Simply enough, most Maxis creations' pages have never been made. This is because making pages for them is a long process of finding all of the stats, taking a screenshot, putting these into an infobox, and then writing a summary alongside it. It's a time-consuming process for no reward.

It has been proposed that we simply get rid of creature and flora pages entirely, and just have a single database of each creation's name + stats + image, because that's all of the information that actually comes from the game. But that hasn't happened either, presumably because it too would be a time-consuming process for no reward.
