This book is the culmination of almost twenty years' study of one of the world's most intelligent creatures. Dr Dobbs, a scientist by training, shows how dolphins can help to banish stress, and he also suggests a new approach to one of the world's gravest environmental problems. He tells the story of the wild dolphin Freddie, which haunts the Northumbrian coast near Amble, of JoJo's almost telepathic response to humans in the Caribbean, of the dolphins of Monkey Mia in Australia and their affinity with much in aborigine culture - and an extraordinary encounter with humpback whales the size of submarines.
