Sea turtles navigate oceans using Earth's magnetic fields
Sea turtles use Earth's magnetic fields as a natural GPS, navigating thousands of miles across oceans to find feeding grounds and nesting sites, a truly ancient and remarkable ability.
Sea turtles possess an incredible internal compass, using Earth's magnetic fields to navigate vast oceans. This phenomenon, called magnetoreception, allows them to sense variations in the planet's geomagnetic field, determining their latitude and longitude. For instance, loggerhead hatchlings instinctively swim towards the open ocean by orienting themselves with these magnetic cues.
