First published in 1992, this guide has been significantly expanded in a new 3rd edition. The popular, user-friendly field guide, covering all major groups of marine invertebrates encountered by divers on coral reefs and adjacent habitats, has grown to include 900 species beautifully documented with more than 1200 underwater photographs -- nearly doubling the total in the previous editions. Les Wilk has joined Paul Humann and Ned DeLoach authoring the comprehensive new edition.

Northern Fishes was first published in 1974. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. With the greatly increased interest in fishes and fishing since the earlier editions of this work were published, there has been need for a revised version of this indispensable book on the fishes of the Upper Mississippi Valley. This, the third edition, revised, of Northern Fishes by Samuel Eddy and Thaddeus Surber, contains much new material and up-to-date information based on current knowledge about fishes, their environment, and fishing techniques. The book covers more than 160 species with descriptions and line drawings to illustrate almost all of them. The authors discuss recently introduced species and their importance to sportsmen and provide current data on the distribution of northern fishes. There are keys for the identification of the species and information about where they are found and their habits. This edition also contains a number of additions to the species list which result from rather extensive collecting of specimens since the earlier editions were compiled. Before presenting the data on individual species, the authors provide basic information about fishes in general-their structure, classification and origin, their food, and their parasites. The revised, updated section on fishing techniques includes information about spin casting. There are important chapters on lake dynamics, fish population dynamics, management of Minnesota and northern waters for fish production, and improvement of lakes and streams. The detailed information about species is arranged according to families. For further reading or reference there is a bibliography.

From Flipper to SeaWorld, dolphins have long captured our hearts. We love these friendly, intelligent mammals, and they seem to return our feelings--they enjoy interacting with swimmers and have been known to encircle people under attack by sharks. Despite our familiarity with dolphins, though, we remain ill-informed about how they evolved, how they function and how they have interacted with humans for millennia. Dolphin dives into the dolphin's zoology, as well as its social and cultural history, to offer a comprehensive view of these delightful creatures. Drawing on his years of experience working with and studying dolphins, Alan Rauch explores their propensity to live in pods and their ability to communicate through a variety of clicks, whistles and other vocalizations. He examines their long relationship with humans, describing how they became the emblem of safe travel and charity, that the ancient Greeks featured them on coins and that Hindu mythology associated them with Ganga, a river deity. As the rise in popularity of dolphinaria during the 1960s allowed the public access to dolphins, they became central characters in films like The Day of the Dolphin and Johnny Mnemonic and outsmarted humans in The Hitchhiker's Guide to the Galaxy. Packed with images and thoughtful insights, Dolphin is a revealing look at one of our favorite sea creatures.

From the more than one million square miles of the six eastern provinces of Canada 154 species of freshwater fishes have been reported. This edition of Freshwater Fishes of Canada provides the game and commercial fisherman and the naturalist with detailed information regarding these fishes, and assists in the accurate identification of the various species. The species are arranged in order of development: primitive first and the more highly specialized fishes last. Each description includes a picture, a list of other common names, the distinguishing features, size, habitat, life history and habits, food, and additional comments. Technical language has been avoided wherever possible but with no loss of accuracy. In this second edition the author has employed a system of keys for easier identification of families, and of the individuals in the two largest and most difficult species, the trout and minnow groups.

Humans aside, dolphins, whales, and porpoises are often considered to be the smartest creatures on Earth. Science and nature buffs are drawn to stories of their use of tools, their self-recognition, their beautiful and complex songs, and their intricate societies. But how do we know what we know, and what does it mean? In Deep Thinkers, renowned cetacean biologist Janet Mann gathers a gam of the world's leading whale and dolphin researchers--including Luke Rendell, Hal Whitehead, and many more--to illuminate these vital questions, exploring the astounding capacities of cetacean brains. Diving into our current understanding of and dynamic research on dolphin and whale cognition, communication, and culture, Deep Thinkers reveals how incredibly sophisticated these mammals are--and how much we can learn about other animal minds by studying cetacean behavior. Through a combination of fascinating text and more than 150 beautiful and informative illustrations, chapters compare the intelligence markers of cetaceans with those of birds, bats, and primates, asking how we might properly define intelligence in nonhumans. As all-encompassing and profound as the seas in which these deep cetacean cultures have evolved, Deep Thinkers is an awesome and inspiring journey into the fathoms--a reminder of what we gain through their close study, and of what we lose when the great minds of the sea disappear.

