Together, they form the clitellum, which is important in reproduction.
2.
Occasionally, living segments of the worm will be shed with the clitellum.
3.
To form a cocoon for its eggs, the clitellum secretes a viscous fluid.
4.
The clitellum becomes apparent in mature annelids, but may be hard to locate visually in younger annelids.
5.
:If you cut an earthworm in half, only one side has a clitellum, so doesn't that factor in?
6.
The clitellum is part of the reproductive system of clitellates, a subgroup of annelids which contains oligochaetes ( earthworms ) and hirudineans ( leeches ).
7.
An adult earthworm develops a belt-like glandular swelling, called the clitellum, which covers several segments toward the front part of the animal.
8.
The clitellum is a thick, saddle-like ring found in the epidermis ( skin ) of the worm, usually with a light-colored pigment.
9.
Maturity has been reported to occur around 16 days at 20�C, the clitellum ( see above ) forming when the worms are about 3 ~ 4 mm.
10.
:The first worm is clearly an ( oligochaete ) earthworm, given the obvious and diagnostic feature of the clitellum, and the lack of the specializations of a leech.
