For those interested in anatomy, you may want to check out Inside Nature's Giants on PBS (check you local listings)

They do field dissections of huge species that have died of natural causes.

You get to see them dissect and manipulate a sperm whale, python, great white shark, tiger, and lion.

The Sperm whale and python episodes are currently available on the website. Shark, tiger, and lion should be up later.
