Sea turtles use magnetic maps to navigate oceans - February 25, 2011
 
Loggerhead turtles can do from birth what humans struggled to master for centuries – tell longitudinal, or east-west, direction to navigate thousands of miles of ocean with no visual landmarks. They do so using magnetic cues, according to a study by researchers from the University of Florida published in the journal Current Science.
The turtles set off on a grand migration around the Atlantic immediately after they hatch and enter the sea. They swim from Florida to the circular currents swirling around the Sargasso Sea, called the North Atlantic subtropical gyre. They stay in the gyre and slowly migrate around the Atlantic, before returning home.
