One of the great marvels of nature is how animals behave – how they live and reproduce, how they hunt and feed, how they survive. They make a living in hundreds of different ways, some of them quite extraordinary. Scientists who are interested in how animals live spend their lifetime studying their behaviour. They watch them in the wild, in jungles, deserts, on snow and ice, up in the mountains or down in the oceans. The more they learn, the more they are impressed by the tricks animals use to survive in an unfriendly world. This book is about what animals do to keep themselves alive, to live as comfortably and efficiently as possible, and to perpetuate their species. It tells of a wide range of animals, mostly birds and mammals, but some insects, reptiles, fish, amphibians, and others too. Some are familiar, everyday kinds of animals, others are strange and exotic creatures that you would be lucky to see even in zoos. This book is a family book for anyone interested in animals and their ways.
