Helps a lot for us to SEE it. I've seen fungal infections that start that way too- one or few scales. Watch & see if you see more spots* like this; high temps plus high
humidity favors fungal infections on BP skin, btw. If it's a fungal infection, it won't disappear with a shed. Can be treated with a topical, & without treatment, can get
really ugly after you wait a while. *I would describe them more as a changed texture when you look up close...not actually flaking skin. In any case, snakes don't shed that way- a few scales at a time.
Yikes. I had never heard of this. I will take some pictures of her when I get home and post them. It does not appear to be a different texture but like something caused her scale to raise up but not flake all the way off.
