What are worms?
 
A worm is an long, thin animal that lives in the soil. They have a soft, long, rounded body and no legs or backbone.
 
There are thousands of different kinds of worms. The largest species measure many feet or meters long, while the smallest worm cannot be seen without a microscope. Worms usually live in soil; some live in water. Many worms eat small plants and animals, others feed on decaying matter. Still other types of worms live as parasites in various animals and plants causing a number of diseases. Most types of worms have a well-developed sense of touch. They also have specialized organs that respond to chemicals in their surroundings. Many species have a sense of sight, with eyes or eyespots on the head.
 
People mistakenly believe that caterpillars and grubs are worms. These animals are insects in their larval (juvenile) stage and do not resemble worms after they mature.
 
There are four main groups of worms: (1) flatworms, or Platy helminthes; (2) ribbon worms, or Nemertea; (3) roundworms, or Nematode; and (4) segmented worms, or Annelida. The study of worms is helminthology.
