From NSF  --  Antarctica's Weddell seals have biological adaptations that allow them to dive deep--as much as of hundreds of meters--while hunting, but also an uncanny ability to find the breathing holes they need in the surface of the ice that covers the sea. Now, a team of researchers supported by the U.S. Antarctic Program, which is managed by the National Science Foundation, believe they have figured out they they navigate so well; by sensing the Earth's magnetic fields.
