scolex


scolex
The head or anterior end of a tapeworm attached by suckers, and frequently by rostellar hooks, to the wall of the intestine; it is formed within the hydatid cyst in Echinococcus, within a cysticercus in Taenia, a cysticercoid in Hymenolepis, or by a plerocercoid, as in Diphyllobothrium latum. The form of the s. varies greatly, the most familiar being rounded or club-shaped with four circular muscular suckers and an armed or unarmed rostellum, or a spatulate flattened s. with a pair of slitlike suckers (bothria) and no rostellum, as in Diphyllobothrium and its allies. Other forms have complex leaflike, cup-shaped, or fimbriated shapes, or retractile, multiply spined proboscides. These varied forms characterize the orders of cestodes, which are particularly well developed as parasites of sharks and skates or rays. [G. skolex, a worm]
