Any one knows when or why Tail_mouth became a species tag?

"Has a mouth, must be a separate entity!"
(No idea when it happened, though)

i guess someone though tail mouth as in species category that's definitive trait is to have tail as mouth. similar to scalie or something.

The tailmouth species is quite popular on FA, but I think I originated on DA: http://tailmouth.deviantart.com/.

Looks like it got recently aliased to tail_mouth, which used to be a general tag for mouths on tails. Hm. I guess we could tag the actual species as tailmouth_(species) and implicate that to tail_mouth...? The species is easy to recognize and tag by the shape:

Since nobody objected to the above, I sorted them to tailmouth_(species). Though the tail_mouth tag also obviously applies.

I might've made a couple of mistakes when tagging those: some actual tailmouths were probably left untagged, and some that I tagged as such might not belong in the species. Hard to tell. Tailmouth is an open species, so it tends to get drawn in multiple styles.

Tail_mouth still needs to be changed to a general tag.
