I am in 7th grade and we are learning about segmented worms. i got this information from my textbook. Worms have a tube like body with a bristle like structure called setae. Setae help keep worms in the soil and help them move. Segmented worms also have bilateral symmetry, a body cavity that holds the organs, and two openings -- mouth and an anus.
The arthropods (for instance, centipedes) are believed to have descended from the annelids (segmented worms).
Earthworms have many segments, typically ranging from 100 to 150 segments. These segments allow for flexibility and movement in the worm's body. Each segment contains muscles and nerve cells that help the earthworm perform its daily activities.

This is a humor question. Because of their name, Christmas tree worms (Spirobranchus giganteus) do not need the holiday to 'celebrate'. They are a type of polychaete, a group of segmented worms.
It depends what type of warm you are referring to. Flatworms belong Platyhelminthes Tubeworms belong to Nematodes and Segmented worms belong to Annelids Centipedes and Millipedes are not worms. They belong to the Arthropod Phylum.
Annelids are a type of segmented worms found in marine, freshwater, and terrestrial habitats. They have a cylindrical body with ring-like segments and exhibit bilateral symmetry. Examples of annelids include earthworms, leeches, and marine bristle worms.
Type of worms are:* Acoelomorpha * Platyhelminthes (flatworms) * Cestoda (tapeworms)** Trematoda (flukes)** Monogenea ** Turbellaria (planarians)* Acanthocephales * Kinorhyncha (mud dragons)* Annelida (segmented worms) * Polychaeta** Oligochaeta ** Hirudinida (leeches)* Nemertea (ribbon worms) * Echiura (spoon worms) * Sipuncula (peanut worms) * Nematoda(roundworms)* Nematomorpha (horsehair worms or gordian worms) * Priapulida (penis worms) * Gnathostomulida (jaw worms)
Earthworms, which are a type of segmented worm, help out plans by digging tunnels in the soil which gives plants oxygen.
Yes. However, this is not a true coelom. Roundworms are pseudocoelomates -- their mesoderm lines the endoderm and ectoderm, but there is no connection between the two. Therefore, it does not satisfy the definition of a coelom. However, since there is a body cavity still, this animal is said to be a pseudocoelomate.
segmented worms have a closed circulatory system.in a closed circulatory system, blood moves only within a connected network of tubes called blood vessels.
Only parasitic worms adapted to living in digestive tracts can do so. Worms of that type live and grow in the intestines rather than the stomach.
