These Islands are often referred to as IIZoologists' Paradise" because of their unique faunal wealth that has been the subject matter of active investigation since the middle of the 19th Century. But very little has been explored so far and informa tion in this regard is almost lacking. It is in this context that Dr. B. K. Tikader, Director, Zoological Survey of India, who is also the author of the books "Threatened Animals of India" and IIBirds of Andaman and Nicobar Islands" has written this book covering all the major faunal groups available in these Islands. Dr. A. K. Das, the co author of this book, is also a noted Zoologist and had been the Officer-in-Charge of the Andaman and Nicobar Regional Station of the Zoological Survey of India for six years. The Zoological Survey of India is doing a commendable job in the exploration and study of the faunal wealth of these Islands. For taking up such activities, a full fledged Regional Station was established at Port Blair in the year 1977. Dr. Tikader, Director of this Institution, is a dedicated worker and has been taking lot of interest in the development of the faunal wealth of the Islands. His love and devotion for the fauna of these Islands have compelled him to write a large number of research papers and the book on the Andaman birds has been appreciated by the bird-watchers of these Islands. The present book "Glimpses of Animal Life of Andaman & Nicobar Islands" gives a detailed faunal account of these Islands, which was a long felt need. It is, therefore, heartening to note that authors like Dr. Tikader and Dr. A. K. Das who have been associated with these Islands for a long time have dealt with the subject in a lucid manner. I am sure that this publication will be welcomed by all concerned and will be of great interest and use for the tourists, the general public and the students of Zoology. (M L KAMPANI) Port Blair Lieutenant Governor A & N Islands v EDITOR'S PREFACE The Andaman and Nicobar Islands, comprising 324 large and small islands and covering an area of 8,300 sq.km. are unique in their variety of fauna and flora. The isolation of these islands from the mainland has been responsible for the high degree of endemism and as many as 32 species and subspecies of mammals, 95 species and subspecies of birds, 23 species and subspecies of reptiles are endemic in these islands. With regard to the flora and fauna, a large number of species are common between these islands and the Indian mainland besides Burma & Malaysia. The book "Glimpses of Animal Life of Andaman & Nicobar Islands" gives whatever information is available in this regard. It clearly indicates the diversity, richness and uniqueness of the faunal wealth of these islands. In this context, the authors have attempted to bring out this publication covering an overall faunal life of these islands. The book covers information on mammals, birds, reptiles and amphibians. As for fishes, although the marine fish fauna of these islands is extremely rich and varied, only the commercially important marine fishes and also some freshwater, estuarine and stream fishes are dicussed. The sea-shore animals which are very attractive particularly to the tourists are dealt with in general. A separate book "Sea-shore Animals of Andaman and Nicobar Islands" is under publication where all in formation in this regard has been furnished. The tribal people of these islands and their social life are also discussed in brief. Further, some general information regarding these islands is also appended to this book for the convenience of tourists. Moreover, the colour photographs of many animals as well as important monuments like the Cellular Jail and different types of forests are given. Dr. Asok Kumar Das, co-author of this book has been engaged for many years in studying fauna of these islands. During the course of his career in the Zoological Survey of India, he was posted at Port Blair and availed the opportunity of surveying fauna of these islands. It is my privilege that I am able to write the preface of this popular book by virtue of my position as Editor and to this particular one of which I am the senior author. It is hoped that this illustrated book will serve as an important and informative document on these fascinating islands, mainly for tourists, students and naturalists in India and abroad.
