The book introduces various mammalian species to non-zoologists through line drawings and by providing brief description of their external appearance, colour, size, distribution, habits and behaviour. The book also fills in the need-felt gap in the requirement of reading material on nature, the biodiversity and the animals living around man. It is hoped that by going through the mammals of the Thar desert, the children would be able to conceive the idea of environment protection, conservation of the ecological systems and will inculcate love and admiration for the wildlife and nature.
