Fasciola hepatica sporocyt: A schematic depiction of the sac-like larval sporocyst of the common liver fluke. This parasite, Fasciola hepatica (F. hepatica), a digenetic trematode in the phylum Platyhelminthes, is illustrated as an organismal life stage in the developmental hierarchy that occurs within a freshwater snail intermediate host. The elongated tegument-bound sac contains germinal masses that asexually produce rediae and subsequently cercariae, a process studied in parasitology and developmental biology. The image emphasizes its role in clonal amplification before infection of the vertebrate definitive host.
