Roundworms live all over the world.
Roundworms live in water and soil everywhere except the desert. A few species are parasites of plants and animals. Parasites (PAIR-uh-sites) are animals or plants that live on or in other animals or plants, or hosts, without helping them and usually harming them.
Most roundworms eat bacteria, fungi, and tiny growths in the soil. The parasite species feed on blood, body fluids, intestinal contents, and mucus in their hosts.
Roundworms move their spear in and out of their prey, puncturing the cells and emptying the contents. Most species of roundworms have two sexes, but in a few species the worms make both eggs and sperm. Fertilization (FUR-teh-lih-ZAY-shun), or the uniting of egg and sperm to start development, takes place inside the females, who then lay the eggs.
Roundworms are not considered threatened or endangered.
