Just for fun, I uploaded a few videos of some work I did at Manchster University where we put dead bats into a micro CAT scanner. Taking the 4000 or so x-ray images of the bat as it rotated in the chamber I stitched them together into a film. I hasten to add that the bats had all died from natural causes and had been in my freezer for years. In the first one, of a Daubenton's bat, you can see nice details of the skull, teeth, Cochlea and shoulder.

The second is of a long eared bat, you can see the ears as light shadows. Again, nice detail in the cochlea.
