First off, I'd just like to say I hope I'm putting this in the right place.
So, after a recent discussion regarding a multi-limbed taur, it came to my attention that the wiki is both inconsistent and incorrect. From uni to octo it is -ped, EXCEPT for hexapeds - there it is hexapod. Not only is this inconsistent, but there IS a subtle difference in the two suffixes. -Ped is Latin and used when speaking of a creature's locomotion, however -pod is Greek and used for denoting the number of limbs (excluding wings) a creature has. Now, normally this isn't a problem, almost all tetrapods are quadrupeds...then come along aves and the homo genus, and in the case of e621, fantastical octopodal hexapeds. Oh my!
TL;DR: for consistency and accuracy, the tag hexapod needs to be switched to hexaped.
