Whale watching is one of the fastest-growing tourist activities in the world, attracting over four million people every year. This sumptuously illustrated book brings the exhilarating experience of whale watching to life for the whale and dolphin enthusiast. Whales, dolphins and porpoises are known collectively as cetaceans. "Whale Watcher" describes the world's species currently recognised with feature spreads on over 40 of the most frequently watched and fascinating species. For easy identification, families and species are described in descending order of size, from the blue whale to the tiniest dolphins and porpoises. Stunning action photography of each species is coupled with watching information, including guidance on where and when to watch, and how to identify the species from its behaviour and physical characteristics. The natural history and habitat of each animal is described, as well as the latest research on topics such as cetacean communication and social structure. There is also information on endangered species, responsible watching and conservation that make this an essential and comprehensive visual reference.
