Taenia solium
Habitat
The pork tapeworm has several different habitats depending on the stage in its life cycle. * The preadult tapeworm and adult tapeworm can be found in the small intestine of a human host. * The proglottid segments full of eggs are found in the host feces, and in the external environment where the feces are released. Temperature is known to effect egg survival. If the habitat is colder than 10 degrees Celsius or above room temperature, the eggs can easily perish. * The oncosphere, this stage takes place inside the pig intermediate host. The habitat of the oncosphere is the gut and tissue of the pig host and continues its life stage in the muscle and brain of the pig in the cysticercus stage. * The cysticercus form is also capable of surviving in a human host, living in the muscles and the brain.

Physical Description
The morphology of the adult pork tapeworm is divided into three parts: * Scolex - is the head of the tapeworm, positioned at the anterior end of the organism. - acts as an attachment device with four suckers, hooks and rostellum - used to attach itself to the intestine of the host
* Neck- is an elongated region between the scolex and the stroblia. * Stroblia- contains the bulk of the systems of the tapeworm * has an average length of 2-3 m * It consists of multiple segments called proglottids
As a monoecious species, every single proglottid contains both the male and female reproductive systems. The proglottids mature sexually as they progress in the posterior direction of the strobila
The pork tapeworm does not have a digestive system, but is composed of the following systems: * Tegument
