CESTODA

Cestoda (the Cestodes) is a class of Phylum platyhelminthes commonly known as the tapeworms. They are internal parasites lacking an alimentary canal. They have no definite sense organs, and the nervous system is poorly developed. The cuticle is thick and many-layered. Hooks and/or suckers are limited to one end. They have great reproductive powers, both sexual and asexual.
