Cestodaria

	Cestodaria Cestodaria is one of two subclasses of the class Cestoda. The Cestodaria subclass is made up of Amphilinidea and Gyrocotylidea Gyrocotylidea is an order of Cestoda (tapeworms). Members of this order are parasites of vertebrates, living in the coelom The coelom (or celom) is the main body cavity in most animals and is positioned inside the body to surround and contain ....

picture info	Cestoda 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 fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Australamphilina ''Australamphilina elongata'' is a species of parasitic worm in the order Amphilinidea. Amphilinids are commonly considered to be tapeworms, yet differ from true tapeworms, subclass Eucestoda, because their bodies are unsegmented and are not divided into proglottids. It is an internal parasite of freshwater turtles including the eastern long-necked turtle (''Chelodina longicollis''). It is found in eastern Australia. Description Unlike other tapeworms, the body of amphilinids is not divided into segments, instead being leaf-shaped and laterally flattened. There is a proboscis and several frontal glands at the anterior end, and an ovary and a seminal receptacle at the posterior end. The uterus extends from the posterior end, forward to the anterior end, back to the posterior end and then forward again to the anterior end, before opening at the female gonopore. Small testes and yolk cells are scattered throughout most of the tissue. The male gonopore is at the posterior end, and the ...

	Amphilinidea Amphilinidae is a family of parasitic flatworms of the phylum Platyhelminthes. It is the only family in the monotypic order Amphilinidea. 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. A muscular proboscis is located at the anterior end, and is sometimes very weakly developed or absent." They live in the body cavities of freshwater turtles and teleost fish as adults, and in the bodies of various crustaceans as juveniles. Apart from a little studied parasitism of sturgeon, these flatworms have very little economic importance. Biologically, they have gained attention for their potential to shed light on the phylogeny of tapeworms.

	Gyrocotylidea Gyrocotylidea is an order of Cestoda (tapeworms). Members of this order are parasites Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life.
