Seems like every day I learn something new and fascinating about these guys. I just love learning about all their adaptations. For such a simple looking animal, they are remarkably complex and capable. ^_^ The most recent interesting fact that I came across is that they can hear and smell in stereo, due to the forked tongue and their jaw being comprised of two separate parts. Apparently they now believe that snakes use their jaw bones in conjunction with their inner ear in order to sense sound waves in much the same way a ship would tranlslate waves of water. This is one reason they so often rest and slither with their jaw in contact with the ground. They still believe they are deaf to airborne sound (the vibration doesn't carry well) but their ability to sense transmission of vibration through the ground is extremely good.
