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.
Tylenchidae is a family of nematodes. They are an important group of soil dwelling species that frequently contributes as much as 30% to the nematode species richness of soil samples. [ 2 ] They diverged relatively early on and many species pose little risk to economically important plant species. [ 2 ]
Rhabditida is an order of free-living, parasitic and microbivorous nematodes living in soil. The Cephalobidae, Panagrolaimidae, Steinernematidae, and Strongyloididae seem to be closer to the Tylenchia, regardless of whether these are merged with the Rhabditia or not. [1]
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.
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.
A complete reproductive lifecycle of the stem and bulb nematode is 19–25 days (egg to egg). Reproduction takes place in succulent, rapidly growing tissues or in storage organs and continues throughout. [13] A female can lay 200–500 eggs in her lifespan. [12] However, if conditions are unfavorable, the nematodes can halt their lifecycle. [13]
Enoplida is an order of nematodes. It is one of two orders in Enoplia, which is one of two subclasses in Class Enoplea. [1] [2] These nematodes are mostly free-living marine animals. [3] Most feed on diatoms and other algaes. [1]
