It is important because much research has been done on its [[genetics]] and [[development]]. ''C. elegans'' is about 1 mm long. The worms are not [[parasite]]s, they are free-living. They live in soil and feed on [[bacteria]]. ''C. elegans'' is a [[model organism]], used to study [[animal]] [[development]] and behavior. It is the first [[multicellular organism]] for which [[scientist]]s have been able to sequence its whole [[genom
