The entire muscular system of the cercaria of D. pseudospathaceum was studied using a wholemount fluorescence technique with rhodamine-labelled phalloidin. The body-wall musculature of the main body consists of circular, longitudinal and diagonal muscles. The musculature of the tail, anterior organ, ventral sucker, and certain parts of the alimentary tract are distinct. The ultrastructure of the two main types of muscle cells (smooth and cross-striated) were described, as was the differentiation of smooth muscles in particular organs. Muscle cells with two major opposing systems of myofilaments were found in the oesophagus.
