While compiling the big ol' list of critters in my previous post, I came across several Wikipedia pages which contained lists of animals with their common names. These lists are incomplete and have some duplicates, but they are nice pieces of work nonetheless. I've copied them here, cleaned them up, tried to remove duplicates, and transmogrified them into a form suitable for random generation.
