The scolex bears an apical rounded rostellum surrounded by four suckers. The scolex bears four radially arranged suckers that surround the rostellum. "Oxymonas" is distinguishable by the rostellum, which can be thought of as a elongated proboscis. In comparison, lack of rostellum and hooks is the defining feature of "T. saginata". There is a rostellum separating the pollinia from the stigma. There are no rostellum and rostellar hooks, and the suckers are devoid of spines. The rostellum is composed of a system of microtubules. The rostellum remains invaginated in the apex of the organ. The rostellum is armed with two rows of chitinous spiny hooks. The rostellum is surrounded by suckers which are armed with spines. The rostellum is usually surrounded by two rows of rudimentary hooklets. Lack of hooks and a rostellum is an identifying feature from other "Taenia" species.
