Cercaria (the larval stage of hermaphroditic generation in Trematoda) has a unique specialized organ of locomotion – the tail. Its musculature is poorly studied, so I took a wide range of cercariae (16 species) with different tail morphology and type of development to describe and analyze the diversity of its musculature organization. The general pattern of muscle elements arrangement was proposed. It includes outer layer of circular, transverse or semicircular muscle fibers, and inner layer of longitudinal musculature divided into several groups: dorsomedial and ventromedial minor bands of smooth fibers, and four lateral bands of cross-striated fibers. However there were many specific characters some of which outlined large trematode taxa, like additional ventrolateral and dorsolateral longitudinal bundles – in Xiphidiata.
