There are no free-living trematodes and all species parasitic to humans require at least one intermediate host, typically a snail, to complete their life cycle. Some species also require a second intermediate host, such as a fish (clonorchis sinensis) or crab (paragonimus westermani). Trematodes possess a cellular epithelial covering, or tegument, that protects the parasite from host immune factors and serves as an absorptive surface for the acquisition of nutrients.

Parasitic worms have armies, and produce more soldiers when needed. In estuaries around the world, tiny trematode worms take over the bodies of aquatic snails. These parasitic flatworms invade the snail’s body and use its systems to support their colony, sometimes for over a decade, “driving them around like cars,” according to senior author ryan hechinger, professor of marine sciences at scripps institution of oceanography at the university of california san diego.
Along with the cestodes, the trematodes belong to the phylum platyhelminthes. Trematodes are flatworms and generally have: o flattened bodies, o a blind alimentary tract, o suckers for attachment to their hosts, o are hermaphrodites. The class trematoda historically was split into two subclasses: monogenea, which includes important ectoparasites of fish, and digenea, including species parasitic in the bile ducts, alimentary and respiratory tracts, and blood vessels of vertebrates.
