Bats use water ripples to hunt frogs
January 23, 2014
As the male tungara frog serenades females from a pond, he creates watery ripples that make him easier to target by rivals and predators such as bats. He will stop calling if he sees a bat overhead, but ripples continue moving for several seconds after the call ceases. In the study, researchers found evidence that bats use echolocation to detect these ripples and hone in on a frog.
