[[File:Proglottid_chain.jpg‎|left|250px]]|human tapeworm<br />  a chain of proglottidsA tapeworm's life cycle starts as an egg(once contained in a proglottid) that has been excreted in a host's feces. Once eaten by the intermediate host the egg travels to the intestine where it hatches. The newly hatched larvae(in most species it has a fully developed scolex) than burrows into and through the intestine wall into an organ or the body cavity.  [http://animals.jrank.org/pages/1527/Tapeworms-Cestoda-BEHAVIOR-REPRODUCTION.html] The larvae stays in an organ(for example; the muscles, eyes, brain or almost any other organ of the body) of the intermideate .(Porch, p458) Once it is eaten by the intermedeate host it goes through the digestive system to the small intestine wherhost(which can be almost any vertebrate) untill it is consumed by the [[final host]], though some species have multiple [[intermedeate hosts]] the scolices of larvae attatch. After attatchment to the inside of the intestine the tapeworm starts producing proglottids and the [[strobila]](the bulk of the tapeworm's body) forms. After more developement the proglotteds start producing eggs.[http://animals.jrank.org/pages/1527/Tapeworms-Cestoda-BEHAVIOR-REPRODUCTION.html] When fully matured a proglottid breaks off(a terminal proglotted) it is excreted in the host's feces.[http://www.factmonster.com/ce6/sci/A0861442.html]
