Sharks use Earth’s magnetic field as their own GPS Updated 7:35 AM; Today 7:35 AM In this Sept. 2015 photo taken by Colby Griffiths on the North Edisto River in South Carolina, scientist Bryan Keller holds a bonnethead shark. Keller is among a group of scientists that found sharks use the Earth’s magnetic field as a sort of natural GPS when they navigate journeys that take them thousands of miles across the world’s oceans.

May 13, 2021 Longstanding mystery solved! New research shows that – just as lobsters, turtles and some birds do – sharks navigate using Earth’s magnetic field, Sea turtles, lobsters and some birds rely on Earth’s magnetic field to navigate to the beach of their birth or their winter getaway during migration. On May 7, 2021, researchers reported the first evidence that sharks, which are more difficult to study, are included in the group of animals that have a magnetic sense, making it possible to map their surroundings and to maintain their heading while navigating long distances, usi...

Want to confuse a shark? Use a magnet Salon 5/12/2021 Shark GPS Illustration by Salon/Getty Images Sharks are renowned for their razor-like teeth and keen sense of smell, which allows them to sniff out blood from far away. And while these well-adapted traits have enabled them to roam Earth's seas for around 400 million years, the fearsome predators are not exactly known for being expert navigators akin to migratory species like birds. Yet sharks' reputation as navigators is about to change, as a new study finds that sharks appear to have a compass built...

WASHINGTON (AFP) – 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 recently. 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 […]
