Whose discovery showed that sea turtles navigate using Earth’s magnetic field?
Quick Answer
Scientists including Kenneth and Catherine Lohmann demonstrated in the 1990s and 2000s that sea turtles use magnetic cues for navigation. Their experiments showed that hatchlings can detect magnetic signatures linked to ocean locations.
The Full Story
Kenneth and Catherine Lohmann were central figures in proving that sea turtles use Earth’s magnetic field as a navigational map. Their experiments with hatchlings and juveniles showed that turtles respond to magnetic inclination and intensity, which helps them orient across vast ocean distances. This finding explained how turtles return to feeding and nesting grounds after long migrations. It also became one of the strongest examples of magnetoreception in marine animals.
