What is it about spiders, especially black shiny ones, that brings out the ICK factor and the OOG factor. I’d rather deal with the guy on the left, and I really don’t want to do that at all. There’s something about radial symmetry - having lots of legs in a radial pattern that is somehow frightening to our brains, I think. Remember the fence around the forbidden lands in Planet of the Apes? It looked like big spiders to me and scared me as a kid.
