De una de las nadadoras profesionales mas destacadas del mundo nos llega este maravilloso relato, sobre el poder de la fe que supera todos los obstaculos
En "Grayson," Lynne Cox narra la historia de un milagroso e inolvidable encuentro que vivio en el mar a los diecisiete anos. En una madrugada serena pero cargada de energia, Lynne nadaba en aguas frias, a doscientos metros de la costa, cuando se percato de que algo nadaba por debajo de ella. Aquello parecia lo bastante grande como para ser un tiburon blanco, pero no lo fue.
Resulto ser un bebe ballena que habia perdido a su mama en el mar, y que habia seguido a Lynne por mas de una milla. Si Lynne no lograba encontrar a la mama, el bebe ballena se deshidrataria y moriria de hambre. Algo tan enorme como la mama ballena, que media quince metros, de pronto parecia muy pequena en el vasto oceano Pacifico. Como podria encontrarla Lynne?

Published in 1974, these symposia proceedings examine the management of trout habitat in mountain streams. Conservation organizations, researchers, and land managers, discussed trout habitat management programs and policies. They also identified management problems and present and explored future needs.

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.

"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.

Powerful and mysterious, sharks inspire both fascination and fear. Worldwide, oceans are home to some five-hundred species, and of those, fifty-six are known to reside in or pass through the waters off the coast of both North and South Carolina. At any given time, waders, swimmers, and surfers enjoying these waters are frequently within just one-hundred feet of a shark. While it's unnerving to know that sharks often swim just below the surface in the shallows, Clay Creswell, a shark-bite investigator for the Shark Research Institute's Global Shark Attack File, explains that attacks on humans are extremely rare. In 2019 the International Shark Attack File confirmed sixty-four unprovoked attacks on humans, including three in North Carolina and one in South Carolina. While acknowledging that they pose real dangers to humans, Creswell believes the fear of sharks is greatly exaggerated. During his sixteen-year association with the Shark Research Institute, he has investigated more than one hundred shark-related incidents and has maintained a database of all shark-human encounters along the Carolina coastlines back to 1817. Creswell uses this data to expose the truth and history of this often-sensationalized topic. Beyond the statistics related to attacks in the Carolina waters, Sharks in the Shallows offers a history of shark-human interactions and an introduction to the world of shark attacks. Creswell details the conditions that increase a person's chances of an encounter, profiles the three species most often involved in attacks, and reveals the months and time of day with the highest probability of an encounter. With a better understanding of sharks' responses to their environment, and what motivates them to attack humans, he hopes people will develop a greater appreciation of the invaluable role sharks play in our marine environment.

From his childhood fascination with the gigantic Natural History Museum model of a blue whale, to his abiding love of "Moby-Dick," to his adult encounters with the living animals in the Atlantic Ocean, the acclaimed writer Philip Hoare has been obsessed with whales. "The Whale" is his unforgettable and moving attempt to explain why these strange and beautiful animals exert such a powerful hold on our imagination.

Famed marine researcher and illustrator Richard Ellis brings us a work of scientific achievement that will forever change the way we think about fish, fishing, and the dangers inherent in the seafood we eat.
The bluefin tuna is one of the world's biggest, fastest, and most highly evolved marine animals, as well as one of its most popular delicacies. Now, however, it hovers on the brink of extinction. Here Ellis explains how a fish that was once able to thrive has become a commodity--and how the natural world and the global economy converge on our plates. With updated information on mercury levels in tuna, this is at once an astounding ode to one of nature's greatest marvels and a serious examination of a creature and world at risk.

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.

The world's nearly 7,000 species of crabs are immediately recognizable by their claws, sideways movement, stalked eyes, and thick outer shells. These common crustaceans are found internationally, thriving in various habitats from the edge of the sea to the depths of the ocean, in fresh water or on land. Despite having the same basic body type as decapod crustaceans true crabs have heavy exoskeletons and ten limbs with front pincer claws crabs come in an enormous variety of shapes and sizes, from the near microscopic to the giant Japanese spider crab.

In Walking Sideways, Judith S. Weis provides an engaging and informative tour of the remarkable world of crabs, highlighting their unique biology and natural history. She introduces us to recently discovered crabs such as the Yeti crab found in deep sea vents, explains what scientists are learning about blue and hermit crabs commonly found at the shore, and gives us insight into the lifecycles of the king and Dungeness crabs typically seen only on dinner plates. Among the topics Weis covers are the evolution and classification of crabs, their habitats, unique adaptations to water and land, reproduction and development, behavior, ecology, and threats, including up-to-date research.

Crabs are of special interest to biologists for their communication behaviors, sexual dimorphism, and use of chemical stimuli and touch receptors, and Weis explains the importance of new scientific discoveries. In addition to the traditional ten-legged crabs, the book also treats those that appear eight-legged, including hermit crabs, king crabs, and sand crabs. Sidebars address topics of special interest, such as the relationship of lobsters to crabs and medical uses of compounds derived from horseshoe crabs (which aren't really crabs).

While Weis emphasizes conservation and the threats that crabs face, she also addresses the use of crabs as food (detailing how crabs are caught and cooked) and their commercial value from fisheries and aquaculture. She highlights other interactions between crabs and people, including keeping hermit crabs as pets or studying marine species in the laboratory and field. Reminding us of characters such as The Little Mermaid's Sebastian and Sherman Lagoon s Hawthorne, she also surveys the role of crabs in literature (for both children and adults), film, and television, as well in mythology and astrology. With illustrations that offer delightful visual evidence of crab diversity and their unique behaviors, Walking Sideways will appeal to anyone who has encountered these fascinating animals on the beach, at an aquarium, or in the kitchen.

This is the first guide to finding and observing Hawaiian green turtles, or honu. It describes an exciting journey of discovery undertaken by two avid sports divers, Peter Bennett and Ursula Keuper-Bennett, who encountered their first honu twenty years ago while diving off Honokowai, Maui. The Bennetts soon realized that many honu (and green turtles worldwide) were afflicted with debilitating and potentially deadly tumors. They began to document the disease using photographs and videotape and in the process educated themselves about the daily lives of honu. To their surprise, they discovered they were the first to make prolonged observations of a marine turtle population in its natural habitat.Drawing on their extensive experience, the Bennetts explain how to find and watch honu from shore and while snorkeling, kayaking, and especially diving. They describe the behaviors they have documented over the years and what they might mean. Their rich collection of photographs will introduce readers to honu not only as a species, but also as individual animals whose histories they have closely followed and recorded.Thanks to a highly successful conservation and research program and protection granted by the U. S. Endangered Species Act, encounters between sea turtles and humans in Hawai'i have become common. Accessibly written and extensively illustrated, ""The Book of Honu"" will alert turtle enthusiasts and others on what to expect when they come across these gentle creatures and how to observe them respectfully.
