Morphology

antiperistaltic = peristaltic (semi-transparent) = anti + peristalt + ic

The prefix anti- clearly signals opposition, and it is directly attached to the technical adjective peristaltic.

Etymology

Antiperistaltic comes from the common prefix anti- meaning 'against' and peristaltic, from peristalsis, the muscle 'wave' that pushes food along the gut. Think of peri- as in perimeter meaning 'around', so antiperistaltic describes movement that goes 'against' the normal squeezing wave and therefore means motion in the opposite direction to normal peristalsis.
