The present book aims, in contrast to other volumes, not to represent all molluscan species living in European seas (i.e. from the Canary Islands and the Azores in the (South-) West, to Scandinavia in the North and the entire Mediterranean (sometimes the Black Sea) and the Baltic Sea to the East). Instead, this book should enable interested amateurs as well as zoologists and oceanographers to identify common species which can easily be found without costly technical equipment. It however also wants to provide an overview about the molluscan fauna of the European seas. The book is intended to encourage interested amateurs and also students of biology to become familiar with Mollusca, a fascinating animal group. A scientific shell collection or a collection of mollusc photographs may be the basis of such an interest. Considering that more and more species - also in the oceans - are becoming endangered or even disappear for ever, experts who know about these species and their biology are badly needed. The present book is intended as a "field identification guide", to be applied during excursions and collection trips and should therefore enable the quick identification of mollusc material. Indeed, the vast majority of molluscan findings, if they are not of deep-water origin, should be easily identified at least down to genus level. General and more specific literature is listed at the end of this volume. The book contains more than 1500 species of all molluscan groups (i.e. Polyplacophora, Gastropoda, including Nudibranchs, Bivalvia and Cephalopoda) which are described and discussed in detail and of which about 1400 are pictured usually with several specimens on 350 colour plates. Besides this, different topics concerning responsible collecting, ecology, biology, protection of nature and many more are presented in short essays. [9783948603007].

The northern Adriatic is in turmoil. Harmful human impact has caused die-offs and drastic changes in the number of species and their structure, with many things changing from bad to worse. However, in marine protected areas and other localities that still are in an almost pristine state, one finds magnificent microworlds, animal communities of the seafloor, exhibiting a wealth of shapes, colours, and life habits masterpieces of nature. To the human eye, these species' survival tricks range from decent to weird. They are small but excellent, difficult to find, and a revelation once they are on camera. The present book has been created to celebrate their beauty and tell their stories: How does "natural engineering" allow for their survival with the help of fans, filters, tentacles, pumps, and slime nets? How can some of them hide in plain sight while others bore into solid rock? What do they do to find mates? This book is meant as an advertisement for those little beauties and their diversity. In an ocean thrown out of balance by human activities, they are in limbo and deserve protection. Guardians wanted! The authors of this book, a group of dedicated naturalists, underwater photographers, and marine researchers who have watched the northern Adriatic benthic communities for decades, have thus reached deep into their photo collections and into their accumulated knowledge about marine organisms, and present their favourite photos, their favourite tales with the hope that the readers will fall in love with the splendid miniature communities at the bottom of the sea.
