Book Description
This richly illustrated book presents the diversity and natural history of sea snail groups. By integrating aspects of morphology, ecology, evolution and behaviour, it describes how each group copes with problems of defence, locomotion, nutrition, reproduction and embryonic development. First come general characteristics of the Mollusca, to which snails belong; and next, characteristics by which snails (Gastropoda) differ from other molluscs. Then a broad, panoramic view of all major sea snail groups, from the primitive to the more advanced, is presented, including both the more abundant and some remote ones of special interest. In detailing primitive sea snails, first limpets (Patellogastropoda) are described, followed by brush snails (Vetigastropoda: top-shells, turbans and allies) and nerites (Neritimorpha), a small group with remarkably high variation in shell colour and in habitats. In looking at advanced-snails (Caenogastropoda), it details the herbivorous grazers and filter-feeders and the many voracious predators, some which use venomous darts. The book also covers sea slugs (Opisthobranchia), which have shifted from mechanical to chemical defence; some are herbivores, some use their food to harness solar energy, others are predators that gain stinging cells and poisonous compounds from their food. In addition, readers will learn about aspects of sea snails in human culture, including use as sacred artefacts and objects of magic and money, as a source of the royal and sacred dyes of purple and blue and as holy ceremonial trumpets. The text, in which scientific terms are accompanied by parallel common ones, is accompanied by over 200 illustrations (mostly in colour). This comprehensive, insightful portrait of sea snails will appeal to marine biologists, zoology lecturers and students, biology teachers, field-school instructors, nature reserve wardens, amateur naturalists, as well as to lecturers and learners of human culture.

Book Description
The snails found living on rocky sea shores are among the most rewarding invertebrate animals to study. Species such as dog-whelks, topshells and winkles are easy to find, capture, identify, measure and mark. This book provides a key to common species, background ecology, an overview of rocky shore habitats and the techniques required for anyone to study this fascinating and accessible fauna.

Book Description
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.

Book Description
So attached was the author Patricia Highsmith to snails that they became her constant travelling companions. Often hidden in a large handbag, they provided her with comfort and companionship in what she perceived to be a hostile world. Theirs was perhaps an unusual relationship; for most of us the tentacled snail with his sticky trail might be a delicious treat served up in garlic butter but certainly not an affectionate pet. As well, for many a gardener, opinions on the snail and slug (which is a just a snail without a shell) have been shaped by the harm they inflict on vegetable plants and seedlings. With Snail, Peter Williams wishes to change our perspectives on this little but much-maligned creature. Beginning with an overview of our relationship with snails, slugs, and sea snails, Williams moves on to examine snail evolution; snail behavior and habitat; snails as food, medicine, and the source of useful chemicals and dyes; snail shells as collectible objects; and snails in literature, art, and popular culture. Finally, in this appreciative account of the snail, Williams offers a plea for a reconsideration of the snail as a dignified, ancient creature that deserves our respect. Containing beautiful illustrations and written in an approachable, informal style, Snail will help readers get beyond the shell and slime to discover the fascinating creature inside.
