Excuse me but scorpions are all over the world and they all look pretty much alike. The constellation of Scorpio is the one constellation that actually looks like its name. Only people like ancient Eskimos etc. would not know what a scorpion looked like as there are no ice scorpions that we know of.
Tell you what.
Take some bright college students in a desert area, show them a picture of that part of the night sky (not just the constellation, about 90 degrees worth) and ask them what animal shapes they see, if any.
If I remember, I may try it today at work.
