[[File:Tapeworm_life_cycle.jpg]]|freash water fish tapeworm<br /> (''Diphyllobothrium latum'')<br /> Subtaxa: Eucestoda Tapeworms are [[parasitic flatworms]] meaning they spend their adult life inside of a host.[http://www.righthealth.com/Health/Tape%20Worms-s?lid=goog-ads-sb-8536643334] As an egg it stays on the ground or in the feces of the parent's host untill consumed by the intermediate host. The egg passes through most of the digestive system, thus at that short stage of life their enviornment is the digestive tract of the intermediate host. Once they reach the small intestine they hatch and the larvae burrows through the intestine wall. The second enviornmentin which they stay is in an organ(the brain, muscles, eyes and nearly any other organ) in their intermediate host. The tapeworm's final enviornment is its final host where it stays in the small intestine.(Porch, p458) | [[File:Tapeworm_life_cycle.jpg|left|250px]]|freash water fish tapeworm<br /> (''Diphyllobothrium latum'')<br /> Subtaxa: Eucestoda Tapeworms are [[parasitic flatworms]] meaning they spend their adult life inside of a host.[http://www.righthealth.com/Health/Tape%20Worms-s?lid=goog-ads-sb-8536643334] As an egg it stays on the ground or in the feces of the parent's host untill consumed by the intermediate host.

The tapeworm stays in the small intestine of its host for its entire adult life protected by a thick tegument. It must live there due to the fact that it has no digestive tract of its own thus it must absorbe the nutrents where most of the digestive work has been done.[http://www.merck.com/mmpe/sec14/ch184/ch184a.html] | The tapeworm stays in the small intestine of its host for its entire adult life protected by a thick tegument.
