by Migration is common in marine animals and use of the map-like information of Earth’s magnetic field appears to play an important role.
While sharks are iconic migrants and well known for their sensitivity to electromagnetic fields, whether this ability is used for navigation was unresolved.
“Our research supports the theory that they use the Earth’s magnetic field to help them find their way.
It’s nature’s GPS,” said study’s lead author Dr. Bryan Keller, a researcher in the Florida State University Coastal and Marine Laboratory.
“Bonnetheads return to the same estuaries each year.
This demonstrates that the sharks knows where ‘home’ is and can navigate back to it from a distant location,” he added.
