A marked, relatively rapid retrograde peristaltic activity was observed in the pyloric region of Atlantic halibut Hippoglossus hippoglossus in vitro and in vivo. This could provide a mechanism for filling the pyloric caeca, and the retrograde contraction could also be involved in mixing the chyme with digestive secretions in the region of the pyloric caeca.
