For characters with a [[tail]] noticeably longer than their legs.

In the case of [[monster_girl|monster girls]] or other characters with a single "tail" in place of legs, use your judgment on what constitutes "long" for their kind.  For example, a [[mermaid]] with a tail noticeably longer than human legs would fit this tag, while a [[lamia]] might need a tail three times as long as human legs to stand out.

If it's a close call in your mind, err towards not using this tag.
