About this book

Slugs and snails are part of the great Phylum Mollusca, a group that contains creatures as different as the fast-moving squid of the oceans and the sedentary clams, cockles and mussels. The largest group, however, are the gastropods, animals originally with a single foot and, arguably, a single coiled shell.

They are the only group of molluscs to have representatives living on land as well as in the sea and freshwaters. Slugs and Snails is about those gastropods that made that transition to a terrestrial existence, the slugs and snails that live on land. With a few exceptions, they have attracted less attention than their aquatic relatives, but the more we know about them, the more extraordinary they appear.

For creatures living on land they are bizarre. Snails carry round with them a huge weight of shell. Both snails and slugs move slowly relative to potential enemies and most are not well camouflaged. Their wet bodies are at the mercy of dry weather and their movement is apparently very wasteful of energy and water. Despite this, they are found from the tundra through to deserts, and on all continents apart from Antarctica. They have reached the most remote oceanic islands and undergone amazing evolutionary radiations there. As pests, they are remarkably tenacious and hard to control. They have evolved to span a huge range of size. Through all this, they have retained a set of shapes and structures very similar to those of their marine relatives and ancestors. Furthermore it is evident that the emergence onto land happened not once, but several times, originating in different groups of aquatic snails.

In this long-anticipated New Naturalist volume, Robert Cameron introduces us to this remarkable group of gastropods, telling us the stories of the snail familiar to all British and many other readers, the garden snail, and of the giant African snail, introduced into many tropical countries, as well as providing a comprehensive natural history of slugs and snails of the British Isles specifically. Snails can be and have been used to explore important ideas in evolutionary biology, in biogeography and in ecology, and Cameron draws out these explorations, looking specifically at the role of evolution in determining how our understanding of snails has developed.

"[...] I can unhesitatingly recommend this book. It is extremely thorough in its coverage and is an engrossing read, packed with an amazing range of fascinating information. It is generously illustrated with numerous pictures, illustrations and charts. The coverage is so wide that even specialists will undoubtedly discover much new material. This ground-breaking volume should remain a standard work on the natural history of snails and slugs for many years."
