From two scientists who have been at the forefront of manatee research for over three decades, The Florida Manatee offers an engaging, accessible introduction to manatee biology, including communication, diet, long-distance migration, and much more. This second edition is updated with new scientific research, as well as discussions of recent conservation efforts-largely driven by manatee injuries and deaths resulting from boat collisions-that have contributed to the robust growth of manatee numbers in Florida. It also includes the latest predictions for manatee populations and health in the future, both in Florida and worldwide. This is the perfect book for anyone seeking the most comprehensive, current information on this fascinating marine mammal.
How intelligent are dolphins? Is their communication system really as complex as human language? And are they as friendly and peaceful as they are made out to be? The Western world has had an enduring love affair with dolphins since the early 1960s, with fanciful claims of their 'healing powers' and 'super intelligence'. Myths and pseudoscience abound on the subject. Justin Gregg weighs up the claims made about dolphin intelligence and separates scientific fact from fiction. He puts our knowledge about dolphin behaviour and intelligence into perspective, with comparisons to scientific studies of other animals, especially the crow family and great apes. He gives fascinating accounts of the challenges of testing what an animal with flippers and no facial expressions might be animal behaviour, Gregg challenges many of the widespread beliefs about dolphins, while also inspiring the reader with the remarkable abilities common to many of the less glamorized animals around us - such as chickens.

Famed in story as "the great leviathans," sperm whales are truly
creatures of extremes. Giants among all whales, they also have the
largest brains of any creature on Earth. Males can reach a length
of sixty-two feet and can weigh upwards of fifty tons.
This new edition - now with Nancy Jackson as a co-author - continues the themes of the first edition: the need to restore the biodiversity, ecosystem health, and ecosystem services provided by coastal landforms and habitats, especially in the light of climate change. The second edition reports on progress made on practices identified in the first edition, presents additional case studies, and addresses new and emerging issues. It analyzes the tradeoffs involved in restoring beaches and dunes - especially on developed coasts - the most effective approaches to use, and how stakeholders can play an active role. The concept of restoration is broad, and includes physical, ecological, economic, social, and ethical principles and ideals. The book will be valuable for coastal scientists, engineers, planners, and managers, as well as shorefront residents. It will also serve as a useful supplementary reference textbook in courses dealing with issues of coastal management and ecology.
Pinnipeds are marine mammals that include eared seals, true seals, and walruses. This book presents detailed reviews on the ecology and conservation of 10 pinniped species along the coasts and islands in Latin America, from Mexico to Chile and Argentina. Topics covered include their population dynamics, trophic ecology, reproduction, and behavior. In addition, the book addresses major conservation issues regarding climate change, interaction with fisheries, ecotourism, and other human activities.
More than any other locale, the Pacific Ocean has been the meeting place between humans and whales. From Indigenous Pacific peoples who built lives and cosmologies around whales, to Euro-American whalers who descended upon the Pacific during the nineteenth century, and to the new forms of human-cetacean partnerships that have emerged from the late twentieth century, the relationship between these two species has been central to the ocean’s history. Across Species and Cultures: Whales, Humans, and Pacific Worlds offers for the first time a critical, wide-ranging geographical and temporal look at the varieties of whale histories in the Pacific. The essay contributors, hailing from around the Pacific, present a wealth of fascinating stories while breaking new methodological ground in environmental history, women’s history, animal studies, and Indigenous ontologies. In the process they reveal previously hidden aspects of the story of Pacific whaling, including the contributions of Indigenous people to capitalist whaling, the industry’s exceptionally far-reaching spread, and its overlooked second life as a global, industrial slaughter in the twentieth century. While pointing to striking continuities in whaling histories around the Pacific, Across Species and Cultures also reveals deep tensions: between environmentalists and Indigenous peoples, between ideas and realities, and between the North and South Pacific. The book delves in unprecedented ways into the lives and histories of whales themselves. Despite the worst ravages of commercial and industrial whaling, whales survived two centuries of mass killing in the Pacific. Their perseverance continues to nourish many human communities around and in the Pacific Ocean where they are hunted as commodities, regarded as signs of wealth and power, act as providers and protectors, but are also ancestors, providing a bridge between human and nonhuman worlds.
