What fish species migrates upriver in huge numbers to lay eggs, creating a major event for predators?

Did you know that one of the most extraordinary animal migrations on the planet is the journey of the Arctic tern?
These remarkable birds travel a mind-boggling distance of about 30,000 kilometers each year.
They migrate from their breeding grounds in the Arctic to the Antarctic and back again, experiencing two summers annually in the process.
This incredible round trip is not only the longest migration of any animal but also allows the Arctic tern to enjoy more daylight than any other creature on Earth.
Their path, guided by instinct and environmental cues, showcases the marvels of nature’s navigation systems, proving that even the smallest creatures can achieve extraordinary feats.
