"The third edition of Ecology and Classification of North American Freshwater Invertebrates continues the tradition of in-depth coverage of the biology, ecology, phylogeny, and identification of freshwater invertebrates from the USA and Canada. This text serves as an authoritative single source for a broad coverage of the anatomy, physiology, ecology, and phylogeny of all major groups of invertebrates in inland waters of North America, north of Mexico." --Book Jacket.

"For each of the thirty-two currently recognized phyla, Invertebrates presents detailed classifications, revised taxonomic synopses, updated information on general biology and anatomy, and current phylogenetic hypotheses, organized with boxes and tables, and illustrated with abundant line drawings and new color photos. The chapters are organized around the "new animal phylogeny," while introductory chapters provide basic background information on the general biology of invertebrates. Two new coauthors have been added to the writing team, and twenty-two additional invertebrate zoologists have contributed to chapter revisions. This benchmark volume on our modern views of invertebrate biology should be in every zoologist's library"--

Popular interest in the observation and study of freshwater invertebrates is increasing. This book meets the needs of this growing audience of naturalists, environmentalists, anglers, teachers, students, and others by providing substantive information in easy-to-understand, non-technical language for many groups of invertebrates commonly found in the streams, lakes, ponds, and other freshwater environments of North America. Section One provides background information on the biology and ecology of freshwater organisms and environments and explains why and how invertebrates can be studied, simply and without complex equipment, in the field and the laboratory. Section Two describes nearly 100 of the most common groups of invertebrates, and for each group a whole-body colour illustration is provided along with brief text pointing out the most important features that identify members of the group. Section Three contains in-depth descriptions of the life history, behaviour, and ecology of the various invertebrate groups, and explains their important ecological contributions and relationships to humans. The Guide is broad in scope, geographically and taxonomically, and it is written at a substantive yet easily accessible level that will appeal to both novices and those with more advanced knowledge of the subject. It also contains more than 100 specially commissioned colour illustrations by the well-known scientific illustrator Amy Bartlett Wright that will greatly facilitate the easy and rapid identification of specimens.

So much has to be crammed into today's biology courses that basic information on animal groups and their evolutionary origins is often left out. This is particularly true for the invertebrates. The second edition of Janet Moore's An Introduction to the Invertebrates fills this gap by providing a short updated guide to the invertebrate phyla, looking at their diverse forms, functions and evolutionary relationships. This book first introduces evolution and modern methods of tracing it, then considers the distinctive body plan of each invertebrate phylum showing what has evolved, how the animals live, and how they develop. Boxes introduce physiological mechanisms and development. The final chapter explains uses of molecular evidence and presents an up-to-date view of evolutionary history, giving a more certain definition of the relationships between invertebrates. This user-friendly and well-illustrated introduction will be invaluable for all those studying invertebrates.

This textbook is the most concise and readable invertebrates book in terms of detail and pedagogy (other texts do not offer boxed readings, a second color, end of chapter questions, or pronunciation guides). All phyla of invertebrates are covered (comprehensive) with an emphasis on unifying characteristics of each group.

The plates in this book capture incredibly detailed impressions and casts of ancient life, contrasting them with forms, such as the horseshoe crab and the chambered nautilus, that persist today virtually unchanged. Paul D. Taylor and David N. Lewis, both of the Natural History Museum, London, have written a comprehensive and accessible resource.

This overview and introduction to the study of fossil invertebrates emphasizes both soft and skeletal anatomy, as well as the relationship between those known only from fossils and animals living today. It lays the foundation for studentsÕ eventual abilities to (1) recognize many of the most abundant fossils, (2) appreciate their value in interpreting ancient environments of deposition, and (3) use them as tools for stratigraphic correlation.

Invertebrate Medicine, Second Edition offers a thorough update to the most comprehensive book on invertebrate husbandry and veterinary care. Including pertinent biological data for invertebrate species, the book’s emphasis is on providing state-of-the-art information on medicine and the clinical condition. Invertebrate Medicine, Second Edition is an invaluable guide to the medical care of both captive and wild invertebrate animals. Coverage includes sponges, jellyfish, anemones, corals, mollusks, starfish, sea urchins, crabs, crayfish, lobsters, shrimp, hermit crabs, spiders, scorpions, and many more, with chapters organized by taxonomy. New chapters provide information on reef systems, honeybees, butterfly houses, conservation, welfare, and sources of invertebrates and supplies. Invertebrate Medicine, Second Edition is an essential resource for veterinarians in zoo animal, exotic animal and laboratory animal medicine; public and private aquarists; and aquaculturists.

This is the largest species of sea pen encountered by divers in the northern Pacific. the short, slender branches of the stalk are white, as are the polyps.