This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.
Hans Thewissen, a leading researcher in the field of whale paleontology and anatomy, gives a sweeping first-person account of the discoveries that brought to light the early fossil record of whales. As evidenced in the record, whales evolved from herbivorous forest-dwelling ancestors that resembled tiny deer to carnivorous monsters stalking lakes and rivers and to serpentlike denizens of the coast. Thewissen reports on his discoveries in the wilds of India and Pakistan, weaving a narrative that reveals the day-to-day adventures of fossil collection, enriching it with local flavors from South Asian culture and society. The reader senses the excitement of the digs as well as the rigors faced by scientific researchers, for whom each new insight gives rise to even more questions, and for whom at times the logistics of just staying alive may trump all science. In his search for an understanding of how modern whales live their lives, Thewissen also journeys to Japan and Alaska to study whales and wild dolphins. He finds answers to his questions about fossils by studying the anatomy of otters and porpoises and examining whale embryos under the microscope. In the book's final chapter, Thewissen argues for approaching whale evolution with the most powerful tools we have and for combining all the fields of science in pursuit of knowledge.
Looking to the vast human history of water worship, a crucial study of our broken relationship with all things aquatic - and how we might mend it. Early human relationships with water were expressed through beliefs in serpentine aquatic deities: rainbow-coloured, feathered or horned serpents, giant anacondas and dragons. Representing the powers of water, these beings were bringers of life and sustenance, world creators, ancestors, guardian spirits and law makers. Worshipped and appeased, they embodied people's respect for water and its vital role in sustaining all living things. Yet today, though we still recognise that 'water is life', fresh- and saltwater ecosystems have been critically compromised by human activities. This major study of water beings, and what has happened to them in different cultural and historical contexts, demonstrates how and why some - but not all - societies have moved from worshipping water to wreaking havoc upon it, and asks what we can do to turn the tide. 'A far-ranging and gorgeously illustrated study, Water Beings explores humanity's enduring but always transforming connections to the wellsprings of life. A profound and entertaining book for a time when reimagining humanity's future has never been more vital.' - Caspar Henderson, author of The Book of Barely Imagined Beings 'With passion, rigor and creative depth, Strang eloquently takes readers across the world to further our understanding of water's natural, cultural, and symbolic qualities. Water beings are brought to life alongside relational beliefs and practices. This is a magnificent work that reflects a rich human/water/culture relationship, and explores possibilities to avoid a climate crisis future.' - Sandy Toussaint, University of Western Australia 'A spellbinding anthropological itinerary through the winding ways of serpentine water beings as they have manifested through history and across cultures. Luminously illustrated, ingeniously researched, and beautifully narrated, Strang's book is a treasure, a store of revelatory stories about how materiality, meaning, and myth have intertwined to create the aqueous spirits and deities that have accompanied human being and becoming.' - Stefan Helmreich, Elting E. Morison Professor of Anthropology, Massachusetts Institute of Technology
'A must-read' New Scientist 'Fascinating' Greta Thunberg 'Enthralling' George Monbiot 'Brilliant' Philip Hoare A thrilling investigation into the pioneering world of animal communication, where big data and artificial intelligence are changing our relationship with animals forever In 2015, wildlife filmmaker Tom Mustill was whale watching when a humpback breached onto his kayak and nearly killed him. After a video clip of the event went viral, Tom found himself inundated with theories about what happened. He became obsessed with trying to find out what the whale had been thinking and sometimes wished he could just ask it. In the process of making a film about his experience, he discovered that might not be such a crazy idea. This is a story about the pioneers in a new age of discovery, whose cutting-edge developments in natural science and technology are taking us to the brink of decoding animal communication - and whales, with their giant mammalian brains and sophisticated vocalisations, offer one of the most realistic opportunities for us to do so. Using 'underwater ears,' robotic fish, big data and machine intelligence, leading scientists and tech-entrepreneurs across the world are working to turn the fantasy of Dr Dolittle into a reality, upending much of what we know about these mysterious creatures. But what would it mean if we were to make contact? And with climate change threatening ever more species with extinction, would doing so alter our approach to the natural world? Enormously original and hugely entertaining, How to Speak Whale is an unforgettable look at how close we truly are to communicating with another species - and how doing so might change our world beyond recognition.
