Cathetocephalidae is a family of flatworms belonging to the order Tetraphyllidea Tetraphyllidea is a large tapeworm order that contains some 60 genera and about 800 described species.

Flatworms
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 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 proven not to be ...

Tetraphyllidea
Tetraphyllidea is a large tapeworm order that contains some 60 genera and about 800 described species. Tetraphyllideans are remarkable for their scolex morphologies, which are the most varied and morphologically complex amongst all tapeworm orders. Tetraphyllidean cestodes also exhibit a remarkable degree of host specificity. The procercoid probably parasitizes copepods, which are eaten by the second intermediate hosts: teleost fishes, decapods or cephalopods, which may also serve as paratenic hosts. The verified definite hosts are sharks, skates and stingrays. Occasionally found in cetaceans, the role of these apex predators in the tetraphyllidean life cycle is not well known; whales and dolphins may be definite or dead-end hosts. '' Crossobothrium antonioi'' is a recently discovered species in the genus '' Crossobothrium'', which belongs to the order Tetraphyllidea. It is a parasitic tapeworm that infects ''Notorynchus cepedianus'', the broadnose sevengill shark. ''C. antonioi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
