Whales are mysterious and fascinating creatures. Despite modern technology, their world is still largely unexplored and unknown. They can only be seen, or rather glimpsed, when they are near the sea surface, either from boats, or perhaps from shore, or underwater by divers. They also reach astonishing sizes – the blue whale, for example, can grow to 30 metres in length, equivalent to the height of a six-storey building, and can weigh more than 130 tonnes. Seven ‘Great Whales’ are found in the coastal waters surrounding Australia. These include six of the largest baleen whales – blue whale, fin whale, humpback whale, sei whale, Bryde’s whale and southern right whale – and the sperm whale, the largest toothed whale. This book provides a detailed account of these extraordinary mammals. As well as the seven Great Whales, a smaller species – the minke whale – is included because of its special interest to Australians. The book describes whales’ highly specialised mammalian structure and biology, and the history of people’s association with them, at first through legend and wonder, then whaling, and more recently whale watching. It also looks at their past and current status, and the conservation initiatives that are in place to protect them from existing or potential threats. With both historical and recent photographs, as well as an extensive glossary, Great Whales will be enjoyed by natural history enthusiasts, zoologists and students alike.

Whales and elephants are iconic giants of the marine and terrestrial animal world. Both are conspicuous representatives of wildlife conservation. The issues of whaling and the ivory trade are closely linked, both legally and politically, in many ways; some obvious, and some surprising. The treatment of both whales and elephants will be politically and legally contentious for years to come, and is of great significance to conservation in general. This book examines the current state of international environmental law and wildlife conservation through a comparative analysis of the treatment of whales and elephants. In particular, it describes the separate histories of international governance of both whales and elephants, presenting the various treaties through which conservation has been implemented. It is shown that international environmental law is influenced and shaped by important political actors – many with opposing views on how best conservation, and sustainable development, principles are to be implemented. Modern environmental treaties are changing as weaknesses and loopholes are exposed in older, and possibly outdated, treaties such as the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the International Convention for the Regulation of Whaling (ICRW). Such weaknesses can be seen in the efforts made by some states to circumvent or weaken CITES and the International Whaling Commission and to resume commercial whaling, and further in the efforts of countries to resume trade in ivory. The argument is made that the Convention on Biological Diversity could be used to begin reconciling opposed views and to focus conservation efforts. The argument is made that effective conservation of species cannot be achieved through individual treaties, but only through a synergistic approach involving multilateral environmental agreements – 'ecosystems of legal instruments'.

Within little more than a generation, whale-watching has been subject to global industrial development. It has been portrayed by destinations and business operators, and advocated by environmental groups, as a sustainable activity and an alternative to whaling. However, in recent years the sustainability of these activities has increasingly been questioned, as research shows that repeated disturbance by boat traffic can severely disrupt critical behaviours of cetaceans in the wild. Bringing together contributions by international experts, this volume addresses complex issues associated with commercial whale-watching, sustainable development and conservation of the global marine environment. It highlights widely expressed concerns for the failure of policy, planning and management and pinpoints both long-standing and emerging barriers to sustainable practice. Featuring numerous case studies, the book provides critical insights into the diverse socio-cultural, political, economic and ecological contexts of this global industry, highlighting the challenges and opportunities that arise along the pathways to sustainability.

"Eye of the Whale focuses on one great whale in particularthe coastal-traveling California gray whale. Gray whales make the longest migration of any mammal - from the lagoons of Baja California to the feeding grounds of the Bering Strait between Alaska and Siberia (nearly 6,000 miles). That the gray whale exists today is nothing short of miraculous. Whaling fleets twice massacred the species to near extinction - first during the nineteenth century and again during the early part of the twentieth century."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

The Gray Whale: Eschrichtius robustus provides an introduction to the understanding of Eschrichtius robustus or the gray whale. This book explores the life processes, reproduction, and growth of large cetacean populations. Organized into four parts encompassing 25 chapters, this book begins with an overview of the gray whale evolution, fossils, and subfossil remains, range, and systematics in historical times. This text then presents the historical of gray whale exploitation and the economic importance of these whales to humans. Other chapters consider the gray whale migration, abundance, and seasonal distribution in the wake of the California population's recovery from depletion. This book discusses as well the methods used in shore-based censuses during migration and in aerial surveys of gray whales taken on their winter grounds. The final chapter deals with some innovative approaches to the study of free-ranging cetaceans. This book is a valuable resource for anthropologists, paleontologists, biologists, and naturalists.
