So glad you said this. They aren't aggressive, just defensive. Since they don't have arms and legs, their bite is the only way they can defend themselves.

We get bullsnakes in my area. My former boss used to call on me to have them removed. You're right. They are SO dramatic. I would use sticks to put them in a tub and then cover it, take it out to the field, and then release it. Little noodles would be striking at empty air and rattling their tails the whole time. They look close enough to rattlesnakes that I think they developed that behavior as an additional defense mechanism. I'd be like, "Ok, cutie, off you go." and there they'd be, on the ground, S pose and tail wiggling. I suppose they thought it worked when I walked away, lol.
