Which species of sharks live within 500 nautical miles of North American shores, and what do we know about them? Jose I. Castro's The Sharks of North America is the first comprehensive book in sixty years to address these questions, and it does so with unrivaled authority and aesthetic detail.
The 135 comprehensive species accounts summarize the present knowledge. Each begins with the etymology of a species' common and scientific names, followed by the description, identifying characteristics, geographic range, biology, reproduction, location of nurseries, growth and longevity, and relation to humans. These accounts synthesize decades of research and first-hand examination of sharks collected in fisheries and research operations across the continent. They are thorough, current, and dispel many myths and misunderstandings found in the scientific and popular literature.
Each species is illustrated by one or more original profile figures in color, augmented by images of the snout, upper and lower teeth, and dermal denticles. The stunning color illustrations have been painted directly from freshly dead sharks or Castro's photographs of live or fresh specimens. Their anatomical accuracy and true-to-life coloration are unmatched. The detailed pen and ink drawings of the snout and teeth are crucial aids to species identification, as are the exquisite scanning electron microphotographs of dermal denticles.
The Sharks of North America will serve as the standard reference on sharks for the twenty-first century and is certain to become the primary source of information for anyone interested in sharks, from professional biologists and conservationists to students, informed laypersons, and fishermen."

The sea has been an endless source of fascination, at once both alluring and mysterious, a place of wonder and terror. The Sea Journal contains first-hand records by a great range of travellers of their encounters with strange creatures and new lands, full of dangers and delights, pleasures and perils. In this remarkable gathering of private journals, log books, letters and diaries, we follow the voyages of intrepid sailors, from the frozen polar wastes to South Seas paradise islands, as they set down their immediate impressions of all they saw. They capture their experiences while at sea, giving us a precious view of the oceans and the creatures that live in them as they were when they were scarcely known and right up to the present day. In a series of biographical portraits, we meet officers and ordinary sailors, cooks and whalers, surgeons and artists, explorers and adventurers. A handful of contemporary mariners provide their thoughts on how art remains integral to their voyaging lives. Often still bearing the traces of their nautical past, the intriguing and enchanting sketches and drawings in this book brilliantly capture the spirit of the oceans and the magic of the sea.

A vivid, up-to-date tour of the Earth's last frontier, a remote and mysterious realm that nonetheless lies close to the heart of even the most land-locked reader. The sea covers seven-tenths of the Earth, but we have mapped only a small percentage of it. The sea contains millions of species of animals and plants, but we have identified only a few thousand of them. The sea controls our planet's climate, but we do not really understand how. The sea is still the frontier, and yet it seems so familiar that we sometimes forget how little we know about it. Just as we are poised on the verge of exploiting the sea on an unprecedented scale-mining it, fertilizing it, fishing it out-this book reminds us of how much we have yet to learn. More than that, it chronicles the knowledge explosion that has transformed our view of the sea in just the past few decades, and made it a far more interesting and accessible place. From the Big Bang to that far-off future time, two billion years from now, when our planet will be a waterless rock; from the lush crowds of life at seafloor hot springs to the invisible, jewel-like plants that float at the sea surface; from the restless shifting of the tectonic plates to the majestic sweep of the ocean currents, Kunzig's clear and lyrical prose transports us to the ends of the Earth.

This is an inspiring tour of the world's oceans and 80 of its most notable inhabitants. Beautifully illustrated, the book includes fascinating stories of the fish, shellfish and other sea life that have somehow impacted human life - whether in our medicine, culture or folklore - in often surprising and unexpected ways.

This title is suitable for children of ages 8 years & over. In this engaging story of one of nature's most fascinating creatures, science educator Stephen Whitt follows a mother sea turtle on the most difficult and dangerous journey of her life, the journey home to lay her eggs. Along the way he shows young readers how the events of the universe, many of them both far away and long ago, have resulted in a world where a turtle may swim through a salty sea, struggle up a sandy beach, and dig her nest just beyond the reach of the highest tide. "The Turtle and the Universe" is a story of connection. Through the life and struggles of one female turtle, youngsters learn that the universe is a single thing. Everything within the universe is linked to everything else, by time, by origin, by ultimate fate. In the elements that make the sea turtle there are shadows of an exploded star from far away and long ago. In the movement of the turtle's flippers is the energy of the fireball that began our universe some thirteen billion years ago. In the sand, in the seawater, in the eggs the turtle lays there are hints of the deep connections shared by all the things, and all the events, that we call the universe. Whitt also reveals how the actions of our own species are altering the world that we and the sea turtles share. He underscores the necessity of using our natural resources wisely to ensure the future of the whole interconnected earth. This elegantly told story captures the many wonders that science discovers in the natural world while teaching children essential facts of astronomy, chemistry, and biology.

Part travelogue, part history, and part environmental treatise, "Mekong - The Occluding River" is above all else an urgent warning that factors such as pollution, ecological devastation, and the depletion of natural resources are threatening the very existence of the Mekong River. Author Ngo The Vinh combines his vivid travel notes and collection of photographs with a meticulously researched history of the environmental degradation of the Mekong River. Translated from Vietnamese, the best-selling treatise outlines the myriad threats facing the river today. From oil shipments feeding the industrial cities of southwestern China to gigantic hydroelectric dams known as the Mekong Cascades in Yunnan province, China is the worst environmental offender, though the other nations along Mekong's banks behave no better. From Thailand to Laos to Vietnam, hydroelectric dams that threaten the Mekong and its inhabitants are being built at an alarming rate. To save the Mekong, Ngo The Vinh calls upon all the nations that benefit from its life-giving water to observe the "Spirit of the Mekong" in the implementation of all future development projects. To achieve this end, there must be a concerted and sustained commitment to cooperation and sustainability. At this critical cross-roads, we should remind ourselves of the mantra from Sea World San Diego: "Extinction is forever. Endangered means we still have time."

