The number of segments between prostomiun and clitellum?
There are about 30 segments between the prostomium and clitellum of an earthworm. actually this question asked as differently as "How many segments are between the prostomium and clitellum of an earthworm?" see answer for this question.
How many segments are there in front of the clittelum?
There are 14 segments in front of the clitellum in an earthworm.
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.

How many body segmants all insects have?
3
A pentegon has how many line segmants?
A pentagon has five line segments.
How many body segmants do flies have?
3, like most insects.
How many line segments need to draw hexagon?
How many Line Segmants are in a Hexagon?
How many line segmants are in a decagon?
A decagon has 10 sides and 35 diagonals
How many nephridiopores are in each segment of the earthworm?
Except for the first and last segments, which have no setae, there are eight tiny bristle-like structures that can not be seen with the naked eye called setae on each segment of an earthworm. The arrangement of the setae is one factor that helps in the identification of earthworms, as they can be closely or widely paired in four pairs or separate. Setae grip the soil to help the earthworm move about and sense the enviroment.
