Rhabditida
Rhabditida is an order of free-living, zooparasitic, and phytoparasitic 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.Tree of Life Web Project (2002b)Nematoda Version of 2002-JAN-01.

Scottnema
''Scottnema lindsayae'' is a species of nematode belonging to the family Cephalobidae. First described in 1971, it is endemic to Antarctica and most commonly found in the McMurdo Dry Valleys. ''S. lindsayae'', a microscopic worm, feeds on microbes, including bacteria, yeast, and algae. Adapted to very cold and dry climates, its population may be decreasing as a result of climate change. Taxonomy ''S. lindsayae'' is the only described member of ''Scottnema''. Originally described by R. W. Timm (1971), it was named after the polar explorer Robert Scott and the collector of the holotype specimen, Kay Lindsay. Description and lifecycle ''S. lindsayae'' is between half a millimeter and a millimeter in length and between two and four micrometers in width. ''S. lindsayae'' reproduces sexually, with females laying eggs. The minimum observed lifecycle length at is 218 days, with four juvenile stages outside of the egg. As it enters hibernation during Antarctic winters, ''S. lindsaya ...

Nematodes
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-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 arthropods, tardigrades and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular 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 time.
