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.

The collaboration of two friends—one a novelist, one a marine biologist—produced a volume in which fascinating popular science is woven into a narrative of man’s dreams, his ideals, and his accomplishments through the centuries. Sea of Cortez is one of those rare books that are all things to all readers. Actually the record of a brief collecting expedition in the lonely Gulf of California, it will be science to the scientist, philosophy to the philosopher, and to the average man an adventure in living and thinking. The teeming and wildly competitive world of the sand flats is seen in terms of history, politics, ethics, and sociology; a starfish is important, not only because it is a new variety, but because it is essential to the delicate balance of the whole region in which it is found. Steinbeck and Ricketts are the opposite of “pure” scientists: it is not only their work that fascinates them, but the complicated and enormously exciting implications of that work. Sea of Cortez is a book to be read and remembered on two levels. It is a journey through a remote and beautiful corner of the world, a diary filled with the daily excitements and triumphs of skillful and energetic men. It is also an invitation to see the world anew from a fresh vantage point and perhaps with a broader and more understanding spirit.
