The definitive resource on tunas and billfishes from the world's top authorities. Tunas and billfishes are peak predators of the oceans. Admired by scientists and naturalists for their speed, grace, unique physiology, and diversity, they are important both ecologically and socioeconomically. Vital sources of food and income for many maritime nations, whose fleets of vessels target them with huge purse seines or miles-long lines, these exhilarating fishes are also highly desired and avidly sought by big game fishers across the globe. In Tunas and Billfishes of the World, Bruce Collette, a leading marine ichthyologist and conservationist, and John Graves, an expert on the biology, fisheries, and management of tunas and billfishes, focus on three families of fishes: Scombridae, the mackerels and tunas; Istiophoridae, sailfish and marlins; and Xiphiidae, the Swordfish. Over the course of 61 in-depth species accounts, Collette and Graves * describe what each species looks like and where it lives * include detailed summaries of the fishes' biology-size, food, habitat, reproduction, and early life history * offer current information about fisheries interests and conservation status * provide up-to-date evaluations of the threat status for each species Accompanied by full-color, scientifically accurate illustrations by renowned illustrator Val Kells, along with range maps for each species, this spectacular volume is the essential book on these majestic inhabitants of the sea. Destined to quickly become the standard reference for scientists, students, and naturalists, Tunas and Billfishes of the World will also be prized by all fishers who pursue these species.

Wyl Menmuir's The Draw of the Sea is a beautifully written and deeply moving portrait of the Cornish Coast and the people who make their livings there, examining the ephemeral but universal pull the sea holds over the human imagination. 'A beautiful portrait of lives shaped by the swell of ocean and tide - a powerful salt-thread of connection' - Raynor Winn, author of The Salt Path Since the earliest stages of human development, the sea has fascinated and entranced us. It feeds us, sustaining communities and providing livelihoods, but it also holds immense destructive power which can take all those away in an instant. It connects us to far away places, offering the promise of new lands and voyages of discovery, but also shapes our borders, carving divisions between landmasses and eroding the very ground beneath our feet. In this beautifully-written meditation on what it is that draws us to the waters' edge, author Wyl Menmuir tells the stories of the people whose lives revolve around the sea in the Cornish community where he lives. In twelve interlinked chapters, Menmuir explores the lives of local fishermen steeped in the rich traditions of a fishing community, the beachcombers who wander the shores in search of the varied objects which wash ashore and the stories they tell, and all number of others who have made their lives on the beautiful Cornwall coast. In the specifics of these livelihoods and their rich histories and traditions, Wyl Menmuir captures the universal human connection to the sea. Into this seductive tapestry, Wyl weaves the story of how the sea has beckoned, consoled and restored him. This book is a meaningful and moving work into how we interact with the environment around us, and how it comes to shape the course of our lives. As unmissable as it is compelling, as profound as it is personal, this must-read book will delight anyone familiar with the intimate and powerful pull which the sea holds over us.

Trundling along in essentially the same form for some 220 million years, turtles have seen dinosaurs come and go, mammals emerge, and humankind expand its dominion. Is it any wonder the persistent reptile bested the hare? In this engaging book physiologist Donald Jackson shares a lifetime of observation of this curious creature, allowing us a look under the shell of an animal at once so familiar and so strange. Here we discover how the turtle's proverbial slowness helps it survive a long, cold winter under ice. How the shell not only serves as a protective home but also influences such essential functions as buoyancy control, breathing, and surviving remarkably long periods without oxygen, and how many other physiological features help define this unique animal. Jackson offers insight into what exactly it's like to live inside a shell-to carry the heavy carapace on land and in water, to breathe without an expandable ribcage, to have sex with all that body armor intervening. Along the way we also learn something about the process of scientific discovery-how the answer to one question leads to new questions, how a chance observation can change the direction of study, and above all how new research always builds on the previous work of others. A clear and informative exposition of physiological concepts using the turtle as a model organism, the book is as interesting for what it tells us about scientific investigation as it is for its deep and detailed understanding of how the enduring turtle "works."

This reference detailing 1,600 animals with 2,000 photographs and descriptive text is not only the most comprehensive visual field guide to marine invertebrate life inhabiting the waters from Thailand to Tahiti, but also a pictorial tour de force skilfully bridging science and the aesthetic. For the past five years the two authors/photographers have delved deep into uncharted waters, not only visually documenting numerous species for the first time, but also incorporating the most recent taxonomic research of more than 40 scientific specialists. The text focuses on mobile species, highlighting crustaceans, molluscs, worms and echinoderms, however the pages include an overview of attached marine animals, and also explore facets of marine invertebrate behaviour. The guide provides a boon of information for diving photographers and underwater naturalists, known as critter hunters, who enjoy one of the most challenging games in the sea - searching for charismatic mini-fauna of the reef. And for the armchair adventurers, the brilliant gallery of images brings an unseen, unimagined world to the surface like never before.

