Stretch Marks on Boas

[Willie76]

Are they crinkley marks like this? Mine get these from curling up tight. Can you get some pics?

Yes, that is exactly what I am seeing. Awesome pic, Doolittle! Sorry, at work when I decided to ask, but those are exactly what I am seeing. It makes sense as my Hypo male just loves to curl up in his hide and has more of those lines whereas my Crimson boy is a little more active and has fewer. So if I put two and two together, this is more of a lifestyle thing rather than anything to worry about. They're only 300 grams each and are in a divided T8..one on one side, the other on the other side. I have a few more enclosures coming so I'll see if the move to a larger full T8 prompts my Hypo to wander a bit more and stretch...

Thanks everyone!
