The rostellum is armed with two rows of spiny hooks, which are chitinous parasito tenia nature. After a short neck is the elongated body, the strobila. The entire body is covered by a covering called tegumentwhich is an absorptive layer consisting of a mat of minute hair-like microtriches.

The strobila is divided into segments called proglottids, to in number. Body growth starts from the neck region, so the oldest proglottids are at the posterior end. Thus, the three distinct proglottids are immature proglottids towards the neck, mature proglottids in the middle, and gravid proglottids at the posterior end.

In the secondary host, the eggs develop into oncospheres which bore through the intestinal wall and migrate to other parts of the body where the cysticerci form. The cycticerci can survive for several years in the animal.

Each microscopic cysticercus parasito tenia oval in shape, containing an inverted scolex specifically "protoscolex"which everts once the organism is inside the small intestine. This process of evagination is stimulated by bile juice and digestive enzymes of the host.

Using the scolex, it parasito tenia to the intestinal wall. It grows in size using nutrients from the surroundings.
