I apologize for the background noise. This video was filmed at the Reptile Discovery Center, in DeLand, Florida. Their website is below:

Just to clarify a few things (I know, trolls can't read, but I'm going to try anyways.)

Snakes have kinetic skulls this means their skulls are very complex, composed of several joints, hinges, and pieces, that allow them to expand and stretch in ways yours and mine simply can't.

This flexibility is an adaptation that enables snakes to swallow whole prey that are much larger than their heads.

So while it looks like the animals skull is getting smushed, that is not the case. It is simply flexing along it's natural joints.

also, people handling venomous snakes do not have the luxury of using a light and easy grip. Venomous animals are highly dangerous, and must be held securely at all times to prevent bites (and fatalities). A loose grip would enable the snake to bite him, or his assistants.
