Caenorhabditis elegans [SEP] Introduction
Caenorhabditis elegans () is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments. It is the type species of its genus. The name is a blend of the Greek "caeno-" (recent), "rhabditis" (rod-like) and Latin "elegans" (elegant). In 1900, Maupas initially named it "Rhabditides elegans." Osche placed it in the subgenus "Caenorhabditis" in 1952, and in 1955, Dougherty raised "Caenorhabditis" to the status of genus. "C. elegans" is an unsegmented pseudocoelomate and lacks respiratory or circulatory systems. Most of these nematodes are hermaphrodites and a few are males. Males have specialised tails for mating that include spicules.
