Dry skin

[Bogertophis]

BTW, what substrate is used in her enclosure?

Specifically, what "looks fungal" to me are the way some of her rostral scales look puckered or shriveled* (-they don't appear to be abraded, as if healing from rubbing on things) and a snake's eyes don't normally cloud up on their own way ahead of the rest of a snake's body (if this was a normal shed). *BTW, that's something I HAVE seen & treated on a couple snakes in person, after the vet verified it was fungal. It responded to the topical medication from my vet, but was not on the snake's face, near eyes, nose & mouth, & it was addressed while much less noticeable.

Your snake's issue simply reminded me of the photos* & information I've seen about the fungal disease in wild snakes (*many with their head very much affected), but that's not the only fungus around that can infect a captive snake's skin. Any issue that affects a snake's face (eyes, mouth, nose, etc) impacts their overall health- btw, I'm glad you don't put your snake on the ground outside- I know many like to do that, but I sure don't either. Anyway- I hope you get some answers that resolve this- I still hope I'm wrong, but you asked.
