What is this mark?

very interesting. did you just notice it? how long have you had the snake and did it just appear? when was the last time he shed? sometimes scales can become discolored after a shed. Honestly, it doesnt look like something id worry about a ton. I'd keep an eye on it and see what it looks like after his next shed. I would hold off on the vet visit for now. No reason to stress the little dude out

Last shed was about a month ago, he didnt do well because I was trying a new tank situation and the humidity wasnt high enough so it was a really flakey shed, but after a warm bath it all came off. Not sure on how long it's been there, a friend noticed it when he was handling him and the snake jumped back when he touched the marks, which was about a week ago