In 2006, vaquita, a diminutive porpoise making its home in the Upper Gulf of California, inherited the dubious title of world’s most endangered marine mammal. Nicknamed “panda of the sea” for its small size and beguiling facial markings, vaquita have been in decline for decades, dying by the hundreds in gillnets intended for the commercially valuable fish, totoaba. When international crime cartels discovered a lucrative trade in the swim bladders of totoaba, illegal gillnetting went rampant, and now the lives of the few remaining vaquita hang in the balance. Author Brooke Bessesen takes us on a journey to Mexico’s Upper Gulf region to uncover the story. She interviewed townspeople, fishermen, politicians, scientists, and activists, teasing apart a complex story filled with villains and heroes, a story whose outcome is unclear. When diplomatic and political efforts to save the little porpoise failed, Bessesen traveled with a team of veterinary experts in a binational effort to capture the remaining ten vaquita and breed them in captivity—the only hope for their survival. In this fast-paced, soul-searing tale, she learned that there are no easy answers when extinction is profitable. Whether the rescue attempt succeeds or fails, the world must ask itself hard questions. When vaquita and the totoaba are gone, the black market will turn to the next vulnerable species. What will we do then?
Touching This Leviathan asks how we might come to know the unknowable--in this case, whales, these animals so large yet so elusive, revealing just a sliver of back, a glimpse of a fluke, or, if you're lucky, a split-second breach before diving away. It's a pressing question, given how frequently whales are in the news: Japan just withdrew from the International Whaling Commission's ban on whaling; the Makah Tribe seeks to resume hunts; in 2019 there was a rash of dead gray whales along the west coast (some 200 of them); in 2018, an orca attracted international attention when she pushed her dead calf through the water 17 days before finally letting go. But other whale books sit in disciplinary silos: the history books, the science books, the literary books. There's no conversation between them, which is where Touching This Leviathan intervenes. Drawing upon biology, theology, local history, literary studies, environmental studies, and composition theory, Touching This Leviathan is necessarily interdisciplinary: literary nonfiction that gestures toward science and literary criticism as it invites readers into the belly of the whale.
Passive acoustic monitoring is increasingly used by the scientific community to study, survey and census marine mammals, especially cetaceans, many of which are easier to hear than to see. PAM is also used to support efforts to mitigate potential negative effects of human activities such as ship traffic, military and civilian sonar and offshore exploration. Walter Zimmer provides an integrated approach to PAM, combining physical principles, discussion of technical tools and application-oriented concepts of operations. Additionally, relevant information and tools necessary to assess existing and future PAM systems are presented, with Matlab code used to generate figures and results so readers can reproduce data and modify code to analyse the impact of changes. This allows the principles to be studied whilst discovering potential difficulties and side effects. Aimed at graduate students and researchers, the book provides all information and tools necessary to gain a comprehensive understanding of this interdisciplinary subject.
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.

Despite its remote and seemingly rigorous environment, the Antarctic is the world's most important habitat for seals, currently supporting more seals than all other parts of the world combined. As various national Antarctic programmes were established to study these animals, the need to standardize techniques became apparent. This book, arising from work by the Scientific Committee on Antarctic Research (Group of Specialists on Seals), gives a detailed account of well-tried and, where possible, agreed methodologies, techniques, procedures and rationale for the collection and initial analysis of data on the biology and population ecology of Antarctic seals. This volume will not only help facilitate comparisons between different regions of Antarctica, but will also provide a guide for those studying seals in other parts of the world and those carrying out research on other large mammal species.
