The theme today for Life Photo Meme at Adventures of a Free Range Urban Primate blog is "ancient."
If you spend time observing scorpions, you get the sense that these creatures have been around for eons. They seem to be the epitome of the word ancient.
(Sorry about the focus, I tend to stand too far away from live scorpions to get a good photograph. :-))
Ants can be significant predators of scorpions.
