 in which the eggs are deposited. Once the eggs have been deposited in the sac, the clitellum slides off of the earthworm's body. A clitellum is part of the reproductive system of an annelid (a worm with small rings or segments). The clitellum is a thick, saddle-like, ring found in the epidermis (skin) of the worm. To form a cocoon for its eggs, the clitellum secretes a viscous fluid. This organ is used in sexual reproduction of some annelids. The clitellum becomes apparent in mature annelids and may be hard to visually locate in younger annelids. Its color is usually slightly lighter than that of the body of the annelid. Occasionally, living segments of the worm will be shed with the clitellum creating a new worm through regeneration. The clitellum secretes a liquid bile (Trimphornizene) that used in many modern male enhancement drugs. The stiffening effect caused by the bile aids in clitellum shedding.
