Nothing quite matches the thrill of witnessing a pod of these immense creatures cutting through the waters of Johnstone Strait or listening to their strident underwater calls to each other in their own dialect.\nThis new edition of this best-selling book presents updated results of over twenty-five years of killer whale research in British Columbia and Washington. Intended for both whale enthusiasts and researchers, it contains the latest information on killer whale natural history and presents a catalogue of close to 300 photographs of \"resident\" killer whales as well as a genealogical registry that enables readers to identify individual killer whales and their family groups. The technique of photographing the dorsal fin and grey saddle patch of whales has revolutionized the study of killer whales, allowing researchers to follow individuals over the course of many years.\nAlso new in this edition is the latest information on the status and future prospects of west coast killer whales -- how they may be affected by declining salmon stocks, high levels of toxic chemicals in their tissue, and increasing vessel traffic and underwater noise. Whale watchers will particularly appreciate revised suggestions and guidelines on how to view whales in the wild without disturbing them.\u003cbr\u003eASIN: 0774808004\u003cbr\u003eVSKU: BVV.0774808004.G\u003cbr\u003eCondition: Good\u003cbr\u003eAuthor\/Artist:Kenneth C.
