摘要：SummaryAdvances in biologging technology have enabled 3D dead-reckoning reconstruction of marine animal movements at spatiotemporal scales of meters and seconds. Examining high-resolution 3D movements of sharks (Galeocerdo cuvier, N = 4;Rhincodon typus, N = 1), sea turtles (Chelonia mydas, N = 3), penguins (Aptenodytes patagonicus, N = 6), and marine mammals (Arctocephalus gazella, N = 4;Ziphius cavirostris, N = 1), we report the discovery of circling events where animals consecutively circled more than twice at relatively constant angular speeds. Similar circling behaviors were observed across a wide variety of marine megafauna, suggesting these behaviors might serve several similar purposes across taxa including foraging, social interactions, and navigation.Graphical abstractDisplay OmittedHighlights•Biologging 3D movement data revealed circling behaviors in marine animals•Circling behaviors were observed in sharks, turtles, penguins, and marine mammals•Circlings might serve several purposes including foraging, navigation, etc.Ecology; Biological Sciences; Zoology; Animals; Ethology
