Few places in the world can claim such a diversity of species as the Gulf of California (Sea of Cortez), with its 6,000 recorded animal species estimated to be half the number actually living in its waters. So rich are the Gulf's water that over a half-million tons of seafood are taken from them annuallyÑand this figure does not count the wasted by-catch, which would triple or quadruple that tonnage. This timely book provides a benchmark for understanding the Gulf's extraordinary diversity, how it is threatened, and in what ways it isÑor should beÑprotected. In spite of its dazzling richness, most of the Gulf's coastline now harbors but a pale shadow of the diversity that existed just a half-century ago. Recommendations based on sound, careful science must guide Mexico in moving forward to protect the Gulf of California. This edited volume contains contributions by twenty-four Gulf of California experts, from both sides of the U.S.-Mexico border. From the origins of the Gulf to its physical and chemical characteristics, from urgently needed conservation alternatives for fisheries and the entire Gulf ecosystem to information about its invertebrates, fishes, cetaceans, and sea turtles, this thought-provoking book provides new insights and clear paths to achieve sustainable use solidly based on robust science. The interdisciplinary, international cooperation involved in creating this much-needed collection provides a model for achieving success in answering critically important questions about a precious but rapidly disappearing ecological treasure.

First published in 1979, this guide has become the standard resource for scientists, divers, and spearfishers interested in the fishes of the tropical Pacific Coast. The authors have revised and updated this edition to include the most current taxonomic information, additional species descriptions, and new illustrations.

Comprehensive manual for understanding and carrying out marine mammal rescue activities for stranded seals, manatees, dolphins, whales, or sea otters.

Learning marine biology from a textbook is one thing. But take readers to the bottom of the sea in a submarine to discover living fossils or to coral reefs to observe a day in the life of an octopus, and the sea and its splendors come into focus, in brilliant colors and with immediacy. In Sensuous Seas, Eugene Kaplan offers readers an irresistibly irreverent voyage to the world of sea creatures, with a look at their habitats, their beauty and, yes, even their sex lives. A marine biologist who has built fish farms in Africa and established a marine laboratory in Jamaica, Kaplan takes us to oceans across the world to experience the lives of their inhabitants, from the horribly grotesque to the exquisitely beautiful. In chapters with titles such as "Fiddler on the Root" (reproductive rituals of fiddler crabs) and "Size Does Count" (why barnacles have the largest penis, comparatively, in the animal kingdom), Kaplan ventures inside coral reefs to study mating parrotfish; dives 740 feet in a submarine to find living fossils; explains what results from swallowing a piece of living octopus tentacle; and describes a shark attack on a friend. The book is a sensuous blend of sparkling prose and 150 beautiful illustrations that clarify the science. Each chapter opens with an exciting personal anecdote that leads into the scientific exploration of a distinct inhabitant of the sea world--allowing the reader to experience firsthand the incredible complexity of sea life. A one-of-a-kind memoir that unfolds in remarkable reaches of ocean few of us can ever visit for ourselves, Sensuous Seas brings the underwater world back to living room and classroom alike. Readers will be surprised at how much marine biology they have learned while being amused.

Artists’ book. Original volume has had cover enhanced with etching and gouache on front and back covers, and monoprints of sea life on end papers.

Perspective of This Volume Charles Darwin brought the Galapagos Islands to the attention of zoologists, botanists, and geologists following the six-week visit of H. M. S. Beagle to the islands in 1835. Since then published research on the biota of the islands, partic ularly in multiauthored volumes, has focused on terrestrial plants and animals. The present volume is designed specifically to provide a summary of work on the marine invertebrate fauna. One deviation from that objective was the inclusion of a chapter on land snails, which proved to be a good choice because the phylum Mollusca is now covered more thoroughly in this volume than in any single previous scholarly work on the Galapagos. The academic bottom line with this book is to elucidate the evolutionary responses of shallow water, benthic marine invertebrates to the unique set of insular conditions that exist in the Galapagos Islands. The route taken to that objective has many paths including taxonomic revision, determining biogeo graphic affinities, and examining the ecological requirements of species. The information presented here is for some groups from the islands the first stage in a thorough process that can eventually lead to an understanding of the phylogenetic relationships of these species.
