This edited book brings out a comprehensive account of the faunal diversity in Great Nicobar Biosphere Reserve which is part of the Sundaland Biodiversity hotspot. The main focus of this volume is to address the ecological and economic significance of the biodiversity of this region. The book provides latest information on the faunal diversity of Great Nicobar Biosphere. It focuses on various faunal communities of this regions such as Floral diversity, Butterflies, Moths, Dragonflies & Damselflies, Termites, Hymenoptera, Coleoptera, Scorpion, Spiders, Turtle, Nicobar megapode. Chapters in this volume also covers Reptiles & Amphibians, Fishes, Mammals, Land and freshwater Mollusca. Marine animals such as Opisthobranchs, Sponges, Scleractinian Corals and Soft corals, Sea Anemones, Polyclads, Marine Molluscs, Echinoderms are also discussed. It is of interest for the researchers, teachers, scientists, capacity builders, policy makers. Also serve as reading materials for graduate and post graduate students e.g., Wildlife Biology, Forestry, Environmental Science, Wildlife Ecology, Zoology, Life sciences, Parks/Sanctuaries managers, National and International scientists, policy makers will also find this to be a useful document.

From the introduction: Cephalopods are the most highly organized molluscs and are the most accomplished swimmers other than fish. The size veries from minute to 55 m long and 2.5 m diameter. The class represented by 650 species belonging to nautilus, cuttlefish squids and Octopuses. There are 65 species under the class cephalopoda reported so far from the Indian Ocean region roper et al. 1984 of which 64 species are reported by ZSI. The collections present at the Zoological Survey of India is based on two primary sources viz. inherited from the Indian Museum and obtained from its own surveys conducted by the scientists and naturalists of the department.

With particular reference to India.

"Ponder and Lindberg provides a breathtaking overview of the evolutionary history of the Mollusca, effectively melding information from anatomy, ecology, genomics, and paleobiology to explore the depths of molluscan phylogeny. Its outstanding success is due to thoughtful planning, focused complementary contributions from 36 expert authors, and careful editing. This volume is a must for malacologists."—Bruce Runnegar, Department of Earth and Space Sciences, University of California, Los Angeles "Our understanding of the phylogeny and evolutionary history of the mollusca has been revolutionized over the past two decades through new molecular data and analysis, and reinvestigation of morphological characters. In this volume Ponder, Lindberg, and their colleagues do a wonderful job of integrating this work to provide new perspectives on the relationships of the major molluscan clades, their evolutionary dynamics, and their history. Particularly timely is the coverage of molluscan evo-devo and genomics."—Douglas H. Erwin, Curator of Paleozoic Invertebrates, National Museum of Natural History
