Some animals that migrate across the globe-such as birds, salmon, lobsters and sea turtles-are known to navigate using the magnetic field lines that stretch from Earth's north to south pole

Sea turtles are capable of creating GPS-like magnetic maps to guide them back to foraging grounds, and they do a little dance when they recognize those spots

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.

Loggerhead sea turtles do an excited "turtle dance" when anticipating food. It's adorable, of course, but it has also allowed scientists to understand better how the turtles navigate. Scientists have theorized that sea turtles memorize coordinates to navigate using a magnetic "map.

Dancing turtles have proved for the first time that some animals use Earth's magnetic field to create a personal map of their favorite spots, scientists said Wednesday.
