An illustrated look at the weird and wonderful creatures that live in the very deepest parts of the sea. Humans have always wondered, with a mixture of fear and fascination, what lurks beneath the surface in the depths of the ocean. In this book, Erich Hoyt introduces 50 of the oddest creatures you will ever meet in the sea. From the carnivorous comb jelly to the lantern-carrying deep-sea dragonfish, from a vampire squid with giant eyes to dancing jellyfish, Hoyt explores these peculiar conditions and their equally peculiar environment. These creatures have adapted to lack of light and, using sound pulses (echolocation) or light-producing organs and pigment cells (emitting light via bioluminescence), they are able to communicate without giving their location away to predators. These stunning, captivating photographs weren't taken from the portholes of submarines. Photographers David Shale, Solvin Zanki and Jeff Rotman worked with oceanography institutes, museums and the BBC Natural History Unit, taking long cruises across the ocean to record and try to understand these little-studied residents of the deep sea. To capture the creatures for observation, a net was lowered far beneath the surface. As soon as the trawl was hauled aboard, the photographers would race to transfer the most unusual animals to fresh seawater aquariums in a chilled laboratory on board. These pages let readers gaze into strange, wild eyes and study faces with toothless or crooked smiles that witness the fruits of deep-sea evolution. Informative captions explain what the patterns of lights on their bodies are "saying" to others in their absolutely dark world. The wonder and extraordinary weirdness of what lives in the deep seas, so far away from us and yet so close, will become more familiar with this book.
Erich Hoyt's handbook is an admirable, timely and highly welcome contribution.'Michael Stachowitsch, Marine EcologyWhat does it mean to save the whales if their habitat is left unprotected? Marine Protected Areas for Whales, Dolphins and Porpoises is the definitive handbook on this pressing issue and the first to bridge the gap between the disciplines of marine protected areas and cetacean conservation. It launches a new chapter in cetacean conservation with its investigation into the crucial habitat needs and protection requirements of some 84 species.The author, one of the world's foremost experts in this field, takes you around the world to investigate the promising results of the latest conservation research and the strategies for obtaining marine protected areas in coastal waters and on the high seas, using national legislation and regional and international conventions. This is an essential introduction, guide and reference work for those working to ensure a future for whales and dolphins.
After seven summers of following these intelligent and playful creatures in the waters off northern Vancouver Island with his colleagues, Erich Hoyt gives the latest world-catch and live-capture statistics of killer wales, as well as updated records of those kept captive.
Elaborates an ethic in which beneficence on a personal and communal level has moral force; proposes the idea of an interplay between compassion and reason to help address moral problems; and sketches the conditions necessary for a democratic approach to such problems.
The focus of this volume differs from what is suggested by the series title, for it is on muscle contraction and movement rather than on behavior. The lone overnight flight of a ruby-throated hummingbird across the Gulf of Mexico is a migratory behavior mediated through an incredibly lengthy, repetitive series of wing move ments, each movement being produced by a complex sequence of muscle contrac tions. It is significant that these same movements may be used to mediate other behaviors, and that these same muscle contractions, in different sequence, may be used to produce other movements. The immense journey of white-bearded gnus across the Serengeti plains to suitable calving grounds is likewise a migratory behavior mediated through rather more varied, yet repetitive, limb movements, each produced by a complex sequence of muscle contractions. Again, these same movements may be used to mediate other behaviors, and again, the details of each limb movement may be varied through variations in the strength and the sequence of muscle contractions. A laboratory rat may learn to perform an escape behavior in a shuttle box, bringing its performance to a high level of efficiency by modifying its movement on successive trials. After intraperitoneal injection of pentobarbital sodium in an amount sufficient to render the animal severely incoordinated, the escape behavior is still performed, albeit through a different sequence of move ments, even to "rolling" out of the compartment in response to the warning signal.
Merrill, who urged a unique vision of reality that shaped a Mormon eschatology. He shows how authorities eventually retreated from the perception of reality as "true" and adopted a scientifically less secure position in order to protect their theology, an eventuality which ultimately resulted in a reactionary response to science within Mormonism.
