11. Humpback Whale
Humpback whales are the marathon swimmers of the ocean, traveling up to 16,000 miles annually between feeding and breeding grounds. Scientists believe these giants use a combination of Earth’s magnetic fields, subtle changes in water temperature, and even the sun’s angle to guide their impressive migrations. Their ability to traverse such vast and sometimes featureless oceans showcases a navigational prowess that still puzzles researchers today. Source: MarineBio Conservation Society
