Udo Groger, a biologist at Ludwig-Maximilians University in Munich, Germany, discovered that vampire bats, Desmodus rotundus, can memorize and recognize the sound of an individual's breathing. Like a voice, every individual has a unique breathing pattern. The bats can follow this sound to its source.
That can be a lifesaving trick. Vampire bats feed on prey, such as livestock, that are 1,000 times their size. "Biting [the] animal is a big risk," says Groger. If a bat finds an animal that doesn't wake while the bat feeds, the night flier benefits by returning to the heavy sleeper several nights in a row.
