With the sustained increase in anthropogenic factors impacting wild cetaceans, determining strategies to help to conserve populations while monitoring their health and welfare is critical. Similarly, it is also essential to continuously look for new ways to enhance the health and welfare of cetaceans under professional care. The Special Issue is dedicated to research on cetaceans both in the wild and under professional care that advances our understanding of their conservation, health, and welfare. Examples of potential submissions include: * Studies of population abundance, distribution, and behavior; * Impact of anthropogenic factors and conservation management strategies; * Statistical, technological, and methodological advancements; * Validation and reference values for positive and negative indicators of health and welfare; * Factors impacting health and welfare; * Conservation education research and visitor studies; * Review articles on conservation, health, or welfare.
