The species that reside in marine habitats are colorful while terrestrial and interstitial species lack brightness. It is used as a storage area for the gametes and it serves as a hydrostatic skeleton for the movement. Their reproductive, excretory, and muscular systems are relatively complete as well. Anti-parasite medicines or deworming medicines are available over-the-counter that are used for the treatment. The goal of each game is to eliminate all Worms in the enemy's team.

The most common parasite worms to cause infections in humans are roundworms, tapeworms, pinworms, hookworms, and threadworms. Worms may live in soil or water. Hookworms are transmitted to humans through contaminated soil or feces. Certain imaging tests like CT scan, MRI, and X-rays are also done to evaluate the extent of organ damage that may have occurred due to worm infestation. They are also capable of traveling outside the intestines to other tissues and muscles. A larval stage is absent. These tunnels are extremely important for plant life as they create a path for water and air, which is essential for the survival of plant life.

All members of this group, except leeches, have setae that are chitinous, hair-like projections from the cuticle. Earthworms can regenerate their bodies. Some are caught from food. The body of these annelids has a definite number of segments. The group Annelida includes earthworms, leeches, and polychaete worms. They do not grow too big. Worms usually lack appendages; polychaete annelids are a conspicuous exception. The skin serves as the medium for gaseous exchange. They can easily pierce through the skin. Plasmids are located at their posterior end, if present. Wikis. Some of the worms in this group are parasites.
