Turtles have a remarkable ability called natal homing, which helps them find their way back to their birthplace to lay eggs. Scientists believe that turtles use a combination of cues such as Earth's magnetic field, ocean currents, smell, and visual landmarks to navigate back to their natal beaches. This incredible navigation ability is still not entirely understood, but it is believed to be a combination of instinct and memory that guides them back to the place where they were born.
