Book Description
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.

Book Description
"In the realm of ichthyological literature, it would be hard to find more fascinating creatures than the football fishes, pugnose dreamers, mischievous dreamers, and snaggletooth seadevils, (not to mention triplewart, needlebeard, and whipnose seadevils), but they're all here in Oceanic Anglerfishes. In this comprehensive study, you will learn that most of the species are smaller than your hand; most have a bioluminescent lure that may be employed to attract prey into gobbling range; and that the relatively tiny males affix themselves to the females, assuring permanent sexual contact in the blackness of the depths. This is a brilliantly illuminated viewing port into the world of deep-sea creatures, bringing into sharp focus fishes whose weird appearance, habits, and lifestyles stretch the imagination to the point of near unbelievability."--Richard Ellis, author of The Book of Sharks and Encyclopedia of the Sea "Ceratioid anglerfishes are classical deep-sea fishes that display a vast array of bizarre and wonderful behaviors and associated morphological adaptations that are almost beyond our ability to imagine. Their first dorsal fin spine has been modified into a fishing rod (the illicium) ending in a fleshy bait (the esca) and they show extreme sexual dimorphism with tiny males with huge nostrils and modified pincer-like jaws to attach themselves to a female, sometimes permanently. Ted Pietsch describes in great detail the 11 families, 35 genera, and 160 known species of deep-sea anglerfishes in his splendidly illustrated monograph based on research that began with finding the first ceratioid washed ashore in Greenland in 1833 and continues through Pietsch's 40-year career of studying these fascinating fishes."--Bruce B. Collette, National Marine Fisheries Service Systematics Laboratory, National Museum of Natural History, Smithsonian Institution
