| The scolex has long been known, and was regarded as a distinct parasite, with the name of cysticercus cellulos. |
| The compound scolex thus forms a sac or a group of sacs, the basis of hydatid tumors. |
| At the tapeworm's anterior end is a specialized segment called a scolex, which is usually covered with hooks or suckers and serves to anchor it to the host. |
| This vesicle, of a milky-white colour, and filled with liquid, is the scolex. |
| In this form the scolex is contained in a sac of connective tissue induced by the presence of the parasite. |
| The head, or scolex, bears suckers and often hooks, which are used for attachment to the host. |
