This is a strange thing, and not important at all, but...has anyone else noticed that there is a distinct gender difference in Twill'ek ears? The males have human-looking ears, and the females all have those funky cone-bump ears. I thought at first that it was part of their headgear that covers their ears, but it's the same on female Twill'eks with no head gear.

What's up with that? Now that I've noticed it, I see it all the time.

Really? I know that there is a difference, I am not asking about that, but you made a post to point this out? Really? 2 Links to busts of the first 2 Twil'eks seen in Return of the Jedi. Notice Bib has ears, notice Oola does not.
