Caenorhabditis elegans
Caenorhabditis elegans (pronounced /ˌsiːnɵræbˈdaɪtɪs ˈɛlɪɡænz/) is a free-living, transparent nematode (roundworm), about 1 mm in length, which lives in temperate soil environments. Research into the molecular and developmental biology of C. elegans was begun in 1974 by Sydney Brenner and it has since been used extensively as a model organism.
