Metal Print: Fire Drake

This Fire Drake is mid fire breathing. I like to think its getting off some pests. The idea of fireproofing scales has always been fascinating. Would it mean the scales are a form of organic asbestos? Would the dragon's blood itself be something other than water based so the dragon doesn't boil itself? This is a metal print edition of this lovely fire drake. Hang it on the wall and consider, what is the biology of a dragon?
