The nematodes (/ ˈ n ɛ m ə t oʊ d z / NEM-ə-tohdz or NEEM-; Ancient Greek: Νηματώδη; Latin: Nematoda), roundworms or eelworms constitute the phylum Nematoda. Species in the phylum inhabit a broad range of environments. Most species are free-living, feeding on microorganisms, but many are parasitic.
Nematoida is a clade of pseudocoelomate free living or parasitic animals.It consists of phyla Nematoda and Nematomorpha. [3] [4] The two groups share a number of features in common; the presence of a cloaca in both sexes, aflagellate sperm, and a cuticle made of collagen.
The Rhabditidae are a family of nematodes which includes the model organism Caenorhabditis elegans. Genera. Movement of wild-type C. elegans C. elegans hermaphrodite.
Phasmids are sensilla in the lateral tail region of certain species of nematodes. [1] They are similar in their structure to amphid sensilla, but smaller. [2] [3]: 154 One classification system for nematodes places nematodes with phasmids into class Secernentea and nematodes without phasmids into class Adenophorea.
Ascaris is a nematode genus of parasitic worms known as the "small intestinal roundworms". [1] One species, Ascaris lumbricoides , affects humans and causes the disease ascariasis . Another species, Ascaris suum , typically infects pigs .
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.
Nematodes (Nematoda or roundworms) are a phylum of animals. The phylum is subdivided in 3 classes : Chromadorea, Enoplea and Secernentea. ... Nematode anatomy (1 C ...
[4] [5] The dauer state is given other names in the various types of nematodes such as ‘diapause’ or ‘hypobiosis’, but since the C. elegans nematode has become the most studied nematode, the term ‘dauer stage’ or 'dauer larvae' is becoming universally recognised when referring to this state in other free-living nematodes.
