9. Green Sea Turtle
Green sea turtles are renowned for their epic migrations between distant feeding grounds and the beaches where they nest. These ancient mariners navigate the open ocean with remarkable accuracy. Scientists have discovered that green sea turtles use the Earth’s magnetic signatures as a kind of biological map, while also taking advantage of prevailing ocean currents. This dual guidance system ensures they can travel thousands of miles and still return to the precise stretch of sand where their journey began. Source: National Park Service
