Enoplia is regarded as the earliest nematode branch, according to recent phylogenetic analysis. [5] Enoplia is mentioned as a sister clade to Dorylaima and Chromadoria. [ 5 ] [ 6 ]
The Camallanida are an order of nematodes. They are parasites of terrestrial and aquatic vertebrates. They also use copepods as obligatory secondary hosts. [citation needed] They are sometimes included in the Spirurida as a suborder Camallanina. [citation needed]
This wound on the fish then heals, leaving almost no scarring. Species of Philometra require two hosts to complete their life cycle. After the larval worms are released from the host fish, they are ingested by copepods which act as an intermediate host. Once inside the copepod, the larvae molt several times. Fish may then eat the infested copepod.
Enoplea (enopleans) is a class, which with the classes Secernentea [1] and Chromadorea make up the phylum Nematoda in current taxonomy. [2] [3] [4] 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.
Turbatrix aceti (vinegar eels, vinegar nematode, Anguillula aceti) are free-living nematodes that feed on a microbial culture called mother of vinegar (used to create vinegar) and may be found in unfiltered vinegar. They were discovered by Pierre Borel in 1656. [1]
Myleusnema bicornis is an intestinal parasite of Myleus ternetzi, or "Ternetz's Silver Dollar", a freshwater Characoid fish commonly found in the French Guiana river. [1] M. bicornis has several unusual morphological characteristics, namely the two postcloacal "horns" in the posterior of males, and a separate elongated cephalic region (head) that may be extended and retracted. [2]
Capillaria is a genus of nematodes in the family Capillariidae (or Trichinellidae, according to some classifications).. The taxonomy of the Capillariidae is disputed, with species included within either the single genus Capillaria or 22 different genera (Amphibiocapillaria, Aonchotheca, Baruscapillaria, Calodium, Capillaria, Capillostrongyloides, Crocodylocapillaria, Echinocoleus, Eucoleus ...
The genus Anisakis was defined in 1845 [2] by Félix Dujardin as a subgenus of the genus Ascaris Linnaeus, 1758.Dujardin did not make explicit the etymology, but stated that the subgenus included the species in which the males have unequal spicules ("mâles ayant des spicules inégaux"); thus, the name Anisakis is based on anis-(Greek prefix for different) and akis (Greek for spine or spicule).
