I think that it is a misconception that since they are called rear fanged that the food must go all the way to the back of the mouth in order to be envenomated. The "fangs" are actually located underneath the eyes which is only halfway down an open mouth. From what I've seen from Hognose feeding behavior (swinging their open mouth wildly) that it is not hard to get the fangs latched on if they get any grip at all.

>>Since hogs are rear-fanged...that the only way a hognose is going to get any significant amount of venom into a toad is by getting one hell of a good bite and chewing on it...in which case...it ain't gettin' away.

>>If it bites and isn't able to hold on and chew...likely the toad isn't going to receive any venom and will live another day to hop out in front of a car or something.
