How do sea turtles navigate across the ocean?

Sea turtles navigate across vast ocean distances using a combination of environmental cues and magnetic fields. They are thought to use the Earth’s magnetic field to determine their location and direction. Turtles are also capable of detecting the Earth’s geomagnetic variations, which help them navigate specific routes during their long migrations. They can return to the same beaches where they were born to lay eggs, a remarkable feat of navigation that involves both innate instincts and environmental memory.
