Slugs and Snails (Collins New Naturalist Library, Book 133)
Slugs and snails are part of the great Phylum Mollusca, a group that contains creatures as varied as the fast-moving squid or the sedentary clams, cockles and mussels. The largest group, however, are the gastropods, animals originally with a single foot and a single coiled shell.
Snail
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-malig...

Keys for the Identification of Land Snails in the British Isles
Detailing all of the species of land snails to be found in the British Isles, this guide covers topics such as identification, collection and preservation, as well as detailing the internal characters and reproductive systems of the gastropods.
Snails
Snails are nearly sessile organisms. They are unable to respond to changes in the environment by escaping. Consequently, snails have to have a "flexible" phenotype which enables variable morphological and behavioural adaptations. In this book, the authors present topical research in the biology, ecology and conservation of snails including: neurotransmitters, benthic diatoms and metamorphosis in marine snails; parasitism as a factor in the morphology and behaviour of freshwater snails; cone snail biology; the role of the transcriptional regulator snail in cancer biology; the importance of moisture in the activity patterns of the arid-dwelling land snail and the adaptive flexibility of the pulmonate's brain.
Freshwater Snails Of Africa And Their Medical Importance
The first half of this book is primarily a systematic survey of the snails, beginning with glossaries, keys for identification to genera and a checklist of species. This is followed by a synopsis of species, with brief notes on ecology, distribution and parasites. Relationships are then described between snails and schistosomes and with other paras
