gravescratch:

My dentae are primarily made for crushing and grinding, and my jaw hinge allows me to shift my lower jaw back and forth in a sawing motion if I need to (roughly) sever something. If I need to tear into a larger meal, I generally transform the lower jaw of my alt mode into place so I can use the sharp fangs. When my mouth is closed, my dentae retract slightly to save space, and if I am not using them, I can keep them retracted with my mouth open in order to avoid threatening people. 

#nervous sweating#I SHOULD MAYBE NOT HAVE PUT MY HANDS SO CLOSE TO THAT MOUTH

You’re quite nice. I’m not about to bite the hand that pets me. 

Except if it’s condescending “look at the tracker dog being a good boy” helm-patting, because then I will bite it off.
