What is this? I'm concerned!

[Brit6]

All of my tortoises have these small white deposits inside their shells now after living outside this summer. It looks like it's coming from the inside. Is it a nutrient deficiency? Parasite? Moisture issue? Sun issue? Totally benign?

Please shed some light if you have any idea what this is. I'm worried!

I just see regular shell patterns. I did see some white, squiggy lines (do a sesrch for this) on a couple of them, and that's nothing to worry about.

Ok, great! That's good to hear. Thank you! I read through a bunch of fungal threads on here, and I found one picture that looks like mine do.
