In 2021, scientists tested 20 bonnethead sharks at Florida State and found they use Earth’s magnetic field to navigate: Study suggests sharks may have a magnetic map

Sharks possess an incredible ability to roam the expansive oceans, utilizing the Earth's magnetic field as their guide. Recent studies have shown that bonnethead sharks can detect these magnetic cues to navigate. This innate skill allows them to journey home across vast distances, potentially learned through their explorations. Gaining insight into their navigation methods is crucial for safeguarding their essential migratory paths.
