A Natural History of Shells by Geerat J. Vermeij Pdf
From “one of the master naturalists of our time” (American Scientist), a fascinating exploration of what seashells reveal about biology, evolution, and the history of life Geerat Vermeij wrote this “celebration of shells” to share his enthusiasm for these supremely elegant creations and what they can teach us about nature. Most popular books on shells emphasize the identification of species, but Vermeij uses shells as a way to explore major ideas in biology. How are shells built? How do they work? And how did they evolve? With lucidity and charm, the MacArthur-winning evolutionary biologist reveals how shells give us insights into the lives of animals today and in the distant geological past.

The Book of Shells by M.G. Harasewych,Fabio Moretzsohn Pdf
Who among us hasn’t marveled at the diversity and beauty of shells? Or picked one up, held it to our ear, and then gazed in wonder at its shape and hue? Many a lifelong shell collector has cut teeth (and toes) on the beaches of the Jersey Shore, the Outer Banks, or the coasts of Sanibel Island. Some have even dived to the depths of the ocean. But most of us are not familiar with the biological origin of shells, their role in explaining evolutionary history, and the incredible variety of forms in which they come. Shells are the external skeletons of mollusks, an ancient and diverse phylum of invertebrates that are in the earliest fossil record of multicellular life over 500 million years ago. There are over 100,000 kinds of recorded mollusks, and some estimate that there are over amillion more that have yet to be discovered. Some breathe air, others live in fresh water, but most live in the ocean. They range in size from a grain of sand to a beach ball and in weight from a few grams to several hundred pounds. And in this lavishly illustrated volume, they finally get their full due. The Book of Shells offers a visually stunning and scientifically engaging guide to six hundred of the most intriguing mollusk shells, each chosen to convey the range of shapes and sizes that occur across a range of species. Each shell is reproduced here at its actual size, in full color, and is accompanied by an explanation of the shell’s range, distribution, abundance, habitat, and operculum—the piece that protects the mollusk when it’s in the shell. Brief scientific and historical accounts of each shell and related species include fun-filled facts and anecdotes that broaden its portrait. The Matchless Cone, for instance, or Conus cedonulli, was one of the rarest shells collected during the eighteenth century. So much so, in fact, that a specimen in 1796 was sold for more than six times as much as a painting by Vermeer at the same auction. But since the advent of scuba diving, this shell has become far more accessible to collectors—though not without certain risks. Some species of Conus produce venom that has caused more than thirty known human deaths. The Zebra Nerite, the Heart Cockle, the Indian Babylon, the Junonia, the Atlantic Thorny Oyster—shells from habitats spanning the poles and the tropics, from the highest mountains to the ocean’s deepest recesses, are all on display in this definitive work.

The Sound of the Sea: Seashells and the Fate of the Oceans by Cynthia Barnett Pdf
A Science Friday Best Science Book of the Year A Kirkus Reviews Best Nonfiction Book of the Year A Library Journal Best Science and Technology Book of the Year A Tampa Bay Times Best Book of the Year A stunning history of seashells and the animals that make them that "will have you marveling at nature…Barnett’s account remarkably spirals out, appropriately, to become a much larger story about the sea, about global history and about environmental crises and preservation" (John Williams, New York Times Book Review). Seashells have been the most coveted and collected of nature’s creations since the dawn of humanity. They were money before coins, jewelry before gems, art before canvas. In The Sound of the Sea, acclaimed environmental author Cynthia Barnett blends cultural history and science to trace our long love affair with seashells and the hidden lives of the mollusks that make them. Spiraling out from the great cities of shell that once rose in North America to the warming waters of the Maldives and the slave castles of Ghana, Barnett has created an unforgettable history of our world through an examination of the unassuming seashell. She begins with their childhood wonder, unwinds surprising histories like the origin of Shell Oil as a family business importing exotic shells, and charts what shells and the soft animals that build them are telling scientists about our warming, acidifying seas. From the eerie calls of early shell trumpets to the evolutionary miracle of spines and spires and the modern science of carbon capture inspired by shell, Barnett circles to her central point of listening to nature’s wisdom—and acting on what seashells have to say about taking care of each other and our world.
The beautifully written story of shells and their makers, and our relationships with them. Seashells are the sculpted homes of a remarkable group of animals: the molluscs. These are some of the most ancient and successful animals on the planet. But watch out. Some molluscs can kill you if you eat them. Some will kill you if you stand too close. That hasn't stopped people using shells in many ways over thousands of years. They became the first jewelry and oldest currencies; they've been used as potent symbols of sex and death, prestige and war, not to mention a nutritious (and tasty) source of food. Spirals in Time is an exuberant aquatic romp, revealing amazing tales of these undersea marvels. Helen Scales leads us on a journey into their realm, as she goes in search of everything from snails that 'fly' underwater on tiny wings to octopuses accused of stealing shells and giant mussels with golden beards that were supposedly the source of Jason's golden fleece, and learns how shells have been exchanged for human lives, tapped for mind-bending drugs and inspired advances in medical technology. Weaving through these stories are the remarkable animals that build them, creatures with fascinating tales to tell, a myriad of spiralling shells following just a few simple rules of mathematics and evolution. Shells are also bellwethers of our impact on the natural world. Some species have been overfished, others poisoned by polluted seas; perhaps most worryingly of all, molluscs are expected to fall victim to ocean acidification, a side-effect of climate change that may soon cause shells to simply melt away. But rather than dwelling on what we risk losing, Spirals in Time urges you to ponder how seashells can reconnect us with nature, and heal the rift between ourselves and the living world.
MAN and SHELLS Molluscs in the History by Riccardo Cattaneo-Vietti,Mauro Doneddu,Egidio Trainito Pdf
Since the Paleolithic age to the present, molluscs - which include squids, octopuses and a variety of shellfish - have featured in different facets of our history. Yet much of this detail is either unknown or underappreciated. From the shapes and patterns in their shells, to their culinary, medicinal and scientific value and from their depictions in literature and religions, mulluscs in general, and shellfish in particular, have fascinated mankind for millennia. Man and Shells is a treatise on molluscs in our natural history. Readers will traverse through the journey by demonstrating how these organisms have accompanied humans in arts and culture, in ancient religions, the myths that surround them, their role in commerce as in dyeing and as currency as well as in aquaculture and fishing, and much more. Man and Shells helps us to appreciate these creatures that continue to have an important yet little known place in the cultural evolution of man through the ages.
Following the trails of Hawai‘i’s snails to explore the simultaneously biological and cultural significance of extinction. In this time of extinctions, the humble snail rarely gets a mention. And yet snails are disappearing faster than any other species. In A World in a Shell, Thom van Dooren offers a collection of snail stories from Hawai‘i—once home to more than 750 species of land snails, almost two-thirds of which are now gone. Following snail trails through forests, laboratories, museums, and even a military training facility, and meeting with scientists and Native Hawaiians, van Dooren explores ongoing processes of ecological and cultural loss as they are woven through with possibilities for hope, care, mourning, and resilience. Van Dooren recounts the fascinating history of snail decline in the Hawaiian Islands: from deforestation for agriculture, timber, and more, through the nineteenth century shell collecting mania of missionary settlers, and on to the contemporary impacts of introduced predators. Along the way he asks how both snail loss and conservation efforts have been tangled up with larger processes of colonization, militarization, and globalization. These snail stories provide a potent window into ongoing global process of environmental and cultural change, including the largely unnoticed disappearance of countless snails, insects, and other less charismatic species. Ultimately, van Dooren seeks to cultivate a sense of wonder and appreciation for our damaged planet, revealing the world of possibilities and relationships that lies coiled within a snail’s shell.
