Salmon’s Epic Magnetic Migration

Migrating Giants — The Secret Life of Salmon! "Every year, millions of salmon

undertake one of nature’s most extreme journeys. Born in freshwater rivers,

they migrate to the ocean, where they grow for years before returning to the

exact river of their birth to spawn. Scientists discovered that salmon use Earth’s magnetic

field like a natural GPS, memorizing its “magnetic signature” as juveniles. When it’s time to

return, they follow this invisible map across thousands of kilometers. Along the way,

they leap waterfalls, dodge predators, and even stop eating to conserve energy. This migration is

so precise that entire ecosystems depend on it — from bears and eagles to forests nourished
