The great growth of information about animals, zoology has been much subdivided. Some major fields are anatomy, which deals with gross and microscopic structure; physiology, with living processes in animals; embryology, with development of new individuals; genetics, with heredity and variation; parasitology, with animals living in or on others; natural history, with life and behavior in nature; ecology, with the relation of animals to their environments; evolution, with the origin and differentiation of animal life; and taxonomy, with the classification of animals. The information in this book makes it clear that successful zoologists do not come from any particular race, gender or social standing. They are a diverse group, but what they do have in common is curiosity and willingness to work hard to have their questions answered. This encyclopaedia is covering almost four hundred zoologists from around the world arranged in alphabetical order. This encyclopaedia is also covering Indian Zoologists. This encyclopaedia is beneficial for researchers, Zoologists, scientists, students and for all those associated with the subject.
