Short description Annelids offer an array of experimentally accessible features, making them a rich experimental subject across the biological sciences, including evolutionary development, neurosciences and stem cell research. This volume introduces the Annelids and their utility in evolutionary developmental biology, neurobiology, and environmental/ecological studies, including extreme environments. It demonstrates the variety of fields in which Annelids are already proving to be a useful experimental system. It is invaluable to researchers, as it is the only book to describe the utility of annelids as a research model.
