Students and naturalists are not only interested in which species live on the seashore but also about their biology. How does a particular species reproduce? What is its life cycle? A Student's Guide to the Seashore is a unique, concise, illustrated guide to both the biology and identification of over 600 common and widespread shore animals and plants. In this new edition, for the first time, simple keys are included to allow accurate identification, and each species is beautifully illustrated by the author's line drawings. Together with concise summaries of diagnostic features, and notes on biology, this is the first comprehensive guide to the seashore giving a fascinating insight into the diversity and complexity of life on the shore. An extensive glossary of scientific terms and complete bibliography ensure that this book will be the premier biological text and identification guide for many years to come.

In this Special Issue, we address the state of the art of the systematics of the main annelid groups and the improvements in the diversity they hold, with special emphasis on the latest discoveries in well-studied areas, expeditions to unsurveyed areas or environments, or the use of novel techniques that allow for the improvement of biodiversity knowledge. We are hoping that this Special Issue will provide a platform facilitating a review of current knowledge on the subject, identifying current research problems, as well as indicating directions and research trends for the future.

In July 2001 experts from all around the world met in Reykjavik, Iceland to discuss various issues of polychaete biology. In particular the latest developments in cladistic inference of polychaete phylogeny were presented. Some studies applied recent molecular techniques, revealing unknown genetic relationships between the different families of polychaetous annelids. This volume is of interest to specialists and students seeking an introduction to the latest developments in the field of systematics and ecology of polychaetous annelids. This book is one in a series presenting results from the International Polychaete conferences.

Contains 67 original papers by nearly 100 of the world’s leading specialists. Together with abstracts and literature references for 37 presentations not represented by papers, this volume provides complete coverage of the Conference and a comprehensive overview of modern research on the polychaete annelids, one of the most important groups of marine invertebrates and constituents of marine benthos. Taxonomic and subject indices of all papers and abstracts provide ready access to the contained information. Richly illustrated, this book is provided with numerous line drawings, and photomicrographs, electron micrographs. Over 60 taxa are newly described or reassigned, and detailed reviews, revisions or redescriptions are provided for five families, one subfamily and numerous genera and species, with many illustrations of new and redescribed taxa and a pictorial key to the maglonids of Thailand.

The peanut-shaped sternaspid polychaetes have been known since 1760 when Plancus named them as Mentula cucurbitacea marina. Sternaspids are common and abundant in soft bottoms. Some authors suggested that only one species should be recognized, whereas others regard a few species very widely distributed and variable depths. Delineating species was problematic; the ventro-caudal shield was disregarded or barely used for identifying species. In this contribution the ventral shield is evaluated and its diagnostic potential is confirmed. The revision of Sternaspis is based upon type or topotype materials. Sternaspid body, introvert hooks and shield show three distinct patterns: two genera have 7 abdominal segments and tapered introvert hooks, and one genus has 8 abdominal segments and spatulate introvert hooks. The ventro-caudal shield has 3 different patterns: stiff with ribs, and sometimes concentric lines, stiff with feebly-defined ribs but no concentric lines, and soft with firmly adhered sediment particles. Sternaspis is restricted to include species with 7 abdominal segments, falcate introvert hooks, and stiff shields, often exhibiting radial ribs, concentric lines or both. Two new genera incorporate the remaining species: Caulleryaspis has falcate introvert hooks, 7 abdominal segments, and soft shields with sediment particles firmly adhered on them. Petersenaspis has spatulate introvert hooks, 8 abdominal segments, and stiff shields with poorly-defined ribs but no concentric line. The geographic range of most species is smaller than previously indicated. Keys to genera and to all species are also included.
