There is a cool program available in the UK only titled Inside Nature’s Giants, which is meant to be taken literally — they actually record the dissection of megafauna. The first episode is about delving into the guts of an elephant.
The bad news is that it isn’t available outside Channel 4′s broadcast area, so I can’t watch it at home or here in Germany. You lucky Brits can tune in right now, though. Maybe it will make its way to youtube soon.
The good news is that it is also not available in Smell-O-Vision.
