A scorpion under ultra violet light. In normal circumstances their shape is black. By adding UV light it becomes dark blue. This photograph was taken in complete darkness except the black light which made the scorpion appear very bright and blue - turquoise. It was pretty hard to get a sharp photo because the scorpions were moving around permanently. I don't know if they were annoyed of the black light or if they just didn't recognize it - scorpions are night active.
