Illustrations and descriptive information on all living marine mollusks in the families Conidae and Conolithidae along with their taxonomic placement

Conus is the largest genus of animals in the sea, occurring throughout the world's tropical and subtropical oceans and contributing significantly to marine biodiversity. The shells of these marine mollusks are prized for their amazing variety and extraordinary beauty. The neurotoxic venoms they produce—injected by a hollow, harpoon-like tooth into prey animals that are then paralyzed and swallowed whole—have a range of pharmaceutical applications, from painkillers to antidepressants. This beautifully illustrated book identifies 53 valid species of the southeastern United States and the Caribbean, a region that supports a diverse but taxonomically challenging group of Conus. Introductory chapters cover the evolution and phylogeny of the genus, and notes on methodology are provided. Detailed species accounts describe key identification features, taxonomy, distribution, ecology, toxicology, life history, and evolutionary relationships. The book includes more than 2,100 photos of shells on 109 splendid color plates; more than 100 additional photos, many depicting live animals in color; and 35 color distribution maps. Identifies 53 valid species—the first reassessment of western Atlantic Conus in more than seventy years Features more than 2,100 photos of shells on 109 color plates Blends the traditional shell-character approach to identification with cutting-edge shell and radular tooth morphometrics and molecular genetic analyses Includes color images of live animals as well as color distribution maps

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 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.

In this astonishingly assured, exquisitely crafted debut collection, Anthony Doerr takes readers from the African coast to the suburbs of Ohio, from sideshow pageantry to harsh wilderness survival, charting a vast and varied emotional landscape. Like the best storytellers, Doerr explores the human condition in all its manifestations: metamorphosis, grief, fractured relationships, and slowly mending hearts. Most dazzling is Doerr's gift for conjuring nature in both its beautiful abundance and crushing power. Some of his characters contend with tremendous hardship; some discover unique gifts; all are united by their ultimate deference to the mysteries of their respective landscapes.

Mollusks have been important to humans since our earliest days. Initially, when humans were primarily interested in what they could eat or use, mollusks were important as food, ornaments, and materials for tools. Over the centuries, as human knowledge branched out and individuals started to study the world around them, mollusks were important subjects for learning how things worked. In this volume, the editors and contributors have brought together a broad range of topics within the field of malacology. It is our expectation that these topics will be of interest and use to amateur and professional malacologists.

Located where the Atlantic Ocean, Gulf of Mexico, and Caribbean Sea converge, the Florida Keys are distinctive for their rich and varied marine fauna. The Keys are home to nearly sixty taxonomic families of bivalves such as clams and mussels--roughly half the world's bivalve family diversity. The first in a series of three volumes on the molluscan fauna of the Keys and adjacent regions, Seashells of Southern Florida: Bivalves provides a comprehensive treatment of these bivalves, and also serves as a comparative anatomical guide to bivalve diversity worldwide. Paula Mikkelsen and Rüdiger Bieler cover more than three hundred species of bivalves, including clams, scallops, oysters, mussels, shipworms, jewel boxes, tellins, and many lesser-known groups. For each family they select an exemplar species and illustrate its shell and anatomical features in detail. They describe habitat and other relevant information, and accompany each species account with high-resolution shell photographs of other family members. Text and images combine to present species--to family-level characteristics in a complete way never before seen. The book includes fifteen hundred mostly color photographs and images of shells, underwater habitats, bivalves in situ, original anatomical and hinge drawings, scanning electron micrographs, and unique transparent--shell illustrations with major organ systems color-coded and clearly shown. Seashells of Southern Florida: Bivalves is the most complete guide to subtropical bivalves available. It is an essential tool for students and teachers of molluscan diversity and systematics, and an indispensable identification guide for collectors, scuba divers, naturalists, environmental consultants, and natural-resource managers.