The deep sea is the last, vast wilderness on the planet. For centuries, myth-makers and storytellers have concocted imaginary monsters of the deep, and now scientists are looking there to find bizarre, unknown species, chemicals to make new medicines, and to gain a greater understanding of how this world of ours works. With an average depth of 12,000 feet and chasms that plunge much deeper, it forms a frontier for new discoveries. The Brilliant Abyss tells the story of our relationship with the deep sea - how we imagine, explore and exploit it. It captures the golden age of discovery we are currently in and looks back at the history of how we got here, while also looking forward to the unfolding new environmental disasters that are taking place miles beneath the waves, far beyond the public gaze. Throughout history, there have been two distinct groups of deep-sea explorers. Both have sought knowledge but with different and often conflicting ambitions in mind. Some people want to quench their curiosity; many more have been lured by the possibilities of commerce and profit. The tension between these two opposing sides is the theme that runs throughout the book, while readers are taken on a chronological journey through humanity's developing relationship with the deep sea. The Brilliant Abyss ends by looking forwards to humanity's advancing impacts on the deep, including mining and pollution and what we can do about them.

About seventy-one per cent of the Earth's surface is water, and even on dry land we remain closely connected to aquatic life. It provides us with oxygen, food, medicine and materials. Wild waterlife infiltrates our lives in many surprising ways. Every other breath we take is filled with oxygen provided by ocean-dwelling microscopic plants. A type of seaweed provides a means to directly test whether people are infected with viruses, including Covid-19. Robotics design takes inspiration from a pike's ability to accelerate with greater g-force than a Porsche. Wild Waters by Susanne Masters is a celebration of the breadth of wildlife that can be found in and around our varied waterways, from oceans and rivers to rock pools and ponds. Armchair explorers can read a fascinating account of how aquatic plants and animals enrich human life. Swimmers, paddleboarders, dog walkers, families and anyone with a passion for the great outdoors can learn about local wildlife, including when and where to look for different species without causing any harm. With stunning illustrations by Alice Goodridge, Wild Waters provides a tantalising insight into the world beneath the surface.

The assemblage of animals living in sandy shores is richer than it might first appear, and it offers wonderful opportunities for ecological explanation without the need for expensive equipment. This book introduces the natural history of the community and provides keys that will enable readers to name the animals they find. It provides practical approaches for behavioural and ecological studies, including the survey and monitoring of populations. Local investigations of this kind form an essential basis for planning the conservation of sandy shore habitats, which are important both in their own right and as feeding grounds for birds. This is a digital reprint edition of the book originally published in 1994 with ISBNs 0855462949 (hbk) & 0855462930 (pbk).

From the acclaimed author of Fragrance of Grass comes a meditation on water and nature, fishing and growing older. On the Water is a gorgeously written collection of essays that all take place on or near the water and pay tribute to the flora and fauna associated with those ecosystems. There are essays about the finer points of tickling rainbow trout in the streams of Normandy, and of eagles and ospreys fishing for bass while barely breaking the surface of the water. There are stories of droughts and floods, of dogs and boats, of worms and rattlesnakes and even of catching and cooking soft-shell turtles that taste like osso-bucco. There is fishing and diving in the Bahamas, tarpon fishing in the Florida Keys, and fly fishing for sailfish in Central America. And there are larger-than-life personalities that are bigger than the fish tales they tell! On the Water is a finely honed and well crafted collection of tales for the true sportsman and makes for a perfect companion volume to la Valdene's celebrated collection of essays on hunting.

Delphus E. Carpenter (1877-1951) was Colorado's commissioner of interstate streams during a time when water rights were a legal battleground for western states. A complex, unassuming man as rare and cunning in politics and law as the elusive silver fox of the Rocky Mountain West, Carpenter boldly relied on negotiation instead of endless litigation to forge agreements among states first, before federal intervention. In Silver Fox of the Rockies, Daniel Tyler tells Carpenter's story and that of the great interstate water compacts he helped create. Those compacts, produced in the early twentieth century, have guided not only agricultural use but urban growth and development throughout much of the American West to this day. In Carpenter's time, most western states relied on the doctrine of prior appropriation--first in time, first in right--which granted exclusive use of resources to those who claimed them first, regardless of common needs. Carpenter feared that population growth and rapid agricultural development in states sharing the same river basins would rob Colorado of its right to a fair share of water. To avoid that eventuality, Carpenter invoked the compact clause of the U.S. Constitution, a clause previously used to settle boundary disputes, and applied it to interstate water rights. The result was a mechanism by which complex issues involving interstate water rights could be settled through negotiation without litigating them before the U.S. Supreme Court. Carpenter believed in the preservation of states' rights in order to preserve the constitutionally mandated balance between state and federal authority. Today, water remains critically important to the American West, and thegreat interstate water compacts Carpenter helped engineer constitute his most enduring legacy. Of particular significance is the Colorado River Compact of 1922, without which Hoover Dam could never have been built.
