In the process of viewing post #43797 and educating myself to the meaning of the term "megrodite", I went back and looked at other Furball images posted to e621 in the past, and found that there's some disagreement going on with the tagging of the gender of these creatures.
It appears that last November, user #2393 did a cleanup of kaisura images, dropping the herm tag from images depicting the megrodite gender type. Since then though, roughly 1/3 to 1/2 of the megrodite images have had the herm tag restored.
I was going to submit an implication for megrodite → herm, but thought I'd create a thread for review and consensus first.
