Antarctic seals may use the Earth's magnetic field to survive while hunting

The video discusses a research project on Weddell seals, focusing on their potential use of a magnetic sense for navigation. Researchers attach instruments to seals to study their behavior and test hypotheses about geomagnetic navigation. The video highlights the seals' remarkable adaptations, such as holding their breath for extended periods and swimming at high speeds. Challenges in tracking seals under ice are addressed with advanced instrumentation. The research involves experiments in different magnetic fields to observe behavioral changes, with plans for future studies to gather more data.
