between the organ systems of cephalopods and those of less ambitious molluscs. Octopus does, as we would predict, live close to the limits set by its own physiology. The circulation, to take one example, is barely adequate for such an active animal, mainly because of the absence of any system for pack aging the blood pigment; haemocyanin in solution is a poor oxygen carrier. Cephalopod blood can transport less than 5 millilitres of oxygen per 100 ml of blood (compared with about 15 vol% in fish) and the whole supercharged system of triple hearts, high blood pressure and pulsating blood vessels succeeds only in returning blood that retains less than 30% of its dissolved oxygen by the time it reaches the gills. This at rest; the effect of exercise is immediate and surprisingly long lasting even in octopuses as small as 300 g, which must very swiftly run into oxygen debt when they flee from predators or pursue their prey (Sections 3.2.2, 3.2.4). Digestion, too would seem to be limiting. As with other molluscs, digestion in Octopus is based on secretion absorption cycles by a massive diverticulum of the gut, an adequate system in a less hectic past, but scarcely appropriate in a predator that must be an opportunist in the matter of feeding. Octopus feeds mainly at night, and spends a great deal of every day sitting at home.

Acarology: Proceedings of the 10th International Congress is a timely overview of the current international research mites and ticks. The outcome of a conference of leading acarologists, it presents major reviews of all current areas of research including: *advances in acarine biodiversity and systematics. *human and livestock diseases transmitted by ticks and other parasitic mites. *interactions between mites and their food plants. *mites as biological control agents. *use of genetic markers in mite population studies. *mites as bioindicators. *ecology and biology of soil mites. *mite evolutionary ecology and reproduction. *advances in acarine diversity and systematics. The 90 papers in the book represent some of the best research from leading international researchers from over 50 countries, and helps to establish priorities for future research. All papers have been peer reviewed and edited. Acarology is a comprehensive and important addition to the world literature on mites, and is an essential addition to all acarological and entomological reference collections.

"More than seventy percent of the earth's surface is covered by the ocean which is home to a staggering and sometimes overwhelming diversity of organisms, the majority of which reside in pelagic form. Marine invertebrate larvae are an integral component of this pelagic diversity and have stimulated the curiosity of researchers for centuries. This accessible, upper-level text provides an important and timely update on the topic of larval evolution and ecology, representing the first major synthesis of this interdisciplinary field for more than 20 years. The content is structured around four major areas: evolutionary origins and transitions in developmental mode; functional morphology and ecology of larval forms; larval transport, settlement, and metamorphosis; larval ecology in extreme and changing environments. This novel synthesis integrates traditional larval ecology with life history theory, evolutionary developmental biology, and modern genomics research to provide a research and teaching tool for decades to come." -- from the rear cover.

The fifteen chapters which comprise this study explore the most fundamental biological processes in the largest and least understood habitat on earth- the deep sea.

The Second Edition of the CRC Handbook of Mariculture provides an extensive comparison of marine shrimp culture techniques from around the world. This extensively revised and updated Second Edition focuses on growout systems that have contributed to the production success of shrimp farms and systems worldwide. Topics covered include methods for the culture and preparation of algae, rotifers, Artemia, and other foodstuffs for use in crustacean farms; recent developments on enriching larval food organisms to improve crustacean diets; conditioning and spawning penaeid shrimp; obtaining and manipulating shrimp eggs and sperm for controlled reproduction and use of intensive nursery raceways for juvenile shrimp production; and discussions of many types of marine shrimp growout systems. In addition, culture systems used in Hawaii, Ecuador, Taiwan, and Japan are described in detail. Significant new information from Japan on hormonal control of penaeid shrimp maturation and spawning is discussed. Marine shrimp and Macrobrachium shrimp diseases by the foremost authorities in the area are presented with detailed photographs and illustrations to help identify diseases. The book also includes an update on American lobster larval and juvenile culture.
