No environment on Earth imposes greater physical and biological constraints on life than the deep oceanic midwaters. Near-freezing temperatures, the absence of sunlight, enormous pressure, and a low food supply make habitation by any living thing almost inconceivable. Yet 160 species of anglerfishes are found there in surprising profusion. Monstrous in appearance, anglerfishes possess a host of unique and spectacular morphological, behavioral, and physiological innovations. In this fully illustrated book, the first to focus on these intriguing fish, Theodore W. Pietsch delivers a comprehensive summary of all that is known about anglerfishes—morphology, diversity, evolution, geographic distribution, bioluminescence, and reproduction.

What is happening in our oceans? By describing their main elements, this book shows how and why the oceans are being transformed, and suggests possible future scenarios to address this complex, yet often-asked, question. The ocean is being dramatically transformed, but the magnitude of this transformation remains unclear since the ocean is largely inaccessible and still unknown: there is more information about the outer universe than about the deepest parts of our oceans. The author, a marine biologist with extensive research experience, offers a holistic view of our oceans. Focusing on fishing, pollution and the effects of climate change, he identifies and describes the changes occurring in all marine ecosystems, and discusses the long-passed state of equilibrium.
