The University of Pennsylvania vet school borrowed some geckos from the blog linked above for a bit of study and xrays. I found these xrays just as fascinating as the owner of these geckos did and asked if I could share them here.
I set the captions to say what kind of lizard they are (and the source blog has a page of information for each individual lizard!), but for the sake of being thorough:
The first pair of images are of a gravid chahoua.
On the gravid chahoua, Belite, you can see how she is pulling calcium from her bones due to how dark the middle of them are with only a thin bright white wall.
The second pair is a male chahoua.
Third is a female gargoyle, fourth is a female leachie and last is a male gargoyle with a regenerated tail.
