For bats, darkness isn’t an obstacle—it’s their playground. Using echolocation, these night flyers emit high-frequency calls that bounce off objects, painting a sonic map of their surroundings. This ability allows them to hunt insects mid-air with the kind of precision that would make any fighter pilot jealous. Dolphins use a similar technique underwater, navigating murky depths and tracking prey with clicks and whistles. Beyond hunting, sound plays a major role in animal communication, whether it’s birds singing to attract mates or whales exchanging calls across vast ocean distances.
