Whale shark sets amazing record for the longest migration ever - science news

Her name is Anne and she is a whale shark (Rhincodon typus) that marine biologists are following in the ocean. Using tagging technology, the scientist tracked the migration route of Anne, as she crossed the Pacific in what is now the world’s record for the longest migration of a whale shark. The distance of the migration reached the gigantic value of 20,142 km (12,500 miles)! The study is part of a long-term project in which 45 additional sharks around Panama are tagged and monitored. Interestingly, the reason for the migration of whale sharks is still a mystery for scientists!
