Pigeons of the sea? Sharks use magnetic compass for navigation Researchers nail evidence that some shark species use magnetic forces as a natural GPS An overhead shot of bonnetheads in the holding tank. Credit: Bryan Keller Might be time to re-think your strategy for avoiding sharks: turns out the marine predators use the Earth’s magnetic field to navigate, according to new research from the US. The study has produced the first firm evidence that bonnethead sharks – a small type of hammerhead found in American waters – like birds and turtles, use magnetic fields to figure out where they...

Sharks use Earth's magnetic field as 'internal GPS' for migration "This means the sharks have the capability to remember a specific location and to navigate back to it." By (FtLaudGirl/iStock) Story at a glance A new study published in the journal Cell found that sharks use the Earth’s magnetic field for navigation. Scientists have long hypothesized this to be true, but this is the first study to support the theory. The findings explain how sharks are able to repeatedly revisit feeding grounds year after year after migrating thousands of miles. A new s...

Sharks can read Earth's field like a map and use it to navigate the open seas during long distance migrations, according to a new study. The Florida State University research found that sharks draw on magnetic fields to align themselves towards their preferred destination. "Even when they're far away, the animals know where they are and where to swim to get home," said study co-author Bryan Keller.

May 06, 2021 06:50 PM EDT Scientists have believed for a long time that these animals depend on magnetic sensing to travel across oceans. At last, someone puzzled out how to prove it. Great white sharks travel more than 12,000 miles yearly from South Africa to Australia, charting a closely ideal straight line across the ocean. And each year, they turn around and migrate back.

There is usually a change in currents an...

published : 7 May 2021 at 07:45 3 Research on bonnethead sharks has revealed that sharks can glean their position and orientation using the magnetic field generated deep within our planet. WASHINGTON: Forget Google Maps -- sharks can read the Earth's magnetic field like a GPS navigator to find their way, a study in Current Biology showed Thursday. Lead author Bryan Keller told AFP the paper vindicates a decades-old theory about how the aquatic predators are able to migrate vast distances, swim in arrow-straight lines, and return to their preci...
