  1. ribbonlike flatworms that are parasitic in the intestines of humans and other vertebrates
  2. Any one of numerous species of cestode worms belonging to taenia and many allied genera. the body is long, flat, and composed of numerous segments or proglottids varying in shape, those toward the end of the body being much larger and longer than the anterior ones, and containing the fully developed sexual organs. the head is small, destitute of a mouth, but furnished with two or more suckers (which vary greatly in shape in different genera), and sometimes, also, with hooks for adhesion to the walls of the intestines of the animals in which they are parasitic. the larvae (see cysticercus) live in the flesh of various creatures, and when swallowed by another animal of the right species develop into the mature tapeworm in its intestine. see illustration in appendix.

  4. An intestinal parasitic worm, adults of which are found in the intestine of vertebrates; the term is commonly restricted to members of the class cestoidea. tapeworms consist of a scolex, variously equipped with spined or sucking structures by which the worm is attached to the intestinal wall of the host, and strobila having several to many proglottids that lack a digestive tract at any stage of development. the ovum, entering the intestine of an appropriate intermediate host, hatches and the hexacanth penetrates the gut wall and develops into a specific larval form (cysticercoid, cysticercus, hydatid, strobilocercus), which develops into an adult when the intermediate host is ingested by the proper final host. a three-host cycle with a swimming coracidium, procercoid and plerocercoid (sparganum) larva, and adult intestinal worm is found in aquatic life cycles, as in diphyllobothrium latu
