Cestoda
Cestoda (
Cestoidea) is a
class of
parasitic flatworms, of the phylum
Platyhelminthes. Biologists informally refer to them as cestodes. The best-known species are commonly called
tapeworms. All cestodes are parasitic and their life histories vary, but typically they live in the
digestive tracts of
vertebrates as adults, and often in the bodies of other species of
animals as juveniles. Over a thousand species have been described, and all vertebrate species may be parasitised by at least one species of tapeworm.

Tapeworm
(n.)
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.
