Tetrabothriidea

	Tetrabothriidea Tetrabothriidea is an order of helminths in the class Cestoda. It consists of only one family, Tetrabothriidae. Their hosts are mainly seabirds, the rest being cetaceans and pinnipeds. Genera All of the genera of Tetrabothriidea are in the family Tetrabothriidae. * '' Anophryocephalus'' Baylis, 1922Baylis, H.

picture info	Eucestoda Eucestoda, commonly referred to as tapeworms, is the larger of the two Class (biology), subclasses of flatworms in the class Cestoda (the other subclass is Cestodaria). Larvae have six posterior hooks on the scolex (head), in contrast to the ten-hooked Cestodaria. All tapeworms are Parasitism, endoparasites of vertebrates, living in the digestive tract or related ducts. Examples are the pork tapeworm (''Taenia solium'') with a human Host (biology)#Definitive and secondary hosts, definitive host, and pigs as the Host (biology)#Definitive and secondary hosts, secondary host, and ''Moniezia expansa'', the definitive hosts of which are ruminants. Body structure Adult Eucestoda have a white-opaque dorso-ventrally flattened appearance, and are elongated, ranging in length from a few millimeters to 25 meters. Almost all members, except members of the orders Caryophyllidea and Spathebothriidea, are polyzoism, polyzoic with repeated sets of reproductive organs down the body length, and al ...

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]
	Karl Rudolphi Karl Asmund Rudolphi (14 July 1771 – 29 November 1832) was a Swedish-born German naturalist, who is credited with being the "father of helminthology". Life Rudolphi was born in Stockholm to German parents. He was awarded his PhD in 1793 and his medical doctorate in 1794 from the University of Greifswald, where he was appointed Professor of Anatomy. He worked widely across the fields of botany, zoology, anatomy and physiology. He investigated the anatomy of nerves, carried out studies of plant growth and was an early champion of the view that the cell is the basic structural unit of plants. In 1804, Karl Rudolphi, along with J.H.F. Link were awarded the prize for "solving the problem of the nature of cells" by the Königliche Societät der Wissenschaft (Royal Society of Science), Göttingen, for proving that cells had independent rather than common walls. His first great publication was a study of parasitic worms, the ''Enterozoorum Sive Vermium Intestinalium Historia Nat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Flatworm The flatworms, flat worms, Platyhelminthes, or platyhelminths (from the Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates. Unlike other bilaterians, they are acoelomates (having no body cavity), and have no specialized circulatory and respiratory organ (anatomy), organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. The digestive cavity has only one opening for both ingestion (intake of nutrients) and egestion (removal of undigested wastes); as a result, the food cannot be processed continuously. In traditional medicinal texts, Platyhelminthes are divided into Turbellaria, which are mostly non-parasitic animals such as planarians, and three entirely parasitic groups: Cestoda, Trematoda and Monogenea; however, since the turbellarians have since been prove ...
