In a nutshell Scientists discovered sea turtles can learn and remember specific magnetic field signatures of geographic locations, effectively creating their own internal GPS system that helps them navigate back to important feeding grounds.

Researchers found loggerhead turtle hatchlings can be conditioned to recognize magnetic fields, which helps them locate feeding sites.

Loggerhead turtles “dance” when exposed to food-associated magnetic fields, and their magnetic map may help them return to specific areas after long migrations.

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.
