The beef tapeworm Taenia saginata is similar to the pork tapeworm Taenia solium, in structure and life history. It is the commonest tapeworm of man with a much greater incidence than that of T. solium. Its intermediate hosts are cattle and buffaloes. It is longer than T.solium, usually attaining a length upto 12 meters or more. Scolex bears four strong, rounded, adhesive suckers but lacks hooks. Strobila comprises up to 2,000 proglottids. A gravid proglottid contains about 100,000 eggs. Uterus of gravid proglottids has 15 to 35 branches on either side.

Difference between Taenia saginata and Taenia solium:
Absence of scolex hooks:
- Taenia saginata lacks scolex hooks, which are present in Taenia solium. Scolex hooks are structures on the head of the tapeworm that help it attach to the host's intestinal wall.
Presence of scolex hooks in Taenia solium:
- Taenia solium has scolex hooks, which aid in its attachment to the host's intestine, allowing it to establish itself and absorb nutrients.
Implications of absence of scolex hooks in Taenia saginata:
- The absence of scolex hooks in Taenia saginata means that this tapeworm relies on other mechanisms for attachment and nutrient absorption in the host's intestine.
Significance of scolex hooks in Taenia solium:
- The presence of scolex hooks in Taenia solium is an adaptation that enhances its ability to anchor itself firmly in the host's intestine, facilitating its survival and reproduction.
Conclusion:
- In summary, the absence of scolex hooks in Taenia saginata distinguishes it from Taenia solium, which possesses these structures. This difference has implications for the tapeworms' mechanisms of attachment and survival within their respective hosts.
