It looks like a black snake to me. All snakes have somewhat of a triangular head, their jaws have to open so wide to eat. My son has a Ball Python, and his jaws are a bit wide but then he has to swallow a whole rat.
M y sone has a ball python too. He is in college now, so I guess I have a ball python.
They are the most gentle snakes in the world. I believe there is no record of them ever biting a person. Anyway, I wrapped it around my neck and went for a walk in the neighborhood. I talked it up that I have a snake room wit a rattler. I don’t but it made good-tall-tale telling. Anyway, there is probably a much less chance of my house getting burglarized by a bad kid in the neighborhood as a result.
