Sea turtles' secret GPS: How loggerheads learn locations using Earth's magnetic field

A new study from researchers at the University of North Carolina at Chapel Hill provides the first empirical evidence that loggerhead sea turtles can learn and remember the unique magnetic signatures of different geographic regions. This discovery offers new insights into how turtles and other migratory animals navigate vast distances to reach specific foraging and breeding grounds. The findings, published in the journal Nature, also suggest that sea turtles possess two distinct magnetic senses that function differently to detect the Earth's magnetic field.
