I'm working on a "theory" and I've been meaning to ask this for a while.

Is anyone familiar with any species of snake, other than A. piscivorous, that regularly tilts it's head back when gaping as a defensive display so that the mouth is opened upward?

I know lots of species that gape but all the others I know usually face forward. And I AM interested in hearing from anyone keeping cantils.

Yawning, stretching or respiratory infections don't count.

I've seen dusky pigmys exhibit this behavior.

I have seen Western pigs (streckeri) do the same thing also, albeit very quickly, like a flash. (While in a coil, perhaps they were startled)

Jumping vipers....although the will usually not hold it open as long as cottonmouths.
