We are awed by the power and mystery of whales. The chance to glimpse one is the reason people flock to the east coast to enjoy some of the world's best whale watching. This guide to 39 species of whales, dolphins, porpoises, seals and otters opens a window on the behaviour of these complex and social creatures. The book features colour illustrations and photos throughout, detailed physical descriptions, range maps, information on group sizes, feeding habits, conservation status, reproduction and more. Colour-coded header bars and a quick reference guide make information fast and easy to find.
