1. Sockeye Salmon

Found in the Northern Pacific Ocean and rivers discharging into it, the Sockeye Salmon is known for its ability to sense the Earth’s magnetic field to guide it home. Scientists have discovered that the fish can imprint on the magnetic field that exists where they first enter the sea as juveniles, and, when they reach maturity, they seek the coastal location with the same magnetic field. This allows them to navigate more than 4,000 km (2,500 mi) to spawn in the same stream in which they hatched.
