Decapod crustaceans, shrimps, crabs, prawns and their allies are highly visible and important members of marine environments. They are among the most charismatic of marine animals, inhabiting beaches, rocky shores and the deep sea, hiding under stones, burrowing in the sediment and nestling in among algae and many other microhabitats. However, most are difficult to identify by the specialist and amateur naturalist alike. Marine Decapod Crustacea explains the anatomical features necessary for differentiating taxa and includes diagnoses and identification keys to all 189 families and 2121 genera of marine Decapoda. Many decapods have vivid colours, which are showcased in a selection of spectacular photographs of many representative species. This volume provides an entry to the literature for taxonomists, naturalists, consultants, ecologists, teachers and students wanting to identify local faunas and understand this diverse group

The book provides information on the sources of arsenic contamination of groundwater and their impacts in the first part of the book consisting of 8 chapters. Process developments such as nano-adsorbents for removal of arsenic and other heavy metals are discussed in the second part of the book that comprises of 4 chapters. The third part of the book includes 4 chapters on technological interventions for the removal of arsenic such as indigenous ceramic membranes and Subterranean Arsenic Removal (SAR). The fourth part of the book deals with arsenic contamination in food materials and food chain systems, and consists of 5 chapters. Arsenic has long been associated with a variety of health complications in the human body. In order to address this, a chapter on arsenic contamination and impacts on human health has been included in the fifth part of the book. The book would be a valuable reference material for the scientific community in developing countries working on community water supply and treatment, food safety, public health and policy.
