…a species of free-living nematode worm that boasts a cosmopolitan distribution. C.elegans are mostly found in rotting fruit and moist soil and adults will feed on a variety of bacteria. C.elegans eggs are laid by a hermaphroditic adult after hatching they will go four stages (L1-L4) where they will develop. It takes about 14 hours to complete these stages and sperm/oocytes are produced in the L4 stage. If the nematode is crowded or in the absence of feed it will enter a dauer stage, in the dauer stage the larvae will become stress-resistant and will not age.
C.elegans is a common sight in laboratories as it is used as a model organism for animal development. C.elegans was even the first multicellular organism to have its genome sequenced.
