survival strategies. From sharp claws to brute strength, camouflage to venom—all these tools and abilities share one purpose: to keep their bearer alive long enough to reproduce, helping the species avoid extinction. Every living thing on this planet has developed a time-tested arsenal of weapons and defenses. Some of these weapons and defenses, however, are decidedly more unusual than others. In Strange Survivors, biologist Oné R. Pagán takes us on a tour of the improbable, the ingenious, and the just plain bizarre ways that creatures fight for life. Inside this funny, fascinating field guide to nature’s most colorful characters, you’ll meet killer snails, social bacteria, and an animal with toxic elbows. But Strange Survivors is more than a collection of curiosities—it is a love letter to science and an argument for the continuing relevance of this evolutionary battle as we face the threat of resistant bacteria and the need for novel medical therapies. Whether discussing blood-thinning bats and electric fish or pondering the power of cooperation, Pagán reveals the surprising lessons found in some of life’s natural oddities and how the tactics they employ to live might aid our own survival.

Humans tend to think that we are unique in our intelligence, social skill and depth of emotion. We tend to forget that we are animals too, and if we’re paying attention, we might see a bit of ourselves in the sheer variety of species, with their myriad behaviors, survival skills, social and communication systems and other traits. For example, it might seem baffling that a certain African termite would build mud homes that can reach 18 feet tall – until we find out that they're not the latest style in insect McMansions, but rather the height works for climate control. In this eBook, we gather recent research on animal behavior, including surprising discoveries of how animals think and feel, from man’s best friend to some of the earth’s oddest creatures. In examining the act of mourning, for instance, mounting evidence indicates that species from dolphins to elephants to cats and dogs experience grief over the loss of loved ones. Killer whales appear to be splitting into separate species over, of all things, cultural differences in food acquisition – currently a hot button issue for our own species. The animal kingdom teems with secret stories of strange and fascinating lives, some of which can help remind us what it means to be human.

The zombie has had a bit of a renaissance over the last decade. It seems like zombies are everywhere. From recent films like World War Z to popular TV shows like The Walking Dead, we’ve reached peak zombie saturation in American culture. Communities throughout the country hold zombie runs and races. In 2016 the first zombie-proof house was built, complete with concrete walls that move over the structure so that it’s completely sealed. Even the Centers for Disease Control and Prevention compiled a preparedness guide “in case” of a zombie apocalypse. So what’s driving the zombie obsession in American culture? Where did the fear of this creature originate? In this eBook, The Real Zombies of Nature, we look at the myth of the zombie versus real instances of zombification in the natural world and engage in some scientific speculation about what would happen if myth ever became reality.
