Not so much rear fanged. Boomslangs fangs move also. They also have very very large fangs. i would say larger then some cobra species. I will see if I can get a fang shot. I know my buddy too a pic of the females fangs.

Their fange are right under their eyes. So more of a mid fang snake. A simple bite would have venom injected. they have no reason or need to chew really.

I would say they are one of the more dangerous snakes to keep. fast and hot. But one of my favorites lol
