Is it natural for a boa (BCI) to have black splotches inside its mouth, or should the entirety inside the mouth be pink? I ask because Leonard was realigning his jaw post-meal and I saw what looked like black pigmented splotches in two places and I don't know if I should freak and call the vet Monday or if he's just fine and has different natural pigmentations in his mouth.

For what it's worth, his temps range from 78 to 88, he's at 60+% humidity, he's eating, defecating, and has shed for me once thus far. There's no slimy discharge, no sound of wheezing... so there's nothing "off" except for this odd coloration.

Thank you for any info you all can offer. I'm googling like a madwoman, but I must not be using the right words because I'm not getting any relevant results.
