Video Made by Dr. Chang Shown on Animal Planet

On July 17, 2011, Animal Planet aired Swamp Wars "Snake Farm Shootout" where a video made by Dr. Chang was incorporated into the storyline. It was a VERY brief segment of this video clip shown about 30 minutes into the show; specifically, the endoscopic image of the back of the nose. Due to copyright, I can't show the actual video clip. But, here is the video from which the segment was taken.
