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
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.
Arapaimas are fearsome predators. They lurk in the waters of the Amazon, ready to devour any prey they see with their large, powerful mouths! In this book, reluctant readers will learn all about arapaimas and their life in the Amazon through leveled text and vibrant photographs. Special features such as a size comparison chart, identification chart, and record catch will reel readers in and leave them wanting to learn more!
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.
An exploration into the untold lives of 50 of the most compelling fish living in our oceans and waterways.
Join Zeb Hogan, host of the National Geographic television show Monster Fish, on the science adventure of a lifetime. On May 1, 2005, a Thai fisherman caught a truly monstrous Mekong giant catfish. At 646 pounds, it captured the world’s attention, and with awe and wonder, it was deemed the largest freshwater fish on record. There was no denying its size, but when biologist and research associate professor Hogan saw a photo of the fish, he wondered if it really was the biggest in the world. To his surprise, no one had systematically sought to answer the question: Which of the giant freshwater species really was the largest? Seeking to answer that question has brought Hogan face to face with massive arapaima and piranha in the Amazon, alligator gar in Texas, pigeon-eating wels catfish in France, stingrays in Cambodia, and the gnarled-toothed sawfish in Australia. Part of his scientific adventure has been captured on Monster Fish, and Hogan now tells the full story of his 25-year quest to understand the mysteries of some of the oldest, largest, most bizarre creatures on Earth. The fate of these giant fish motivates Hogan to understand the various species he studies. The megafish’s numbers are dwindling, and the majority of them face extinction. In this book, he teams up with award-winning journalist Stefan Lovgren to tell, for the first time, the remarkable and troubling story of the world’s largest freshwater fish. It is a story that stretches across the globe, chronicling a race against the clock to find and protect these ancient leviathans before they disappear forever. Chasing Giants: In Search of the World’s Largest Freshwater Fish combines science, adventure, and wonder to provide insights into the key role the massive fish of our lakes and rivers play in our past, present, and future.
