Why do sea turtles return to the same beach to lay their eggs?

Sea turtles return to the same beach where they were born to lay their eggs, a phenomenon known as natal homing. This behavior is thought to be guided by the Earth’s magnetic field, which allows turtles to imprint on the unique magnetic signature of the area. As adults, they use this “magnetic map” to navigate across vast distances of ocean to return to their birthplace. This instinct ensures that the next generation of turtles hatches in the same safe, familiar environment, enhancing their chances of survival.