An encyclopedic summary of the highlights in the field of free radicals in medicine and biology, with a detailed analysis of the extensive recent literature. The text describes results from experimental research work on dust inhalation, hypoxia, and environmental toxicology that uses morphologic methods such as electron microscopy, interference microscopy and time-lapse technqiues in tissue cultures. The volume discusses free radical reactions that are probably involved in the pathogenesis of both physical and chemical environmental hazards. It lists radical scavengers that function as useful prophylactic agents in case of unavoidable exposure. A short history of dust diseases that have challenged mankind since prehistoric times serves as an introduction to this comprehensive treatise. It is hoped that by covering this field in one monograph, the increasingly recognized and important role of both oxygen- and nitrogen-centred radicals in disease pathogenesis will become clearer. The enclosed CD includes nearly 25.000 literature citations useful as a reference source for researchers, clinicians and students.
Includes descriptions of species, places throughout the world to go to watch whales, lookout sites, tours available, weather/sea notes and museums etc. Also includes list of photographic equipment, clothing and useful items for whale watching.
This book brings us up to date on the latest dolphin research, answering and asking questions about the future of their threatened habitat, social lives, feeding behaviours and ability to learn from and communicate with humans.
Presents an alphabetically arranged reference guide to terms and issues relating to plant and animal extinction, and lists laws, government agencies, and public interest organizations that deal with biological extinction.
The first edition of the widely praised Marine Protected Areas for Whales, Dolphins and Porpoises, published in 2005, led to numerous new marine protected area proposals and a number of notable conservation successes around the world. In this completely revised and expanded second edition, new developments in the Mediterranean, Caribbean and Pacific are described, as well as future directions for High Seas protection. New sections show how to design and manage MPAs in an ever noisier ocean subject to climate change, increased shipping and hydrocarbon exploration. The process of protected area creation for cetaceans has been accelerated and more than 200 exciting new places are detailed in this edition. This book provides a route map for MPA managers, as well as countries, to meet the ambitious targets for highly protected MPA networks by 2012 and 2020. This book is a key conservation tool and a springboard for worldwide change in human attitudes toward the world ocean where all life originated and where the majority of life on Earth still lives.
Hoyt's passionate sense of kinship with orca makes his account effective as both a science and literature. He has chronicled his adventures and discoveries ...with grace, insight, wit--and a comprehensiveness that might satisfy even Herman Melville."("Discover Magazine) Star performers in aquariums and marine parks, killer whales were once considered to be too dangerous to approach in the wild. Erich Hoyt and his colleagues spent seven summers following these intelligent and playful creatures in the waters off northern Vancouver Island, intent on dispelling the killer myth. Orca: The Whale Called Killer is Hoyt's exciting account of those summers of adventure and discovery, and the definitive, classic work on the orca or killer whale. The "Free Willy films, inspired in part by Hoyt's pioneering writing about orcas, tell the story of a captive orca being returned to the wild. (Hoyt, in fact, recommended Keiko, the orca who became the star of "Free Willy, to Warner Bros.) But Orca: The Whale Called Killer tells the true story of wild orcas befriending humans.

When people hear the word "migration," they think of animals that move from a feeding area to a breeding area and back each year. But the greatest migration on Earth happens twice every night. The movement is largely vertical and performed by plankton followed by predatory fish, squid, octopus and other species that have acquired a taste for plankton. The migration starts deep in the waters of the ocean at sunset. As they move, the plankton nibble on plant plankton and other tasty morsels in the water and, eventually, some on each other. The feeding ends just before dawn when the plankton retreat to the depths of the ocean to hide during the day until the next evening, when they migrate back up the water column. In Planktonia, Erich Hoyt invites readers to dive into the dazzling nighttime ocean. Countless microscopic plankton -- larval creatures such as ornate ghost pipefish, left-handed hermit crabs and bony-eared assfish -- ascend to the upper waters to feed, returning to the depths before sunrise. These tiny planktonic creatures are delicate and beautiful; some look terrifying; and most look nothing like the creatures they will become as adults. This great vertical migration attracts larger adult creatures, too, from the solitary 6-inch (15 cm) bigfin reef squid and the fierce and hungry 6 1/2 foot (2 m) female blanket octopus, which is up to 40,000 times heavier than her male mate. Everyone comes here for the midnight feast, and they are all ravenously hungry. Chapters in this book include: Hawai'i: From Bluewater to Blackwater Awesome Anilao The Gulf Stream Procession of Life Blackwater White Sea Precious Life of Plankton Blackwater Unlimited From Blackwater Passion to Protection. All life in the ocean depends on plankton. Plankton plays a key role in sequestering carbon against climate change. The great nightly vertical migration highlights the importance of protecting not only ocean species but also ecosystems that embrace ocean processes from the depths of the sea to surface waters.
