It is the part of an earthworm that when the worm is mature will hold the fertilized egg and then make a cocoon to hold the zygote worm. It is used in reproduction and helps to distinguish the worm's anterior end.

∙ 16y agoIn earthworms and some other annelids, the clitellum is a thickened glandular section of the body wall that secretes a viscid sac in which the eggs are deposited. Once the eggs have been deposited in the sac, the clitellum slides off of the earthworm's body.

Also known as a clitellum/egg capsule. Holds the females eggs.
How many body segments does an earthworm have?
InvertebratesEarthworms are invertebrates. That is, they do not have a backbone. Insects, sea stars, spiders, jellyfish, and millipedes are other examples of invertebrate animals.SegmentsStudy the illustration of an earthworm shown below. You will notice that earthworms have long, cylindrical body that is divided into similar segments. The grooves that extend around the body of the worm show the arrangement of the segments.Some species of earthworms have a body composed of over 100 segments. How many segments does your earthworm have?SymmetryEarthworms have bilateral symmetry. This means that if you cut the earthworm down the centerline, the left side of the body would be identical to the right side.Body ColoursOne of the key features of an earthworm is the colour of its body. Some species of earthworms have a dark-red or red-violet body while other species are muddy-green. However, there are species that do not have these colours. For the purposes ofWorm Watch, these animals are said to have "other body colours."ProstomiumSome species of earthworms have a tongue-like lobe above the mouth called prostomium. The prostomium is actually a sensory device. Earthworms do not have a nose, eyes, ears, or hands to gather sensory information about their environment. Instead, they depend on their prostomium and sensory receptors in their skin to "feel" their way through the soil.PeristomiumThe first body segment is called theperistomium. The peristomium contains the mouth.ClitellumAdult (sexually mature) earthworms have a distinct swelling called a clitellum. It is located about one-third of the way down the earthworm. The clitellum is often white or orange in colour. It produces most of the material secreted to form earthworm cocoons. The clitellum forms a band that can be flared, non-flared, saddle-shaped, or annular. It is generally found between segments 26 and 33.The clitellum is only found on adult worms. Young or juvenile worms do not have a clitellum. The clitellum of each species of earthworm has a distinct colour, size, and shape. Another key structure found on the clitellum is thetubercula pubertatis.The diagram shows the shape and structure of the clitellum. They may have any combination of shapes.Tubercula Pubertatis (TP)The tubercula pubertatis (TP) is another structure used to identify earthworms. The TP are glandular swellings located on both sides of the clitellum. They can assume a variety of shapes such as long and narrow, triangular, or sucker-like.The shape and location of the tubercula pubertatis (TP) on the clitellum are key features used to identify mature earthworms.]Genital Tumescences (GT)The genital tumescences (GT) are areas of modified epidermis (skin) that do not have distinct boundaries. These are openings through which follicles of genital setae open.The pattern and location of the GT are important clues to identifying different species of earthworms.]AnteriorLocate the clitellum of a mature earthworm. The shorter region to one side of the clitellum is the anterior or head-end of the animal. This end of the worm is usually more pointed than the posterior end of the animal.The prostomium is the first segment at the anterior end of the animal.PosteriorLocate the clitellum of a mature earthworm. The longer region is the posterior or tail end of the earthworm.DorsalThe top-side of an animal is called the dorsal surface. For example, the fin you see in all shark movies shows the dorsal fin of a shark just before it attacks. The dorsal surface of some species of earthworms is darker than its ventral surface.VentralThe bottom-side of an animal is called the ventralsurface. In many animals, the ventral surface is a lighter colour or shade than the dorsal surface.PeriproctThe periproct is the last segment of an earthworm.SetaeEach segment, except the first and last, have tiny bristle-like structures called setae. These structures help the earthworm to move and act to sense the environment.The number and arrangement of setae are important clues to the identification of earthworms.]EpidermisThe epidermis is the name for the skin of an earthworm. It is the outer layer of worm and it secretes a mucous.
Can earthworms loose their clitellum?
Maybe but they can't make cocoons
Which phylum is a worm with a coelom and clitellum?
Oligochates, aka earthworms
The clitellum functions as part of the system in earthworms.?
The clitellum is a part of the earthworm's reproductive system. It is the part of the worm that makes the egg cocoon.
How do worms reprpoduce?
earthworms, the ones that come out after it rains outside, reproduce using the clitellum and exchanging sperm. the clitellum secretes a cocoon that envelops the two worms and they produce eggs and exchange sperm.
What is the difference between an earthworm and a shark?
Blackworms live in the water and earthworms live in the soil of the earth. Blackworms are brown in color and earthworms are pink in color. Blackworms have setea and clitellum and earthworms have chatea. Blackworm is smaller than the earth worm.CORRECTION: blackwormsactually have chatea and earthworms have setea and clitellum
What function does the clitellum serve during reproduction?
The function of a worm or leeches clitellum is to secrete a viscid sac where their eggs are laid. It is located at the end of their body.
What organ system does the clitellum?
Clitellum
The ring on an Earth worm that produces mucus during reproduction?
Earthworms does produce mucus. This is during reproduction.
How many segments are in the clittelum?
Usually 3 segments are covered by clitellum in earth worms. This region is between 14 to 16 in case of pheretima posthuma and this differs in other earthworms.
What is the function of an earthworms ovary?
It produced eggs .
What is function of lateral hearts in earthworms?
keeps it alive
How to find earthworms head?
you look for the weird ring around a part of their body,(the clitellum), and the side that its closest to is the head.Hope it helps, and if it doesnt go to : http://www.backyardnature.net/earthwrm.htm. it helped me! the opposite side where is poops
