Still Waters Posted May 7, 2021 #1 Share Posted May 7, 2021 Sea turtles are known for relying on magnetic signatures to find their way across thousands of miles to the very beaches where they hatched. Now, researchers reporting in the journal Current Biology on May 6 have some of the first solid evidence that sharks also rely on magnetic fields for their long-distance forays across the sea. Researchers had known that some species of sharks travel over long distances to reach very specific locations year after year. They also knew that sharks are sensitive to electromagnetic fields. As a result, scientists had long speculated that sharks were using magnetic fields to navigate. But the challenge was finding a way to test this in sharks. https://phys.org/news/2021-05-sharks-earth-magnetic-fields.html Map-like use of Earth’s magnetic field in sharks. https://www.cell.com/current-biology/fulltext/S0960-9822(21)00476-0? 1 1 Link to comment Share on other sites More sharing options...
lightly Posted May 7, 2021 #2 Share Posted May 7, 2021 Birds too huh ? I'd bet all sorts of migrating animals utilize the magnetic field to navigate? How about huge herds of caribou ? Link to comment Share on other sites More sharing options...
