Enoplea
Enoplea (enopleans) is a class, which with the classes SecernenteaTree of Life Web Project (ToL) (2002)Nematoda Version of January 1, 2002. Retrieved November 2, 2008. and Chromadorea make up the phylum Nematoda in current taxonomy. The Enoplea are considered to be a more ancestral group than the Chromadorea, and researchers have referred to its members as the "ancestrally diverged nematodes", compared to the "more recently diverged nematodes" of Chromadorea. Description The Enoplea are distinguished from the Chromadorea by a number of characteristics. The enoplean esophagus is cylindrical or "bottle-shaped", compared to the bulbous chromadorean esophagus. Enopleans have pocket-like amphids, while chromadoreans have amphids shaped like slits, pores, coils, or spirals. An enoplean is smooth or marked with fine lines, while a chromadorean may have rings, projections, or setae. The enoplean excretory system is simple, sometimes made up of a single cell, while chromadoreans have more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dorylaims
Dorylaimia is a subclass of nematodes. Description In general, members of subclass Dorylaimia exhibit a great diversity of terrestrial and freshwater species, most of which are large predators or omnivorous free-living species. Some are plant parasites, whereas others are animal parasites (Trichinellida and Mermithida). No members of the Dorylaimia are found in marine habitats. Dorylaimia bear an odontostyle, a protrusible, hollow, needlelike tooth for puncturing and emptying food items. Taxonomy Phylogenetic analysis of phylum Nematoda suggests three distinct basal clades, the dorylaims, enoplids, and chromadorids. These represent Clades I, II and C+S of Blaxter (1998). Of these, the first two appear to have sister clade status, allowing resolution into two classes, Enoplea and Chromadorea, and division of the former into two subclasses corresponding to Clades I and II respectively, the Enoplia and Dorylaimia. Nevertheless, the possibility remains that Dorylaimia will ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mermithida is an order of nematode worms. The order includes two families, and most members are endoparasites on arthropods.

Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-Parasitism, parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with Arthropod, arthropods, Tardigrade, tardigrades and other moulting animalia, animals in the clade Ecdysozoa, and unlike platyhelminthe, flatworms, have tubular digestion, digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over ...

Dorylaimida
Dorylaimida (dorylaims) is a diverse order of nematodes with both soil and freshwater species. Taxonomy History The order originated with the description of ''Dorylaimus stagnalis'' by Dujardin in 1845, and in 1876 De MAn proposed the family Dorylamidae, while Cobb added many other genera and subgenera. In 1927 Filipjev added a subfamily, Dorylaiminae, and by 1934 there were four subfamilies. That was when Thorne raised family Dorylaimidae to superfamily Dorylaimoidea. In 1936 Pearse raised it further to become a suborder of Enoplida, and in 1942 Pearse proposed the current order, Dorylaimida to encompass all of the dorylaim nematodes. Many reorganisations followed. For instance Clark (1961) did not accept Dorylaimida, whereas Goodey (1963) did. Other reclassifications include Jairajpuri (1964, 1969, 1976, 1980, 1983, 1992), Thorne (1964, 1967), Siddiqui (1968, 1983), Andrássy (1969, 1976), and Coomans and Loof (1970).

Enopla
Enopla is one of the classes of the worm phylum Nemertea, characterized by the presence of a peculiar armature of spines or plates in the proboscis. Evolution and systematics The record of nemerteans is extremely sparse, as would be expected from a soft-bodied animal. The Cambrian fossil, '' Amiskwia'', has been interpreted as a nemertean based on its resemblance to some pelagic ribbon worms; however, this interpretation is disputed by many paleontologists. The enoplan nemerteans have been regarded as highly derived based on a more complicated muscle arrangement in the body wall and a more complex nervous system. However, whether this is a plesiomorphic or apomorphic character is not clear, and recent molecular studies are inconclusive in this respect. Class Enopla used to be divided in two subclasses, Hoplonemertea and Bdellonemertea, but recent phylogenetic analyses based on nucleotide sequences show that Bdellonemertea should be included in Hoplonemertea. Hoplonemertea ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
