Why do sea turtles return to the beach where they hatched?
Quick Answer
Sea turtles use a powerful natal homing instinct, guided partly by Earth’s magnetic field and ocean cues. Females often nest near the same beaches where they were born.
The Full Story
Many sea turtles return to the region or even the beach where they hatched because of natal homing, a form of long-distance navigation. Scientists think they use a combination of the Earth’s magnetic field, wave patterns, currents, and coastal cues to find the right area. Female turtles usually come ashore to lay eggs on sandy beaches after spending years at sea. This behavior helps keep populations tied to suitable nesting habitat. It is also why beach conservation is so important for turtle survival.
