‘Secret GPS’: Sea turtles use magnetic superpower to surf vast oceans for treats, home
This new research provides the first concrete evidence that loggerhead turtles hone this remarkable ability. This superpower probably gui
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.
These sea turtles ‘dance’ when magnetic fields lead them to a snack
Loggerhead sea turtles ( Caretta caretta) are pretty loyal marine reptiles. Even with their roughly 8,000-mile-long migrations across oceans, they consistently return to the same feeding and nesting sites. Sea turtles can travel these distances by remembering the magnetic signatures of an area and storing that knowledge in a mental map.
'Dancing' turtles prove use of magnetic field as a map
The turtles danced with the most enthusiasm in the tank when they knew they would get food. This was "strong evidence" that turtles can learn the magnetic signatures of "specific geographical areas", the researchers said. Even when tested four months later, the turtles still knew where they should dance.
Sea turtles ‘dance’ in magnetic fields associated with food, new study finds
Loggerhead turtles “dance” when exposed to food-associated magnetic fields, and their magnetic map may help them return to specific areas after long migrations.
Researchers find out how baby sea turtles use magnetic fields to navigate
Researchers found loggerhead turtle hatchlings can be conditioned to recognize magnetic fields, which helps them locate feeding sites.
How sea turtles use Earth’s magnetic field as a GPS for precise ocean journeys
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.
