Salmon Use The Earth’s Magnetic Field To Navigate Thousands Of Miles
Salmon are known for their health benefits when they end up on someone’s dinner plate, but these incredible fish should also be recognized for their super navigation skills. Salmon eggs hatch in freshwater, and when the fish are big enough, they swim up to 2000 miles to the open sea.
When the time comes for them to lay eggs, they go back upstream – sometimes thousands of miles – to spawn in the same place where they were originally hatched. They are attuned to the Earth’s magnetic field and follow their patterns to return to their original home.
