This is the third volume of the entirely rewritten, revised and updated version of the original FAO Catalogue of Cephalopods of the World (1984). The present Volume is a multiauthored compilation that reviews 13 families, i.e. (in alphabetical order), Alloposidae, Amphitretidae, Argonautidae, Bolitaenidae, Cirroctopodidae, Cirroteuthidae, Octopodidae, Ocythoidae, Opisthoteuthidae, Stauroteuthidae, Tremoctopodidae, Vampyroteuthidae, Vitreledonellidae, with 56 genera and the 280 species known and named to the date of the completion of the volume.

A current and comprehensive species list of marine invertebrates of Alaska is essential for effective management of living marine resources, sustainable fisheries, conservation of vulnerable ecosystems, and advancement of our knowledge of biodiversity and ecosystem function. Furthermore, the most current checklist available to resource managers and scientists is quite dated and limited in that it only includes the marine invertebrates of the southern coast of Alaska to California. Since that checklist was published, many new species have been described, many range extensions have been discovered, and considerable changes in higher-level systematics have been made. The checklist that we have compiled lists 3708 species and presents for each species the currently accepted scientific name and its significant synonyms, common names, type localities, geographic and depth distributions, a general statement of abundance in Alaska when known (e.g., rare, uncommon, common, abundant), and general remarks. It includes species recorded in the marine waters of Alaska from the intertidal zone, continental shelf, and upper continental slope to abyssal depths, from the Beaufort Sea at the Arctic border with Yukon, Canada; the eastern Chukchi Sea, the eastern Bering Sea, the Aleutian Islands to the western border with Russia; and the Gulf of Alaska to Dixon Entrance at the southern border with British Columbia. Sound and reliable taxonomic identifications are necessary to monitor and predict changes in the distribution and abundance of marine species. The current status and future direction of the study of Alaskan marine invertebrate biodiversity are briefly discussed.

This volume explores the diversity of distributed eyes and other unusual visual systems in nature. It compares the unique themes of optics, neural processing, and behavioral control that emerge from these visual systems with more-canonical eyes. This volume attempts to answer a number of questions about distributed visual systems. What are distributed visual systems good for, how do they function, and why have they arisen independently in so many phyla? Why are eye designs and visual system arrangements much more diverse in invertebrates? Each chapter includes an overview of the visual systems that exist in their group of animals, relates vision to ecology, and takes a comparative approach.

Increasing interest in marine biology and its relevance to environmental issues creates a demand for authoritative reviews of recent research. Oceanography and Marine Biology has addressed this demand for nearly 40 years. This annual review considers basics of marine research, special topics, and emerging new areas. Regarding the marine sciences as a unified field, the text features contributors who are actively engaged in biological, chemical, geological, and physical aspects of marine science. This edition includes a full color insert and covers such topics as the ecological status of the Great Barrier Reef, the effects of coral bleaching on fisheries, and the biology of octopus larvae.

Mollusks have been important to humans since our earliest days. Initially, when humans were primarily interested in what they could eat or use, mollusks were important as food, ornaments, and materials for tools. Over the centuries, as human knowledge branched out and individuals started to study the world around them, mollusks were important subjects for learning how things worked. In this volume, the editors and contributors have brought together a broad range of topics within the field of malacology. It is our expectation that these topics will be of interest and use to amateur and professional malacologists.
