Magnetic fields linked to sea turtles' genetic profiles
4/13/2018

The genetic profile of a loggerhead sea turtle may be more closely linked to the magnetic fields where it hatches than the environment in which it lives, according to a study published in Current Biology. The turtles sense local magnetic fields to derive positional information and find their way back to nesting sites, but they can lose their way when structures have disrupted magnetic fields or when they sense an area with a similar geomagnetic signature.
