Elephants communicate using very low-frequency sounds called infrasound, which can travel several kilometers through the ground. Sensitive receptors in their feet and trunks allow them to detect these vibrations.
This helps elephant herds stay in contact even when they are far apart or cannot see each other. Scientists believe they use this ability to coordinate movement, locate mates, and warn of danger. It's an amazing example of communication beyond the range of human hearing.