The Colorado River Basin's importance cannot be overstated. Its living river system supplies water to roughly forty million people, contains Grand Canyon National Park, Bears Ears National Monument, and wide swaths of other public lands, and encompasses ancestral homelands of twenty-nine Native American tribes. John Wesley Powell, a one-armed Civil War veteran, explorer, scientist, and adept federal administrator, articulated a vision for Euro-American colonization of the "Arid Region" that has indelibly shaped the basin-a pattern that looms large not only in western history, but also in contemporary environmental and social policy. One hundred and fifty years after Powell's epic 1869 Colorado River Exploring Expedition, this volume revisits Powell's vision, examining its historical character and its relative influence on the Colorado River Basin's cultural and physical landscape in modern times. In three parts, the volume unpacks Powell's ideas on water, public lands, and Native Americans-ideas at once innovative, complex, and contradictory. With an eye toward climate change and a host of related challenges facing the basin, the volume turns to the future, reflecting on how-if at all-Powell's legacy might inform our collective vision as we navigate a new "Great Unknown."

An Underwater Guide to the Red Sea introduces over 1,000 species of invertebrate and over 200 species of coral, forming the basis of a marine eco-system which includes 1,100 species of fish, of which just under 20% are endemic. The high level of endemism is one of the main factors that makes scuba diving in Egypt so attractive. The dive sites offer unobstructed opportunities to spot tropical marine life in crystal-clear waters, ranging from sharks and dolphins to gorgonian fans and feather-stars. Diving types include shallow patch reefs, drift dives and walls, and a collection of some of the most interesting wrecks you are likely to find anywhere, including the world-famous Carnatic and Thistlegorm wrecks. Many of the reefs stretch out far into the sea and form intricate labyrinths of plateaus, lagoons, caves and gardens. Divided into three parts, the first is an introduction to diving and snorkelling in the Red Sea including what to expect and where to base yourself; next a guide to the best sites for diving and snorkelling; and finally a photographic identification of 282 of the most common species of fish, invertebrates, corals and megafauna. The second edition has been carefully updated, so that it continues to be an essential pocket guide for divers and snorkellers.

From beer labels to literary classics like A River Runs Through It, trout fishing is a beloved feature of the iconography of the American West. But as Jen Brown demonstrates in Trout Culture: How Fly Fishing Forever Changed the Rocky Mountain West, the popular conception of Rocky Mountain trout fishing as a quintessential experience of communion with nature belies the sport's long history of environmental manipulation, engineering, and, ultimately, transformation. A fly-fishing enthusiast herself, Brown places the rise of recreational trout fishing in a local and global context. Globally, she shows how the European sport of fly-fishing came to be a defining, tourist-attracting feature of the expanding 19th-century American West. Locally, she traces the way that the burgeoning fly-fishing tourist industry shaped the environmental, economic, and social development of the Western United States: introducing and stocking favored fish species, eradicating the less favored native "trash fish," changing the courses of waterways, and leading to conflicts with Native Americans' fishing and territorial rights. Through this analysis, Brown demonstrates that the majestic trout streams often considered a timeless feature of the American West are in fact the product of countless human interventions adding up to a profound manipulation of the Rocky Mountain environment. https://www.youtube.com/watch?v=ZKMwEkKj9jg

Since "Jaws" scared a nation of moviegoers out of the water three decades ago, great white sharks have attained a mythical status as the most frightening and mysterious monsters to still live among us. Each fall, just twenty-seven miles off the San Francisco coast, in the waters surrounding a desolate rocky island chain, the world's largest congregation of these fearsome predators gathers to feed. Journalist Susan Casey first saw the great whites of the Farallones in a television documentary. Within months, she was sitting with the program's two scientists in a small motorboat as the sharks - some as long as twenty feet, as wide as a semitrailer - circled around them. From this first encounter, Casey became obsessed with these awe-inspiring creatures, and a plan was hatched for her to join the scientists and follow their research. "The Devil's Teeth" is the riveting account of that one fateful shark season. An exhilarating adventure story, "The Devil's Teeth" offers a glimpse into a violent, uncivilized world ruled by nature's most powerful and mysterious predators, a world where man is neither wanted nor needed.
