What is it?????????

This is my sketch and understanding of a cestoda. This Platyhelminthe parasites is the concept of my building. You may ask your self what is a Cestoda? Cestoda is a tapeworm.

Facts of a Tape worm
wikipedia :Cestoda is a class of parasitic flatworms, commonly called tapeworms, that live in the digestive tract of vertebrates as adults and often in the bodies of various animals as juveniles. Taenia saginata, the beef tapeworm, can grow up to 40 feet long (12 m); other species may grow to over 100 feet (30 m).

Reason
I know its weird and The disgusting topic but i am interested in how the tapeworm it self can be an inspiration for a human disease library.
One of the aspect of tapeworm i will be looking at will be the concept of a host. I am intrigue with the whole idea that a tapeworm needs a host to survive. Another aspect of the tape worm i will be looking at is the strobila. The strobila are the body segments of the tapeworm.
