mouthless
Lacking oral cavity
Mouthless means lacking a mouth.
The word appears in biology for organisms without oral openings, in fantasy for creatures or beings depicted without mouths, and in figurative contexts suggesting an inability to speak or consume: The mouthless figures in the painting conveyed silent anguish.
Something mouthless is voiceless, unable to feed, or simply smooth where a mouth would be.
