So the snake was moving along the ground and got "hit" by the electric fence and then struck at it killing it?<br /><br />Interesting. What kind of snake is it? Some kind of boa?
Actually, they do bite to hold onto their prey until they can wrap around them and constrict them. That's why the teeth are angled backwards-to hold on to the prey.
Not sure on the folding, Les, but I don't believe they do. I know snakes have died trying to consume something too large, mostly because they could not spit it back out. I imagine because of the teeth.
