How do turtles navigate across oceans?

Turtles navigate across oceans using a combination of environmental cues. They rely on Earth’s magnetic field, detecting its intensity and inclination to orient themselves. Visual cues, like the position of the Sun and stars, also aid navigation. Additionally, turtles use olfactory cues to identify specific regions or nesting beaches. This remarkable ability enables them to return to the same beaches where they were born, often after travelling thousands of kilometres.
