ABSTRACT
Roundworm, or Nematode, a slender, cylindrical worm. Roundworms are of worldwide distribution and are found in freshwater and saltwater, in plants and animals, and in the soil. About 80,000 species are known, but zoologists estimate that nearly 1,000,000 species exist. Roundworms range in length from about 1/250 of an inch to 4 feet (0.1 mm to 1.2 m), depending on the species. They are usually colorless and are either short and spindle-shaped or long and threadlike.
