"Why do Spider Mon not have 8 legs?"

So Galvantula has been my favorite pokemon since I first played gen 5, but it was only today that I realized it only has 4 legs. It's tagged as the Elespider pokemon in the pokedex, so why does it only have 4 legs! It's like this on all the spider mon. Araquanid has 6, Ariados has 4, Spinark has 6, like why though? My only guess is that they didn't want to creep people with arachnaphobia out, but if there's an official reason I'd love to hear it as I couldn't find one when I was looking. via /r/pokemon https://ift.tt/3k6kesw
