Caenorhabditis Elegans
C. elegans ( abbreviation for Caenorhabditis Elegans ) is a non-hazardous, non-infectious, non-pathogenic, non-parasitic organism. It is small, growing to about 1 mm in length, and lives in the soil—especially rotting vegetation—in many parts of the world, where it survives by feeding on microbes such as bacteria. There are two sexes: a self-fertilizing hermaphrodite and a
male. The adult essentially comprises a tube, the exterior cuticle, containing
two smaller tubes, the pharynx and gut, and the reproductive system. Most of
the volume of the animal is taken up by the reproductive system. C.elegans
lives in the soil and is found all around the world. You even might find some
in your flower pot. They are most likely in your garden and almost certainly in
a rotten apple picked from the ground. Like all Nematoda, the C. Elegans does not have a endo or exoskeleton, but a hydroskeleton.
