5. Sockeye Salmon
Sockeye salmon are celebrated for their extraordinary homing instinct. After spending years in the open ocean, they return to the exact rivers and streams where they were born to spawn. Their navigation toolkit includes detecting chemical cues in the water, following the sun’s position, and possibly sensing the Earth’s magnetic field. This natural guidance system ensures that each generation finds its way home, continuing the cycle of life. Source: U.S. Fish & Wildlife Service
