Tenuisentidae
Tenuisentidae is a family of parasitic spiny-headed (or thorny-headed) worms. The family contains two genera, each with one species. Description and taxonomy Species There are two genera, each with a single species. ''Paratenuisentis'' Bullock and Samuel, 1975 * ''Paratenuisentis ambiguus'' (Van Cleave, 1921) ''P. ambiguus'' infects the European eel (''Anguilla anguilla''). ''Tenuisentis'' Van Cleave, 1936 * ''Tenuisentis niloticus'' (Meyer, 1932) ''T. niloticus'' was found infecting the small intestine of the African arowana (''Heterotis niloticus''). The species name ''niloticus'' derives from the species name of the host fish, also ''niloticus''. It has also been found in the Egyptian Nile and River Sourou at Di, Sourou Province, Burkina Faso, Sudan and Mali. It has also been found in the electric catfish (''Malapterurus electricus'') in Lekki Lagoon, Lagos, Nigeria.Pak J Biol Sci. 2007 Feb 1;10(3):427-32.

Dendronucleatidae
Dendronucleata is a genus of small parasitic spiny-headed (or thorny-headed) worms. It is the only genus in the family Dendronucleatidae. This genus contains three species that are distributed globally, being collected in North America and Asia. The distinguishing features of this genus among Archiacanthocephalans is the presence of randomly distributed dendritically branched giant hypodermic nuclei. ''Dendronucleata'' parasitize freshwater fish and a salamander by attaching themselves in the intestines using their hook covered proboscis and adhesives secreted from cement glands. Taxonomy and Description The general appearance, shape of proboscis and number and arrangement of proboscis hooks of the Dendronucleatidae are similar to members of Neoechinorhynchus of the family Neoechinorhynchidae, Dendronucleatidae have randomly distributed dendritically branched giant hypodermic nuclei from which it derives its name.

Eoacanthocephala
Eoacanthocephala is a class of parasitic worms, within the phylum Acanthocephala. They feed on any aquatic cold-blooded creature such as turtles and fish. Their proboscis spines are arranged radially, with no protonephridia, and with persistent ligament sacs in female. The only reliable way to identify the group is that they only have one cement gland. This is a primitive characteristic and hence the name. The class contains 2 orders Order, ORDER or Orders may refer to: * Categorization, the process in which ideas and objects are recognized, differentiated, and understood * Heterarchy, a system of organization wherein the elements have the potential to be ranked a number of d ...: * Gyracanthocephala Van Cleave, 1936 * Neoechinorhynchida Southwell and Macfie, 1925 References *Robert L.

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Parasitic Worm
Parasitic worms, also known as helminths, are large Parasitism#Basic concepts, macroparasites; adults can generally be seen with the naked eye. Many are intestinal worms that are soil-transmitted helminth, soil-transmitted and intestinal parasite infection, infect the gastrointestinal tract. Other parasitic worms such as schistosomes reside in blood vessels. Some parasitic worms, including leeches and monogeneans, are ectoparasites thus, they are not classified as helminths, which are Parasitism#Basic concepts, endoparasites. Parasitic worms live in and feed in living host (biology), hosts. They receive nourishment and protection while disrupting their hosts' ability to absorb nutrients. This can cause weakness and disease in the host, and poses a global health and economic problem. Parasitic worms cannot reproduce entirely within their host's body; they have a life cycle that includes some stages that need to take place outside of the host. Helminths are able to survive in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthocephala
Acanthocephala (Greek , ', thorn + , ', head) is a phylum of parasitic worms known as acanthocephalans, thorny-headed worms, or spiny-headed worms, characterized by the presence of an eversible proboscis, armed with spines, which it uses to pierce and hold the gut wall of its host. Acanthocephalans have complex life cycles, involving at least two hosts, which may include invertebrates, fish, amphibians, birds, and mammals. About 1420 species have been described. The Acanthocephala were thought to be a discrete phylum. Recent genome analysis has shown that they are descended from, and should be considered as, highly modified rotifers. This unified taxon is known as Syndermata. History The earliest recognisable description of Acanthocephala – a worm with a proboscis armed with hooks – was made by Italian author Francesco Redi (1684).Crompton 1985, p. 27 In 1771, Joseph Koelreuter proposed the name Acanthocephala. Philipp Ludwig Statius Müller independently called th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
