Australia's isolation from the rest of the world has led to the evolution of many unique species of mammals. This book introduces all of the major groups including egg-laying mammals, pouched mammals, placental mammals, introduced mammals and marine mammals. There is emphasis on those species the amateur naturalist and nature-lover is most likely to see. Information is organized simply, with individual species or group entries describing key characteristics such as where they are found, food requirements and behavioural habits. Each entry is accompanied by a photograph and, where appropriate, distribution maps. A key feature of the text is the "gee whiz" sections, which answer many of the most commonly asked questions about why animals do what they do, revealing interesting facts and providing practical information for the amateur enthusiast. In addition, fact panels interspersed throughout the text highlight surprising snippets of information.
