The regularity of dive performance in sea turtles: a new perspective from precise activity data

► We investigate diving performance of hawksbill turtles using multisensor data logger. ► Dive duration of hawksbills is regulated by the activity level and the lung air volume. ► Hawksbills rarely perform anaerobic dives. ► The diving strategy of hawksbill turtles maximizes their time spent submerged.
