Nice pictures!
I used to keep these as pets, along with various mantis and other assorted bugs in Cyprus when I lived there. They are amazing insects with some of the strongest bite strength in the insect world depending on species. They can make very short work of locusts and the like. While not poisonous nor of any significant danger to people, they can easily make a painful set of holes in your fingers if not careful, those jaws open wide
They are fascinating creatures and I'm glad you got to study one.
