... and muscle arrangement were examined in juveniles and adults of the small polychaete Capitella sp. We found that it moves by peristalsis, and no obvious differences were observed among worms of different sizes; even very small juveniles were able to burrow through a clear mud analog by fracture...

... forces against the walls of the crack, and retrograde peristalsis is used to bring the body into the burrow. Moreover, both ends when burrowing exhibited the same four phases, which involve stretching toward the crack tip, pushing into the burrow to further extend the crack, widening the burrowing end...

... basal animals with a nervous system, we investigated the role of NO in peristalsis, an activity that moves body fluids through the coelenteron (gastrovascular cavity) of the polyps across the colony. NO donors increased the amplitude of peristaltic contractions and increased tonic contractions...

... in the gut of insects ( Konopinska and Rosinski, 1999 ). In a variety of insects, proctolin has been shown to induce or stimulate muscle contractions, including gut peristalsis( Orchard et al., 1989 ). In the present study, proctolin induced a dose-dependent reduction of V te (see Fig. 4 ), indicating...
