We would like to announce a Special Issue entitled "Threats to Cetacean Health", guest edited by myself and Dr. Leila Lemos. Please find submission instructions: https://www.mdpi.com/journal/animals/special_issues/F378F97U0S The uncontrolled growth of human population and anthropogenic activities along coasts and riverbanks has threatened aquatic ecosystems and their biota. Cetaceans, in particular, are at high risk of conservation, as they are especially sensitive to anthropogenic activities, including but not limited to negative interactions with watercraft and fishing gear, habitat destruction, pollution, noise, climate change, prey depletion, hunting, and diseases, acting as important ecosystem health indicators. Thus, this special issue aims to provide a comprehensive assessment of cetacean health worldwide and advance our understanding of the physiological mechanisms that control and regulate individual and population behaviors and dynamics, which can aid in effective and sustainable conservation actions. Review or original research articles on pollution levels and effects, physiological and behavior responses and body condition alterations caused by anthropogenic influences are especially encouraged.
