    (*Note: Some of the colors seen under UV light in said photos may have been enhanced for effect. Because UV is invisible to our eyes, it is difficult to determine how UV induced colors may actually appear to the eyes of those reptiles (yes, many reptiles can see at least part of the UV spectrum) or arthropods capable of doing so.)
