Marine mammals (MMs) are regarded as valuable bioindicators with tremendous potential for public health. However, many aspects of their immune system remain poorly understood. Monitoring immune responses of MMs is pivotal for the health assessment of both individuals and populations, as well as providing the scientific basis for analyzing the anthropogenic environmental impact on marine ecosystems and marine-terrestrial interphases. For instance, the increasing susceptibility of Mediterranean whale and dolphin populations to various diseases has been linked to a possible negative influence of multiple environmental factors on the immune system of MMs. The currently limited knowledge on MM immunology has mainly centered on: (i) lymphocyte transformation assays; (ii) natural killer cell activity; (iii) phagocytic activity and respiratory burst; (iv) humoral immune responses; (v) cytokines and (vi) acute phase immune responses. Therefore, further research is essential for deepening our understanding of the specificity of the host immune response in MMs, with a particular emphasis on the genesis and dynamics of (i) cytokine ‘networks’ or ‘signatures’; (ii) transcriptional regulation of immune cells and (iii) major immunomodulators. High-throughput molecular techniques, such as transcriptomic analysis and RNA sequencing, may enable the characterization of immune gene responses at the transcriptomic level. This integrative and holistic approach requires sophisticated tools and methods capable of unveiling the diversity of immune cells and immunologically relevant molecules that orchestrate environmental adaptation and immune protection against pathogens in MMs. This Research Topic aims to provide a comprehensive overview of the current knowledge of MM immunology with a particular emphasis on structural and functional studies at the protein and cellular level. We wish to encourage and coordinate studies and investigations in order to fill gaps of knowledge in this field. This article collection aims to help gain more data regarding: a) The characterization of the immune system in several species of MMs, i.e. cetaceans, pinnipeds and sirenians; b) The interplay between the host immune system and the most relevant pathogens, e.g., Morbillivirus, Brucella, Toxoplasma gondii and c) The possible interplay between the immune system and contaminants.

AAP Prose Award Finalist 2018/19 For three decades, this book has been acknowledged as the most respected scientific reference specifically devoted to marine mammal medicine and health. Written by approximately 100 contributors who are recognized globally as leaders in their respective fields, the CRC Handbook of Marine Mammal Medicine, Third Edition continues to serve as the essential guide for all practitioners involved with marine mammals including veterinarians, technicians, biological researchers, students, managers, keepers, curators, and trainers. The 45 chapters provide essential information for the practitioner on pathology, infectious diseases, medical treatment, anesthesia, surgery, husbandry, health assessment, species-specific medicine, medically pertinent anatomy and physiology, and global health concerns such as strandings, oil spills, and entanglements of marine mammals. Covers all aspects of marine mammal veterinary practice Written by internationally acknowledged experts Adds new chapters on Ophthalmology, Dentistry, Ethics, Oil Spill Response, Health Assessments, Whale Entanglement Response, Dive Response, and Biotoxins Richly illustrated in color throughout the new edition including updated anatomical drawings and extensive photographs of ocular lesions Provides guidance to websites that regularly present updated information and images pertinent to current marine mammal medicine such as imaging and stranding network contacts Discusses ethics and animal welfare. The book guides the reader through the veterinary care of cetaceans, pinnipeds, manatees, sea otters, and polar bears. In addition to summaries of current knowledge, chapters provide information on those digital resources and websites which present the latest information as it emerges in the field. The CRC Handbook of Marine Mammal Medicine, Third Edition gives a call to action for scientists to experiment with new endeavors to engage and inspire current and future generations to care for marine mammals and the marine environment, and work together to find solutions. As the most trusted reference for marine mammal conservation medicine and for marine mammal medical facilities around the world, this book needs to be in your library.

Marine Mammal Ecotoxicology: Impacts of Multiple Stressors on Population Health provides tactics on how to develop a comprehensive methodology for the study of existing threats to marine mammals. By presenting a conservation-biology approach and new and emerging technologies, this work helps provide crucial knowledge on the status of marine mammal populations that not only helps readers understand the ecosystem's health, but also instigate mitigation measures. This volume provides information that helps investigators unravel the relationships between exposure to environmental stressors (e.g., climate change, pollutants, marine litter, pathogens and biotoxins) and a range of endpoints in marine mammal species. The application of robust examination procedures and biochemical, immunological, and molecular techniques, combined with pathological examination and feeding ecology, has led to the development of health assessment methods at the individual and population levels in wild marine mammals. - Provides a comprehensive, worldwide update and state of knowledge on current research and topics on marine mammal ecotoxicology - Includes coverage of both new and emerging technologies - Features a multidisciplinary approach that gives readers a broad, updated overview of the threats facing marine mammals and related conservation measures

Suppose you were designing a marine mammal. What would you need to think about to allow it to live in the ocean? How would you keep it warm? What would you design to allow it to dive for very long periods to extreme depths? Where would it find water to drink? How would you minimize the cost of swimming, and how would it find its prey in the deep an

The activities of modern society have unleashed a range of toxic chemicals into the global environment. Many of these toxicants are now being detected in increasing quantities in the tissues of marine mammals, most notably in top predators who acquire relatively large amounts of toxic chemicals by ingesting contaminated prey. Toxicology of M

Marine mammal conservation presents a number of challenges for scientists. This work presents an argument about how science, if conducted properly, can provide insights needed to minimise crisis management and implement more anticipatory action.