"A pleasant, chatty book on a fascinating subject." --" Kirkus Reviews"
Octopuses have been captivating humans for as long as we have been catching them. Yet for all of our ancient fascination and modern research, we still have not been able to get a firm grasp on these enigmatic creatures.
Katherine Harmon Courage dives into the mystifying underwater world of the octopus and reports on her research around the world. She reveals, for instance, that the oldest known octopus lived before the first dinosaurs; that two thirds of an octopus's brain capacity is spread throughout its arms, meaning each literally has a mind of its own; and that it can change colors within milliseconds to camouflage itself, yet appears to be colorblind.

In "Dancing with Your Dark Horse, " Chris Irwin, world-renowned as one of the most successful horse whisperers in North America, further explores the intriguing spiritual connection he has discovered between human and equine nature. Based on his more than twenty years of working with, training, and observing horses, Irwin explains how the characteristics necessary to building good relationships with horses can in turn be used to establish a positive balance between mind, body, and spirit in our own lives. "Dancing with Your Dark Horse" will help readers see that horses have a great deal to teach us about how to live happier, healthier, and more balanced lives.

The Reef Coral Identification Florida Caribbean Bahamas by Paul Humann and Ned DeLoach, originally published in 1993, is the most comprehensive field guide ever compiled for the visual identification of corals and marine plants of the region. The new 3rd edition includes additional photographs documenting new species and growth variations. The expanded text incorporates the most current scientific research, including updated information about the diseases and reproductive behavior of corals.

For centuries, the fates of people living along the east coast of Canada and the United States have been tied to the fishery and the harvesting of the northwest Atlantic began long before Europeans first settles these shores. Today, overfishing and a changing ocean environment threaten many fish stocks. Yet despite the many ongoing challenges the fishing industry persists, still central to the economic well-being of North America. It is also at the core of cultural identity from Newfoundland and Labrador to the Eastern Seaboard. Heres the Catch celebrates the finfish species that are the reason many communities remain linked to the northwest Atlantic Ocean. It also explores what could be lost or gained from this historic resource in the coming years depending on our actions. Do we continue to undermine this vast ecosystem? Or will we manage it and the fishery in ways that allow these fish stocks to once again flourish? In the foreword, renowned fisheries scientist George Rose is cautiously optimistic about the future. For his part, author Wade Kearley provides a wealth of detail about the astonishing variety of fish we harvest from the sea, giving you insight into the complexity of factors affecting the health of both the fish and the fishey.

Mysterious Manatees is a synergistic partnership between photographer Karen Glaser and writer and scholar John Reynolds, two of the nation's leading interpreters - one artistic, one scientific - of the life and underwater habitat of the manatee. This union of science and art makes for a compelling exploration of the manatee through two independent essays - one textual, one visual - in a book addressed to both specialists and a general audience. To some, an emblem of the tranquility and beauty of natural Florida, to others an obstacle to fast-track growth and good times, the endangered Florida manatee arouses the passions of those who have encountered it and the curiosity of those who have only heard about this huge, enigmatic inhabitant of Florida's coastal waterways. The book opens with Reynolds's scientific account of the interactions between people and manatees, describing the history of manatee hunting, relating what is known about their early distribution and survival, and clarifying the debate about whether manatees are native to Florida. Reynolds also discusses manatee biology and the features that make the animal especially vulnerable to human activities. Reynolds's complete and authoritative account of manatee biology, management, and conservation concludes with a gallery of plates featuring Glaser's remarkable panoramic photographs. Glaser's 52 beautiful duotone prints capture an intimate, distinctively natural vision of manatees in their own environment, an underwater world illuminated only by the sunlight above. The manatees were photographed in all the diverse conditions that comprise their environment: mud, muck, clear water, rain, sunny or cloudy - all illuminate the forms of these magnificent animals. Mysterious Manatees will appeal to wildlife professionals, amateur naturalists, environmentalists, and lovers of fine photography as a unique combination of fact and image that provides a compelling sense of the mysterious presence of these large yet gentle and graceful sea creatures.

