In the Amazon River lives one of the largest freshwater fish on Earth--the arapaima. This huge river hunter can grow up to 10 feet long and weigh 400 pounds. In its watery home, the arapaima is an apex predator. It hunts for fish and birds, but none of its animal neighbors are large enough or powerful enough to catch this giant fish! Filled with information perfectly suited to the abilities and interests of its primarygrade audience, this colorful, fact-filled book gives readers a chance to learn about the lives of apex predators. The book will also help readers develop their powers of observation and challenge them with activities and critical-thinking questions about the arapaima's physical characteristics, its everyday life, and its hunting abilities.

Air Breathing Fishes: Evolution, Diversity, and Adaptation is unique in its coverage of the evolution of air-breathing, incongruously because it focuses exclusively on fish. This important and fascinating book, containing nine chapters that present the life history, ecology, and physiology of many air-breathing fishes, provides an exceptional overview of air-breathing biology.Each chapter provides a historical background, details the present status of knowledge in the field, and defines the questions needing attention in future research. Thoroughly referenced, containing more than 1,000 citations, and well documented with figures and tables, Air-Breathing Fishes is comprehensive in its coverage and will certainly have wide appeal. Researchers in vertebrate biology, paleontology, ichthyology, vertebrate evolution, natural history, comparative physiology, anatomy and many other fields will find something new and intriguing in Air-Breathing Fishes. - Offers a complete overview of an important and immensely interesting area of research - Provides a perspective of air-breathing fish that spans 300 million years of vertebrate evolution - Contains numerous illustrations as well as comprehensive charts - Provides a synoptic treatment of all the known air-breathing species with important data on their morphological and physiological adaptations

The aim of this book is to systematize and discuss population genetic studies of freshwater fish in a region that harbors the greatest diversity of species among all inland water ecosystems. This volume explores the genetic evaluation for a number of orders, families and species of Neotropical fishes, and provides an overview on genetic resources and diversity and their relationships with fish domestication, breeding, and food production.

The Amazon is a giant piece of "amphibian" land which is the result of complex geological and evolutionary processes. The number of living beings in such a land is difficult to estimate. The interactions between these organ isms and the environment are fascinating but barely understood. These features lured us to the Amazon in 1981. However, soon after, we realized that the dimensions of these interactions were overwhelming. This book is designed to review aspects of the physiology and biochemistry of fishes of the Amazon. The description of the pulsative nature of the environment and the distinct features of the ichthyofauna of the Amazon were central to the main goal. Nevertheless, any complete view is limited by the magnitude of the intraspecific variability coupled with the complex fluctuations of the environment. Thus, we have placed an emphasis on respiratory physiology and biochemistry. The reference list was made as complete as possible, particularly regarding special publications not readily available. We hope that this book is useful for comparative physiologists, tropical biologists, and the people interested in interactions between organ isms and their environment. We are grateful to many people who contributed to the making of this book. Our initial ideas were influenced by Drs. Arno Schwantes, Maria Lufza Schwantes, Jose Tundisi, Anna Emflia Vazzoler, and Naercio Menezes.

Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.
