How do sea turtles navigate across the oceans?

Sea turtles navigate across the oceans using a combination of magnetic fields and visual cues. They are capable of detecting the Earth’s magnetic field, which helps them navigate thousands of miles between their feeding grounds and nesting sites. Sea turtles imprint on the magnetic fields near their birthplace, enabling them to return to the same area decades later to breed. They also use the Sun and stars for navigation, especially during migration, and may rely on coastal landmarks for guidance when closer to shore.