Introduces readers to the roles of sharks in ocean ecosystems, as well as threats to shark populations and conservation efforts. Eye-catching infographics, clear text, and a "That's Amazing!" feature make this book an engaging exploration of the importance of sharks.

This book brings alive the richly diverse world of an underwater paradise: the Mesoamerican Barrier Reef. Stretching 625 miles through the Caribbean Sea along the coasts of Mexico, Belize, Guatemala, and Honduras, this reef is the second largest coral structure on the planet. Imperiled Reef searches out the breathtaking intricacies of this endangered ecological treasure. Sandy Sheehy describes in eloquent detail the hard and soft corals, sponges, and myriad marine creatures-from sea turtles to jellyfish to dolphins-that interact to form a delicately balanced interdependent ecosystem, as well as the culturally diverse human communities that depend on them. She explores the work of marine biologists, oceanographers, and ecologists who have devoted their lives to studying this unique environment. Research shows that the future of the reef is at risk, Sheehy explains. Looking closely at threats ranging from global warming to overfishing to irresponsible development, Sheehy draws attention to the inspiring efforts of nongovernmental agencies, scientists, and local communities who are working together to address these challenges. She includes practical actions individuals can take to protect this reef-as well as marine ecosystems everywhere. Celebrating a vast, submerged landscape that has too often been undervalued, Imperiled Reef is both a strong case for protecting an international marvel and a powerful message of hope for the world's oceans.

In Search of Monster Fish is an action-packed, knee-slapping ride into and out of the belly of the beast. Join extreme angler Mark Spitzer as he encounters man-eating catfish, ruthless barracuda, lacerating conger eels, berserk tarpon, and blood-curdling sharks in locales as exotic as the Amazon, Catalonia, the Dominican Republic, Senegal, and even in our own backyards. But this eco-odyssey isn't just about meeting and releasing some of the most grotesque lunkers in the world. It's about implementing solutions for problems as behemoth as global warming and issues as common as choosing what to eat for dinner. And as the ice caps melt at the rate of 1 percent annually, Spitzer battles his most epic goliath: a leviathan that dwells in the depths of us all, making us ask who the real monsters are, what our responsibilities truly are, and what we can possibly do to sustain our planet and ourselves when faced with such demonic disenlightenment. Spitzer then beats this whopper into submission by reframing his call to action and finding his own way. A new portal to the underworld has been opened in the cutting-edge literature of monster fish, and this is your entry ticket.

The fresh waters of the British Isles are diverse, ranging from torrential hill streams to powerful rivers and wide, meandering lowland channels. Canals and drainage channels, ranging in size from ditches to the large Fenland drains of eastern England also hold fish, as do reservoirs, lakes, ponds and other still water bodies. The fish themselves are correspondingly varied. This pocket-sized book provides information about the 54 native, invasive and naturalised species found in the UK today, and includes a photograph of each to allow easy identification

