The body of<unk>  is yellowish-white in colour, about 350 cm long and 1 cm broad, divided into the anterior scolex, followed by a short neck and a highly extended body proper called strobila. It is an acoelomate animal with no body cavity or digestive system. The scolex bears four simple suckers as attachment organs to the intestinal wall of the host. The distinct rostellum on the scolex, the large number of uterine twigs and the existence of posterior protuberance in adult are the defining characters. The rostellum is usually surrounded by two rows of rudimentary hooklets. In comparison, lack of rostellum and hooks is the defining feature of T. saginata. Moreover, the metacestode is different in having wart-like formations on the external surface of the bladder wall, which are absent in T. saginata. The strobila is composed of a chain of ribbon-like segments called proglottids. There are more than 700 proglottids in the strobila, but less than 1000 (~900), while T. saginata in comparison have more than 1000 proglottids. The proglottids are distinguishable into mature and gravid proglottids. Each mature proglottid contains a complete set of both male and female reproductive systems; hence it is hermaphrodite. Similar to T. saginata the uterus has 13 lateral branches in<unk> . The gravid proglottids are full of fertilised eggs. The number of eggs in gravid proglottids differs from 44,180 to 132,500, with an average number of 90,051. It is unique in having posterior protuberances in the gravid proglottid, which are absent in other taenids including T. saginata. The cysticerci of<unk>  are typically smaller than those of other human taenids. They possess two rows of rudimentary hooks, unlike T. saginata, which has none. In addition the protoscolex of cysticercus (metacestode) has a sunken rostellum, while that of T. saginata has only an apical pit.
