A still more complicated form ofcystic worm is that known as Echinococcus, parasitic in the liver, lungs, etc.
The cystic worm while still encapsuled develops a head with suckers and hooks, becoming a Cysticercus.
The whole papilla eventually becomes everted, and then the cystic worm takes the form (fig.
This involution forms a papilliform projection on the inner surface of the wall of the cystic worm, with an axial cavity opening by a pore on the outer surface.
This is formed in an involution of the outer wall of the anterior extremity of the cystic worm.
Though the majority of cystic worms only develop one head, this is not invariably the case.
Cystic worms infest not only Mammalian forms, but lower Vertebrates, various fishes which form the food of other fishes, and Invertebrates liable to be preyed on by vertebrate hosts.
These cases may, it appears to me, be probably regarded as more primitive than the ordinary ones, where the cystic condition has become exaggerated as an effect of a parasitic life.
