It is apparent from this video that I ought have credited at least the photo of the side on view of the teeth to Matt's wife, Kat. Now edited that change into the original Post.
The droll commentary is mostly my own work (you can hear Matt and Kat's voices as well).
On occasions the comments were inspired by the biting by the Antechinus. It did not hurt, just surprised me by its speed and enthusiasm for chewing on my finger. As I said in the Blog originally, they "have attitude".
Warning: Mild coarse language on the Video.
