The scolex or "head" of a tapeworm. Attaches to the intestine of the definitive host. In some groups, the scolex is dominated by bothria, which are sometimes called "sucking grooves," and which function like suction cups. Other groups have hooks and suckers that aid in attachment. Cyclophyllid cestodes can be identified by the presence of four suckers on their scolex, though they may have other structures as well.
while the scolex is often the most distinctive part of an adult tapeworm, it is often unavailable in a clinical setting, as it is inside the patient. Thus, identifying eggs and proglottids in feces is important.
