The dilatation is often accompanied by a paralysis of the peristaltic movements of the bowel.

The fluid accumulation alters the stool consistency, distends the bowel, and induces peristaltic movement.

Nymphs emerge from the eggs through peristaltic movements and with the help of an internal nearly H-shaped structure in the egg known as the 'egg burster'.

When hatching, the prolarva (the advanced embryo) exit the egg by opening the lid through peristaltic movements and with the help of a T-shaped internal structure in the egg (known as the egg burster).

Many can move on the surface or burrow through sand or mud using peristaltic movements and some have short tube feet on their under surface with which they can creep along in the manner of a starfish.

Peristaltic movement is initiated by circular smooth muscles contracting behind the chewed material to prevent it from moving back into the mouth, followed by a contraction of longitudinal smooth muscles which pushes the digested food forward.
