This is Scientific Americans' 60-Second Science. I am Karen Hopkin, this will just take a minute.
Most school kids know that snakes can see with their noses, Vipers 1 in particular have these organs on their noggins that allow them to see heat which helps them find their warm blooded prey 2. If that's not wild enough for you, now physicists 3 from Germany and Kansas say that snakes can hear with their jaws 5. An idea they present in an upcoming issue of Physical Review Letters. See, snakes don't have actual ears, at least not on the outside, but they do have fully-formed inner-ear systems, complete with a cochlea, the fluid filled bone that harvests sound. But in snakes, the cochlea is connected to the jaw 4 bone. So if you walk past a snake that's resting with its head on the ground, the vibrations 6 from your footsteps jiggle the snake's jaw which shakes the snake's cochlea, so the snake can hear you move. In fact, the physicists found that this whole listening with your mouth setup can sense even the tiny vibrations made by scampering 7 rodents 8 or other small prey. And because snakes can unhinge their jaws one side at a time, they may be able to hear in stereo, which means that tapping on the glass of the rattlesnake exhibit is actually twice annoying as anyone ever realized.
Thanks for the minute, for Scientific Americans' 60-Second Science. I am Karen Hopkin.
