This stunning slow motion footage shows how bats use echolocation to find water. We know how bats echolocate to hunt insects, but this is the first study to show how they recognise large, flat objects like ponds. Moreover, by testing young bats that had never encountered a pond or river before, the researchers showed that bats seem to have a built-in ability to recognise these important features of their environment.
