Dear MarMam Community, My colleagues and I are pleased to announce the publication of our study, "Paradoxical escape responses by narwhals (Monodon monoceros)" by Terrie M. Williams, Susanna B. Blackwell, Beau Richter, Mikkel-Holger S. Sinding, and Mads Peter Heide-Jørgensen in Science 358: 1328-1331, 2017. This study addresses the question, how do marine mammals "run away" from a threat while holding their breath? Using a custom-built ecg-accelerometer-depth meter developed with aquaria dolphins, we reveal a paradoxical escape response in wild narwhals that challenges their physiology. This finding has far reaching implications, and may provide insights about the physiology of cetacean strandings, the underlying mechanisms of capture myopathies, and the potential for injury in deep-diving cetaceans due to unanticipated threats including oceanic noise. Information about the pdf is available from T.M. Williams. Best Regards, Terrie
