Evolution comes in handy. Researchers write that they have found one type of pitcher plant with a unique shape, designed to look attractive to bats using sonar to echolocate. Bats find their way around by emitting tiny noises that bounce off objects. When a bat's noise bounces off a certain part of the plant, called a reflector, it reflects back a loud, clear signal, telling the bat where to go (you can see the bat enter the plant in the gif above). The results are published in a new paper in Current Biology.
