Acid Maw is a Tyranid biomorph exhibited through a Tyranid creature's jaws continuously dripping with acidic bile powerful enough to dissolve through ceramite.² Some creatures also have a powerful tongue dripping with corrosive acids that can be used to snare prey and bring them in for consumption and digestion while leaving other limbs free for other tasks.¹
