The marks might just be like scratches from trying to squeeze out of the enclosure. Theyre odd shaped to be burns. Burns would usually be wider on the belly where it has more contact with an unregulated uth. Im guessing its in a fish tank? Do you have a thermostat hooked up to your heat source? Id suggest reading up on the different ways to insulate and keep a tank humid because you shouldnt have to mist to keep humidity where it needs to be and that will solve any shed issues but otherwise doesnt look like much to worry about to me.
