How do they KNOW that it feels the residual heat left from the mouses feet and also that it uses its jaw bone to pick up the sounds?I would not think a mouse running off would leave a heat trail.IDK,alot of stuff in these shows just seem like theory to me.http://www.youtube.com/watch?v=6QKBG146dsI&feature=SeriesPlayList&p=A4DCD96B62760E82

Scientists dissect the snake and are able to determine how many heat receptors there are by using a microscope and then they track how sensitive they are to heat by measuring the electrical impulses produced when they are exposed to various temperatures.

I had a similar question and this is what the department head of Herpetology at the University of FL told me.
