WebCaenorhabditis is a genus of nematodes which live in bacteria-rich environments like compost piles, decaying dead animals and rotting fruit. The name comes from Greek: caeno- (καινός (caenos) = new, recent); rhabditis = rod-like (ῥάβδος (rhabdos) = rod, wand). In 1900, Maupas initially named the species Rhabditis elegans, Osche ... WebC. elegans is a small, free-living nematode found in decaying plant material, especially compost and mushroom beds in temperate regions throughout the world. It feeds on the bacteria and other microorganisms associated with plant decay, and is frequently found associated with snails, slugs, millipedes, mites and pill bugs, which are presumed to ...

WebDec 11, 1998 · Caenorhabditis elegans is a rhabditid nematode, part of a diverse assemblage of microbivorous soil-dwelling species. These were traditionally classified in a distinct order from other free-living species (the diplogasterids, such as Pristionchus pacificus) and parasitic orders. Molecular phylogenetic analysis with ribosomal small … Caenorhabditis elegans is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments.
