Caenorhabditis elegans (C. elegans) is a 1-1.5mm-long nematode that lives in soil and feeds on bacteria such as Escherichia coli (E. coli). Most C. elegans are hermaphrodites, or self-fertilizing. C. elegans is a popular model organism in a variety of biological research due to its short lifespan, its ability to self-reproduce, and its small size. Additionally, its translucent body enables easy visualization of cells tagged with fluorescent proteins. For neuroscience research in particular, C. elegans is a favored model because it is the first animal to have its entire genome sequenced. The adult hermaphrodite C. elegans has 302 neurons, and the connectome of the C. elegans nervous system has been extensively documented and is widely available in databases such as Wormbook and OpenWorm.
