comment #8958 It would seem to me that the artist probly did not know, as they drew the inner mouth, but left it resting inside the outer. But going on my own guess, and remebering how in the movie Alien3 the xenomorph used its inner mouth to eat with. (Do Xenomorps even drink for that matter???) It would probly lean its head back, and cup its inner mouth against the tea cup to drink.
