Synopsis Zoology is the study of life in its entirety. The growth of Zoology as a natural science during the last 1000 years is interesting from many points of view. One feature of this growth is changing emphasis. Initially, it was description of life forms. Identification, nomenclature, classification of all recorded living forms, enjoyed the attention of scientists for a long time. Description of habitats of animals and their behaviour was included in this study. Zoology is concerned with the study of animals and their living conditions. This book includes the Problems and Solutions of Zoology in a more detailed and descriptive way. This book would make the readers experience the humbling effect of this realisation that all organisms are related to each other virtue of sharing genetic material. We hope that this book would help the students to become more familiar with the diversity of animals. We are indebted to the various authorities on the subject. We gratefully acknowledge them. Last but not the least my publishers who appreciated this book and brought this work in a record time.
