They are found in a wide variety of easily accessible terrestrial microhabitats, such as soil, leaf litter, mosses and lichens. They are also commonly found in freshwater and marine communities. The Biology of Tardigrades is the only modern comprehensive account of marine and freshwater tardigrades. It contains the first taxonomic review for over a decade in addition to covering every aspect of their biology. The Biology of Tardigrades is highly illustrated and includes an extensive list of references for further reading as well as a glossary. This book will be particular interest to all undergraduates, postgraduates, lecturers and research workers who are concerned with invertebrates, but will also provide absorbing reading material for all those who are involved in the field of evolutionary zoology.