A multitude of direct and indirect human influences have significantly altered the environmental conditions, composition, and diversity of marine communities. However, understanding and predicting the combined impacts of single and multiple stressors is particularly challenging because observed ecological feedbacks are underpinned by a number of physiological and behavioural responses that reflect stressor type, severity, and timing. Furthermore, integration between the traditional domains of physiology and ecology tends to be fragmented and focused towards the effects of a specific stressor or set of circumstances. This novel volume summarises the latest research in the physiological and ecological responses of marine species to a comprehensive range of marine stressors, including chemical and noise pollution, ocean acidification, hypoxia, UV radiation, thermal and salinity stress before providing a perspective on future outcomes for some of the most pressing environmental issues facing society today. Stressors in the Marine Environment synthesises the combined expertise of a range of international researchers, providing a truly interdisciplinary and accessible summary of the field. It is essential reading for graduate students as well as professional researchers in environmental physiology, ecology, marine biology, conservation biology, and marine resource management. It will also be of particular relevance and use to the regulatory agencies and authorities tasked with managing the marine environment, including social scientists and environmental economists.
For centuries whales have captured our imaginations and ignited our emotions. We have revered and mythologised them, hunted them to the brink of extinction and passionately protected them. But how much do we really know about whales? Based on the hugely popular, internationally touring exhibition Whales Tohora (a.k.a. Whales: Giants of the Deep), this all-new book brings these majestic marine mammals and their underwater world to life, with a special focus on the whales and dolphins of the South Pacific. From the first richly illustrated, entertaining chapter, readers are immersed in the salty sea, the home of the whales, to explore their amazing diversity, biology and adaption to life in the oceans. Throughout the book, literally hundreds of breath-taking photographs, historical pictures, astonishing facts and figures and informative illustrations and diagrams bring the whale world to life. Here, too, are stories from people whose lives have been inextricably linked with whales - from legendary South Pacific whale riders to international whale scientists to conservationists to former whalers and their families.Powerfully, Whales Tohora combines storytelling, science, and culture to tell the story of the relationship between the humans and these fascinating creatures throughout history and into the future.
There are fewer grey seals in the world than endangered African elephants, but the British Isles host almost half of this global population. Every year these charismatic animals, with their expressive eyes and whiskers more sensitive than our fingertips, haul out on our shores to breed and raise their pups. Susan Richardson has always been entranced by seals; they seem to have surfaced at key junctions throughout her life, comforting her as an anxious child, bringing joy as she began to spread her wings as a writer and helping her to find her way after the loss of her mother. Now she sets out to trace the rhythm of their lives, travelling the coasts clockwise from Cornwall to Norfolk, in line with the autumn pupping season. Along the way she explores the myths surrounding seals, from their shapeshifting selkie skins to the claims that they decimate fish populations, and she discovers that the greatest dangers they face come from co-existing with us. Brimming with vivid descriptions of the natural world, Where the Seals Sing is a lyrical tale of memory, rescue and rehabilitation. While loss, both personal and ecological, is a recurring theme, the human-seal connection that flows through the story is stirring and uplifting.
Providing a comprehensive account of marine conservation, this book examines human use and abuse of the world's seas and oceans and their marine life, and the various approaches to management and conservation. Healthy marine ecosystems - the goods and services that they provide - are of vital importance to human wellbeing. There is a pressing need for a global synthesis of marine conservation issues and approaches. This book covers conservation issues pertinent to major groups of marine organisms, such as sharks, marine turtles, seabirds and marine mammals; key habitats, from estuaries, wetlands and coral reefs to the deep sea; and from local and regional to international initiatives in marine conservation. An ideal resource for students, researchers and conservation professionals, the book pays appropriate attention to the underlying marine biology and oceanography and how human activities impact marine ecosystems, enabling the reader to fully understand the context of conservation action and its rationale.
Analysing the physiological adaptations of marine mammals and seabirds, this book provides a comprehensive overview of what allows these species to overcome the challenges of diving to depth on a single breath of air. Through comparative reviews of texts on diving physiology and behaviour from the last seventy-five years, Ponganis combines this research into one succinct volume. Investigating the diving performance of marine mammals and seabirds, this book illustrates how physiological processes to extreme hypoxia and pressure are relevant to the advancement of our understanding of basic cellular processes and human pathologies. This book underscores the biomedical and ecological relevance of the anatomical, physiological and molecular/biophysical adaptations of these animals to enable further research in this area. An important resource for students and researchers, this text not only provides an essential overview of recent research in the field, but will stimulate further research into the behaviour and physiology of diving.
