This worm is a well-studied model organism for developmental biology, systems biology, and genetics

Lineage: Eukaryota[13895]; Metazoa[6624]; Ecdysozoa[2886]; Nematoda[172]; Chromadorea[157]; Rhabditida[155]; Rhabditina[63]; Rhabditomorpha[49]; Rhabditoidea[28]; Rhabditidae[28]; Peloderinae[18]; Caenorhabditis[18]; Caenorhabditis elegans[1]
Caenorhabditis elegans, a free-living soil nematode, is widely used as a model organism. It is transparent, and consists of 959 somatic cells. This easily cultured worm provides a model for complex organ systems, as well as developmental biology and genetics. Caenorhabditis elegans was the first multicellular eukaryotic genome to be completely More...
