CestodaCestoda is a class of parasitic worms in the flatwormphylum (Platyhelminthes). Most of the species—and the best-known—are those in the subclass Eucestoda; they are ribbon-like worms as adults, commonly known as tapeworms. Their bodies consist of many similar units known as proglottids—essentially packages of eggs which are regularly shed into the environment to infect other organisms. Species of the other subclass, Cestodaria, are mainly fish-infecting parasites.
GyrocotylideaGyrocotylidea is an order of Cestoda (tapeworms). Members of this order are parasites of vertebrates, living in the coelom (the body cavity). Gyrocotylidea are a subspecies of the tapeworm that is mainly a parasite of fishes and turtles. They do not have a gut, thus being classified with Cestodes.
AmphilinidaeAmphilinidae is a family of parasiticflatworms of the phylumPlatyhelminthes. It is the only family in the monotypicorderAmphilinidea. Amphilinids are Cestodes, yet differ from true tapeworms (Eucestoda) as their bodies are unsegmented and not divided into proglottids. "Amphilinids are large worms which have a flattened leaf-like body. Only 8 amphilinid species are known." "The adults are hermaphroditic.*As an Amazon Associate I earn from qualifying purchases.
