Rhabditida
Caenorhabditis elegans
Scientific classification
Kingdom:	Animalia
Phylum:	Nematoda
Class:	Chromadorea
Subclass:	Chromadoria
Order:	Rhabditida Chitwood, 1933
Suborders
Myolaimina Rhabditina Spirurina Tylenchina

Rhabditida is an order of nematodes that can be found as free-living organisms, parasites, or microbivores 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]