An engaging account of the natural history of rock and boulder-strewn shores around Britain's coastline Rocky Shores explores the species, communities and landscape of the narrow strip of land surrounding much of the British Isles. While it may be limited in extent, this habitat is incredibly biodiverse, and this insightful book details all the patterns of marine life that might be encountered on sheltered and exposed shores, from the inhospitable splash zone to the repeatedly submerged lower shore, and everything in between. Comprehensive chapters accompanied by exceptional photographs cover various members of the rocky-shore community in turn: striking lichens that colourfully adorn the rocks; seaweeds that have sustained human settlements for millennia; mysterious and often spectacular worms and their relatives; molluscs with variously configured shells; spiny-skinned echinoderms that move using tube feet; arthropods that range from tiny marine insects to heavy-clawed crabs; and microscopic species that drift around at the mercy of the tides. Rock pools provide pockets of diversity dotted across the shore, while the strandline at the high-tide mark supports a unique assemblage of microbes and invertebrates that attracts a variety of birds and mammals. For anyone with a love of the shore - from the occasional rockpooler to avid naturalists - this book is a must for your collection.

At once feared and revered, sharks have captivated people since our earliest human encounters. Children and adults alike stand awed before aquarium shark tanks, fascinated by the giant teeth and unnerving eyes. And no swim in the ocean is undertaken without a slight shiver of anxiety about the very real - and very cinematic - dangers of shark bites. But our interactions with sharks are not entirely one-sided: the threats we pose to sharks through fisheries, organized hunts, and gill nets on coastlines are more deadly and far-reaching than any bite. A contributing photographer to National Geographic, Thomas P. Peschak is best known for his unusual photographs of sharks - his iconic image of a great white shark following a researcher in a small yellow kayak is one of the most recognizable shark photographs in the world. The other images gathered here are no less riveting, bringing us as close as possible to sharks in the wild. Alongside the photographs, Sharks and People tells the compelling story of the natural history of sharks. Sharks have roamed the oceans for more than four hundred million years, and in this time they have never stopped adapting to the ever-changing world-their unique cartilage skeletons and array of super-senses mark them as one of the most evolved groups of animals. Scientists have recently discovered that sharks play an important role in balancing the ocean, including maintaining the health of coral reefs. Yet, tens of millions of sharks are killed every year just to fill the demand for shark fin soup alone. Today more than sixty species of sharks, including hammerhead, mako, and oceanic white-tip sharks, are listed as vulnerable or in danger of extinction. The need to understand the significant part sharks play in the oceanic ecosystem has never been so urgent, and Peschak's photographs bear witness to the thrilling strength and unique attraction of sharks. They are certain to enthrall and inspire. In Sharks and People acclaimed wildlife photographer Thomas Peschak presents stunning photographs that capture the relationship between people and sharks around the globe.

"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.

Whales are the largest animals ever to have lived on the earth: the longest recorded was over 33 metres long, the heaviest more than 171,000 kgs; a large Blue Whale's tongue alone can weigh more than an elephant. Whales can stay underwater for more than an hour, some speculate that they can live for up to 200 years, and they are among the most intelligent animals known to humanity. "Whale" recounts the evolutionary and ecological background, as well as the cultural history, of these extraordinary mammals, long persecuted and now celebrated throughout the world. From the tales of Jonah and Brendan the Navigator to Moby Dick and recent discoveries of cetacean songs and culture, Joe Roman looks at the role of the whale in human history, mythology, art, literature, commerce and science. Illustrated with Stone Age carvings, medieval broadsheets and colour underwater photographs, "Whale" shows how our perception of these animals has changed over the centuries: a hundred years ago, a stranded whale was usually greeted with flensing knives; now people bring boats and harnesses to return a wayward creature to the sea. Written by an author with vast experience of the subject, "Whale" will appeal to all those interested in whales and the conservation of the oceans, as well as anyone studying cultural history and the natural sciences.

Wild dolphins are an elusive subject. How can you study the behaviour of animals usually visible only as a glimpse of rolling dorsal fins heading for the horizon? Two scientists in the field have assembled a variety of discoveries about dolphins, from tiny spinners to familiar bottle-nosed dolphins, and their whale cousins, including pilot and killer whales. The researchers have followed dolphins in boats, tracked them from shore, dived among them, and used genetic analysis and artificial language to read their life history from a single tooth. This text not only surveys interesting research on dolphin behaviour, but it also offers lay readers a look at the scientific mind at work.
