Thanks for the comments!
Bri, there are two different species shown, U. ornata (1-3) and U. geryi (4-5). I keep three species total.
Kenny, not so much a new hobby...more of a rekindled one.
Denis, Beardies are very cool animals--they certainly make for one of the best captive reptiles.
Mark, that I do. They are great to work with.
Michael, what you're seeing is known as 'snalt'...it's basically excess salts that are excreted through the nasal passages. When these salts mix with fluids (snot) they form a liquid substance that dries and crusts over.
