• Antique engraved illustration of the tapeworm. Vintage illustration of the cestoda. Old engraved picture. Book illustration published 1907. Cestoda is a class of parasitic worms in the flatworm phylum (Platyhelminthes). Most of the species and the best-known are those in the subclass Eucestoda they are ribbon-like worms as adults, 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. All cestodes are parasitic many have complex life histories, including a stage in a definitive (main) host in which the adults grow and reproduce, often for years, and one or two intermediate stages in which the larvae develop in other hosts. Typically the adults live in the digestive tracts of vertebrates, while the larvae often live in the bodies of other animals, either vertebrates or invertebrates. For example, Diphyllobothrium has at least two intermediate hosts, a crustacean and then one or more freshwater fish its definitive host is a mammal. Some cestodes are host-specific, while others are parasites of a wide variety of hosts. Some six thousand species have been described probably all vertebrates can host at least one species.
