The Serengeti plain in East Africa is one of the world's most diverse and spectacular wildlife kingdoms. It's home to the bat-eared fox. They feed mainly on insects. With their long, big ears, they can detect the ultrasonic waves that insects emit. Ultrasonic waves usually travel in a straight line from their source, so a fox can determine the exact location the sound is coming from and strike, even if it's underground. During the rainy season, bat-eared foxes raise their young in underground dens. The parents work as a team to confront hyenas, honey badgers and other predators that single out their pups. Relying on their giant ears and tight bonds, bat-eared fox families survive in the Serengeti through their indomitable strength and will.
