A simple diagram to show the difference between the teguments of free-living and parasitic flatworms: a. shows the syncytial epithelial tegument found in parasitic flatworms, such as F. hepatica. b. shows the multicellular, nonsyncytial, epithelia, found in nonparasitic, free-living flatworms.

Life cycle of the eucestode Taenia: Inset 5 shows the scolex, which has four Taenia solium, a disk with hooks on the end. Inset 6 shows the tapeworm's whole body, in which the scolex is the tiny, round tip in the top left corner, and a mature proglottid has just detached.
