Whales, birds, and ladybugs are known for traveling thousands of miles for migration. But the researchers have recently found a terrestrial mammal who travels farthest for migration. Caribou has been rewarded with the world’s longest migration mammal. Researchers have even double-checked the stats to see if another animal is coming on the top spot. The runners-up among the list are reindeer from the Taimyr Peninsula in Russia, which traveled nearly 750 miles per year. Although, researchers have praised the study, they are now seeking more accurate statistics of the migrators’ routes.
